In vitro and in vivo assembly protocols for CPMV capsid subunits are not yet established well. The cowpea weevil, Callosobruchus maculatus F. (Coleoptera: Bruchidae), can cause up to 100% yield loss of harvested cowpea seeds in a few months in storages in West Africa (Lienard and Seck 1994). The determinate, bush types may yield better on closer row spacing. CPMV has been successfully used for display of several heterologous peptides to induce immune response. Leaves: The first pair of leaves of a Cowpea plant is opposite arranged, while the remaining leaves have an alternate patterns and are trifoliate. In the U.S., the largest market class of cowpea harvested as dried seed is black-eyed pea and pink-eyed/purple hull southern pea. Price for dried black-eyed or pink-eyed/purple hull peas fluctuates due to normal production and demand factors, but ranges from $0.20-0.25/lb. Similar transformation techniques combined with transgenically induced PTGS (posttranscriptional gene silencing) or RNAi can be exploited for the control of both DNA and RNA viruses infecting cowpea. Mohar Singh, ... Ishwari Singh Bisht, in Genetic and Genomic Resources of Grain Legume Improvement, 2013. I.R.A.P. Variation in the performance of contrasting maturity class of cowpea cultivars (Vigna unguiculata L. Walp) in the derived Savanna By O.S. Manchester and coworkers discovered that fluorescently labeled CPMV has an endogenous capacity to be taken up by vascular endothelial cells and can be used as an intravital imaging probe to visualize the vasculature and blood flow to a depth of up to 500 μm for 72 h in living mouse and chick embryos (Lewis et al., 2006). TAXONOMY Kingdom : Plantae Class : Dicotyledon Sub-class : Polypetalous Order : Rosales Family : Fabaceae Sub Family :Papiloinaceae Genus : Vigna Species : Unguiculata 6. Possilbe insects are Mexican bean beetle, bean leaf beetles, cowpea curculio, aphids, green stink bug, lesser cornstalk borer and weevils (when in storage). The efficacy of eCPMV as an in situ vaccine was demonstrated in mouse models of metastatic melanoma, breast cancer, ovarian cancer, and colon cancer, where it induced antitumor immune response by triggering activation and infiltration of neutrophils, resulting in a chemo/cytokine profile that leads to activation of adaptive immunity. Besides cultivated cowpea lines, some accessions of wild cowpea relatives are also conserved in the gene bank at IITA. sesquipedalis (common names: yardlong bean and asparagus bean), especially in Asia. Over 80% of cowpea production is confined to West Africa with Niger, Nigeria and Burkina Faso alone contributing 83% of the production area and 77% of the total production (FAOSTAT, 2012). is a leguminous species used as food, forage, and vegetable crop mainly in the tropics (Steele, 1972). The plant's Family is Fabaceae. is cultivated widely in the tropics and has multipurpose uses: as food for human beings, fodder for livestock and atmospheric nitrogen fixers. A variety of birds, including wild turkey, eat the seeds and the plant can be used by quail as cover. Many cowpea varieties with high yield potential have been developed and adopted by the farmers. High temperatures can cause flower and pod drop, resulting in low grain yield. Potassium and phosphorus needs have not been studied for cowpea in Missouri. Studies in the genus Cladosporium sensu lato. Cowpea is well-adapted to sandy soils, and will perform well on rich, well drained soils, but should not be grown on wet or poorly drained soils. The optimum temperature for growth and development is around 30 °C. Forage cultivars - adapted for use as fodder, or cover crop use. Cowpea (Vigna unguiculata (L) Walp. Mostly, root growth occurs within the top soil layer, but in times of drought, cowpea can grow a tap root as long as 8 ft to reach moisture in the deep soil profile. It is an important crop in Africa, its probable center of origin, but is also grown in Brazil, India, Southeast Asia, and the United States. Proper site selection is important. However, row crop cultivation may be necessary with cowpeas, depending on the weed pressure, soil conditions, and rainfall. Infected plant cells show a number of characteristic cytological changes. Intratumoral delivery of magnetic nanoparticle (mNP) to induce hyperthermia and eCPMV in combination improved local and systemic tumor treatment efficacy (retardation of secondary tumor growth (abscopal effect) and resisting tumor rechallenge) in the C3H mouse/MTG-B mammary adenocarcinoma and C57-B6 mouse/B-16-F10 melanoma cancer cell models (Hoopes et al., 2017a). Cowpea family is the family in which it has some properties in common with other plants in that family. Climate • Cowpea can grow in tropical and sub-tropical climate. Cowpea plays an important role in the traditional diets in many regions of the world, especially Asia, Africa, and South America, which include most of the world's developing countries. We use cookies to help provide and enhance our service and tailor content and ads. It is a 30 nm icosahedral virus and consists of bipartite positive-sense, single-stranded RNA genome with each RNA molecule encapsidated in a separate particle. Introduction. 52 000 and 58 000, the former predominating, the other containing subunits of mol. However, resistance to multiple virus infection is scarce in cowpea, and recent studies are putting greater emphasis on multiple virus resistance. Multivalent display of antiviral molecules and carbohydrates on CPMV facilitated their usage for therapeutic applications (Lomonossoff and Evans, 2011; Koudelka et al., 2015; Hefferon, 2017). In Kenya, cowpea yield is 0.53 tonnes/ha of dry seeds which is low compared to 1.86 tonnes/ha in USA. They are often cooked with water and canned or frozen. According to Valenzuela and Smith (2002), cowpea is a summer annual legume with trifoliate leaves. Allen, in Encyclopedia of Human Nutrition (Third Edition), 2013. It is a valuable crop as it is a highly palatable food source and the whole plant can be used as forage for animals. Cowpea cultivars grown for the immature green pods that are used as a vegetable are variously known as asparagus bean, snake bean, and yard-long bean; when grown for dry or immature seed, they are known as black-eye pea, kaffir pea, china pea, and southern bean. 1). (2003). The Plants Database includes the following 27 species of Vigna .Click below on a thumbnail map or name for species profiles. As a legume, cowpea fixes its own nitrogen, and does not need nitrogen fertilizer. The plant produces clusters of flowers at the end of a peduncle (flower stalk) and 2–3 seed pods per peduncle. OF NEEM AND GALLIC AS PESTICIDE IN COWPEA STORAGE Isinkaye, O D', Oke D. O² . Copyright © 2021 Elsevier B.V. or its licensors or contributors. Wen and Steinmetz (2014) developed a bottom-up approach for the synthesis of CPMV nanoparticles, dimers and assemblies containing targeting ligands (cyclic RGD peptides), and fluorescent dyes and found that symmetrical presentation of RGD peptides and the dimerization of nanoparticles increased the efficacy of cancer cell targeting. This article has been rated as GA-Class on the project's quality scale. Cowpea, Vigna unguiculata (L.) Walp.—whether utilized for green pods (vegetable) or dry seed (pulse)—forms an important component of farming systems from the arid to the humid tropics. Ethnobotany: Cowpea has been a … If several Missouri farmers worked together on a common delivery point for dried black-eyed or pink-eyed/purple hull peas, transportation costs could be reduced. This hybrid PDT-CPMV carrier system was effective in killing both melanoma cells and macrophages in vitro (Wen et al., 2016). Preclinical studies in a carotid artery photochemical injury model of thrombosis confirmed thrombus homing of the nanoprobes, with the elongated TMV rods exhibiting significantly greater attachment to thrombi than icosahedral CPMV (Wen et al., 2015b,c). The seed pod is typically 3 to 6 inches long and has 6 to 13 seeds per pod. Many cowpea cultivars have a vining growth habit, but modern plant breeding has also led to more upright, bush-type cultivars. Field trials were done in Missouri on 30 inch row spacings, and the vine type varieties filled in the row well. Proximate analysis of cowpea CHAPTER ONE/INTRODUCTON Background to the Study Cowpeas (Vigna unguiculata and Vigna Senensis) are important grain legumes in East and West Africa as well other developing countries (Dovlo et al. Gene. Vigna unguiculata (Cowpea) Status. A number of varieties have been tested in mid-Missouri, with the better varieties ranging in yield from 1,400 to 1,800 pounds per acre full season, and 800 to 1,500 pounds per acre double cropped. Native nucleic acid content of CPMV virions was used as an electrostatic sponge to attract imaging agents and therapeutic molecules via simple infusion technique (Yildiz et al., 2013). Most mice rechallenged with tumors on the opposite flank completely rejected the rechallenged tumor (Lizotte et al., 2016). SOM, P. HAZRA, in Genetic Improvement of Vegetable Crops, 1993. Concerning Cladosporium vignae, causal organism of leaf and pod spot of cowpea (Vigna unguiculata) and leaf blight of Lespedeza bicolor. In southeastern production areas, the major insect pest is cowpea curculio, and the major disease is root-knot, a severe root disease induced by root-knot nematodes (Meloidogyne spp.). The extreme variability of the species has led to a number of commercial cultivars grouped by the variance in bean shape, size and color. However, some cowpeas are harvested while the seed are high moisture, and sold fresh, typically referred to as southern peas. Murthy, in Recent Developments in Applied Microbiology and Biochemistry, 2019. The seeds are "crowded" in the pod and also tend to be globular in shape. Cowpea fixes atmosphere nitrogen through symbiosis with nodule bacteria (Shiringani and Shimeles, 2011). Cowpea is susceptible to over 140 viruses and about 20 of these viruses are known to have widespread distribution (reviewed in Hampton & Thottappilly, 2003). wt. Efforts are continuing to develop better performing varieties using conventional breeding procedures, while molecular tools are being developed to facilitate progress in cowpea breeding. The viruses infecting cowpea are vectored by aphids (BCMV-BlCM, CABMV, and CMV), by beetles (CCMV, CPMV, CPSMV, CPMoV, and SBMV), or by whiteflies (CPMMV and CGMV). Unreviewed-Annotation score: -Experimental evidence at transcript level i. Weed Control Options are less extensive than for soybeans, but several products are available. Resistance to two potyviruses was found in germplasm accessions, TVu401, TVu1453, and TVu1948, and in breeding lines, IT82D-885, IT28D-889, and IT82E-60 (Gumedzoe, Rossel, Thottappilly, Asselin, & Huguenot, 1998). Reports on anthocyanin content of cowpea peel and boiled cowpea extract are given by Kazuko et al. Production costs for cowpea are very similar to soybeans, with primary differences being post-harvest cleaning and transportation. Dried black-eyed peas and pink-eyed/purple hull peas are used for food products. However, insect control measures by using pesticides and cultural measures other than growing virus-free seed is seldom feasible for smallholder farmers in SSA. Walp.) It does well and most popular in the semi-arid of the tropics where other food legumes do not perform well (Sankie et al., 2012). 51 Figure 3 Dual-purpose cowpea … In Nigeria, infection of cowpeas with CPMV causes a great reduction in leaf area, flower production and yield. Introduction to Growing Cowpeas. • Germination of cowpea is better between 12-15°C, whereas proper growth and development takes place between 27-350 C . Therefore, measures targeting vector control, cultural management to eliminate volunteer sources including use of virus-free seed stocks (Biemond et al., 2013; Sharma & Varma, 1984) and resistant cultivars (reviewed in Hampton & Thottappilly, 2003) can significantly reduce the incidence, spread, and damage to cowpea crops. Black-eyed or pink-eyed/purple hull peas - the seeds are white with a black eye round the hilum. Some buyers will want the seed cleaned and bagged, while others will take the grain in bulk form and clean it themselves. The hydrodynamic behavior of cowpea chlorotic mottle virus (CCMV) suggests that it exists as two forms, depending on pH. Another common product is the canned or frozen product, which is cooked with water prior to canning or freezing. Subsequently it has been found to occur in Nigeria, Kenya, Tanzania, Japan, Surinam and Cuba. In Kenya, cowpea yield is 0.53 tonnes/ha of dry seeds which is low compared to 1.86 tonnes/ha in USA. This sample Beans/Cowpea Farming Business Plan In Nigeria can be used for Grant Applications, Bank Loans, Proposal writing, Business Concept Note, Competitions etc. Sakariyawo, P.A.S. The crop is prone to frost. Progress in the development of varieties with superior performance depends on the availability of germplasm with desired traits. These versatile and hardy peas from the Vigna genus are able to grow in harsh, unforgiving climates, providing people in those areas with a dense form of nutrients. *Pesticides mentioned as being labeled in this publication are based on reference lists published in the Thomson Publications "Quick Guide" on crop pesticides, 2002 edition. Cowpea, Vigna unguiculata, is a climbing annual in the family Fabaceae grown for its edible seeds and pods. Cowpeas are grown on some farms in the southeast Missouri, where they are double cropped after wheat. However, they are all the species Vigna unguiculata (L.) Walp., which in older references may be identified as Vigna sinensis (L.). This sample Beans/Cowpea Farming Business Plan In Nigeria can be used for Grant Applications, Bank Loans, Proposal writing, Business Concept Note, Competitions etc. And cowpea tolerates droughts, which are increasing across sub-Saharan Africa. Spoon the curry into serving bowls and set out fresh rotis or chapatis. P-ISSN: Response of vegetable cowpea [2349-8234 www.phytojournal.com JPP 2020; 9(6): 1070-1074 Received: 17-08-2020 Accepted: 05-10-2020 Sandeep Kaur M. Sc. Cowpea is the most widely cultivated indigenous legume in SSA, especially by smallholder farmers, because of its tolerance to drought and ability to thrive in poor soils. The immunosuppressive tumor microenvironment enables cancer to resist immunotherapies. Okeleye and S.G. Aderibigbe The recombinant protein was secreted into the culture medium and purified by affinity chromatography on a chitin matrix. High levels of resistance to several cowpea viruses, especially multiple virus infections are limited in cowpea germplasm. The particles were negatively stained with 2% (w/v) uranyl acetate. Plants that are cultivated for fodder and green manure are sown in rows spaced 30–35 cm apart or are planted broadcast. Nigeria. Add the cowpea beans and stir. These efforts have already resulted in identification of multiple virus resistance to three virus species (BCMV-BlCM, CMV, and SBMV) in breeding lines, IT98K-1092-1 and IT97K-1042-3 (Ogunsola, Fatokun, Boukar, Ilori, & Kumar, 2010). It is a broadly adapted and highly variable crop cultivated all around the world primarily as a food legume especially in tropical and subtropical areas. Textural class Sandy soil also be an indicator of the response of cowpea lines to low P soils. Southern peas are shelled green CPMV capsid is composed of 60 copies each of two different CP subunits (termed as small, 24 kDa, and large, 42 kDa) with pseudo T = 3 icosahedral symmetry. It causes typical mosaic symptoms on infected plants (Fig. The following fungicides* are registered for cowpeas—Maxim, Maxim-XL, Mefenoxam, Metalaxyl, Mycostop, Ridomil-Gold and Thiram. This article has been rated as GA-Class. CABMV resistance was conditioned by a single recessive gene or more than one recessive gene (Orawu, Melis, Laing, & Derera, 2013). Some varieties of cowpea are used specifically for wildlife purposes (Ball et al., 2007). The exterior surface of the CPMV capsid has been extensively modified using naturally occurring or genetically engineered exposed lysine, cysteine, tyrosines, and aspartic and glutamic acid residues by using standard chemical conjugation methods and conjugating cross-linkers to attach several reagents such as Au nanoparticles, redox reactive methyl viologen moieties, organometallic ferrocene carboxylate moieties, fluorophores, biotin, PEG chains, stilbene derivatives, carbohydrates, heterologous proteins (e.g., human holo-transferrin, T4 lysozyme, the LRR domian of internalin B and the Intron 8 gene product of the HER2 tyrosine kinase receptor), antibodies, oligonucleotides, semiconductor quantum dots and fullerenes. Various soups and bean mixes will incorporate this product as well. They compare well with soybeans on sandy or drought prone soils. Similar genomic resources are required to fast track development of virus-resistant cowpea. Vigna unguiculata (Cowpea) Status. The yardlong bean is an intensely cultured, trellised vegetable crop that is grown widely in southeast Asia. The immature seeds, when cooked, are a medium to dark brown, very tender and have a delicate flavor. It is a subsistence crop, often intercropped with sorghum, maize and pearl millet. The Plants Database includes the following 5 subspecies of Vigna unguiculata . • It is a warm season crop and drought-hardy but can not tolerate cold weather. PROTEINS: Structure, Function, and Bioinformatics 63:662– 670 (2006) Molecular Modeling and Inhibitory Activity of Cowpea Cystatin against Bean Bruchid Pests Juliana M. Aguiar,1 Octa´vio L. Franco,2,3 Daniel J.Rigden,2,4 Carlos Bloch, Jr.,2 Ana C.S. Cowpea is one of the most ancient crops known to man. (IPM CRSP, 2000). Cowpea grown as a dried pea product can be direct combined using a platform head or a row crop head. Cowpea is a heat-loving and drought-tolerant crop. M. Hema, ... M.R.N. Since the pods are relatively long, some will touch the ground or be close to it, making it important to run the grain table close to the gound. A double cropping practice with no additional fertilizer would keep the production costs fairly minimal for cowpea. Some are short, upright bush types, and others are tall and vinelike. 1. The search for resistant cowpea (Vigna unguiculata (L.)) Walp. George P. Lomonossoff, in Reference Module in Life Sciences, 2020. wt. Cowpea is considered more tolerant to drought than soybeans and better adapted to sandy soils. Recent study by Ha et al. 170 000 which was heterogeneous; two components could be separated by gel electrophoresis at pH 4.0, one containing subunits of mol. Flores,6 Taˆnia Jacinto,6 Jose´ Xavier-Filho,1 Antonia E.A. White acre type - seeds are kidney shaped with a blunt end, semi-crowded and generally tan in color. There are three major subspecies of V. unguiculata; in addition to ssp. Root: Cowpea plants have a taproot and many spreading lateral roots in surface soil. • Cowpea can grow both in spring and rainy season in the plains. Although cowpeas benefit from good soils, their best niche, when compared to soybeans, is probably on sandy loam soils or in other moisture-limited situations. Cowpea has a number of common names, including … The grain provides valuable protein and the leaves are used as a nutritious vegetable. The elites of England actually considered it food just for the cows and preferred the English pea instead. Native CPMV and CPMV particles derivatized with lanthanide metal complexes were found to be safe and nontoxic, based on the biodistribution, toxicity, and pathology studies of these particles in vivo (Rae et al., 2005; Singh et al., 2007). this is open class study site. There are 4 cultivars able to be simulated: Banjo, Red Caloon, CPI28215, spreading. Clay types - these older varieties are medium to dark brown in color and kidney shaped, but are rarely grown. Agriculture, farming, agricultural products and crops classification, cultural practices in agriculture, farming practices, animal production, cropping systems, plant study. Beans/Cowpea Farming Business Plan in Nigeria. This low productivity is due to a host of diseases, insects, pests, parasitic weeds, drought, poor soils and low plant population density in the farmer’s field. Beans/Cowpea Farming Business Plan is a lucrative business that needs a lot of strategic Planning to start and a business coach like Dayo Adetiloye to help you start the … LOC114181557 class I heat shock protein-like [ (cowpea)] Gene ID: 114181557, updated on 15-Aug-2019. Crowder peas - seeds are black, speckled, and brown or brown-eyed. The new cowpea varieties are subject to approval by Ghana’s Ministry of Food and Agriculture based on recommendation by the National Varietal Release and Registration Committee, adds Asare, who is head of the Department of Molecular Biology and Biotechnology at Ghana’s University of Cape Coast. Function i Sites. this site functions with internal linking marked in colours. Major cowpea viruses include Cowpea Mild Mottle Virus (CPMMV), Cowpea aphid- borne mosaic virus (CABMV) and Cucumber Mosaic Virus (CMV). (B) Transmission electron micrographs of purified particles of CPMV at two different magnifications. More facts about Cowpea. With the exception of CGMV and CCMV, all the other viruses are known to be seed-transmitted at a variable rate between none to 55% depending on virus strain, cowpea genotype, and time of infection (Bashir & Hampton, 1996; Salem, Ehlers, Roberts, & Ng, 2010). LOW QUALITY PROTEIN: phenylalanine ammonia-lyase class 1 … Resistance in cowpea to BCMV-BlCM was attributed to a single recessive gene pair (Arshad, Bashir, Sharif, & Malik, 1998). Leaves will dry down but may not drop off completely. In nature, transmission is usually by leaf-feeding beetles, especially by members of the Chrysomelidae. These have not been a problem in Missouri field trials. ssp. As in most legumes, the amino acid profile complements cereal grains. A novel cowpea cultivar, designated 951135, is disclosed. The spreading type is typical of that found growing under smallholder conditions in southern Africa. Using the transgenic approach and mutational analysis of the 24 k Pro gene, Fan, Niroula, Fildstein, and Bruening (2011) demonstrated the participation of protease in eliciting extreme resistance. Application of DNA marker technologies for cowpea improvement has been very slow when compared to many other crops. Cowpea is primarily used in the form of dry seeds, fodder, green pod, green manure, and cover crops. Cowpea (Vigna unguiculata) is a legume consumed as a high‐quality plant protein source in many parts of the world.High protein and carbohydrate contents with a relatively low fat content and a complementary amino acid pattern to that of cereal grains make cowpea … Cowpea grows rapidly, reaching a height of 19–24 in. Pods are stiff with small seeds. CPMV decorated with E7p72 peptides (high-affinity epidermal growth factor-like domain 7 (EGFL7) binding peptide that specifically targets human endothelial cells) targeted to tumor-associated neovasculature with high specificity as assessed by intravital imaging (Cho et al., 2017). Nutrient content of mature cowpea seed Protein 24.8% Fat 1.9% Fiber 6.3% Carbohydrate 63.6% Thiamine 0.00074% Riboflavin 0.00042% Niacin 0.00281% 7. Further production occurs in the Mediterranean Basin, Southeast Asia, Latin America, and the United States. Cowpea mosaic virus (CPMV; Comovirus, Comoviridae) is the most extensively studied platform for various conjugations and biotechnological applications. The following insecticides* are registered for cowpeas—Adios, Azadirachtin, Bacillus thuringiensis, Capture, Di-Syston, Gaucho, Insecticidal soap, Lorsban, Methaldehyde, Methomyl, Pyrellin, Pyrethrin, Sevin, Success, Telone, and Trilogy. The virus, which contains about 24% RNA, has a sedimentation coefficient of 88.3 S and a diffusion coefficient of 1.50 ± 0.04 × 10 −7 cm 2 /sec at pH 5.0. This chapter provides an overview of its origin, production, biosystematics, cytology, floral biology and hybridization, germplasm resources, and quantitative characters. Summary Other designations. … Efforts are continuing to develop better-performing varieties using conventional breeding procedures, while molecular tools are being developed to facilitate progress in cowpea breeding (Agbicodo et al., 2010). CPMV symptoms and particles (A) Mosaic symptoms on the trifoliate leaves of a CPMV-infected Vigna unguiculata plant (right) compared to an uninfected plant (left). However, this market is fairly well established throughout the South and in California, so it may be possible to sell the crop successfully without having a production contract. The cowpea plant is usually erect and possess ribbed stems and smooth trifoliate leaves which are arranged alternately on the stems. Good protocols for Agrobacterium-mediated transformation (Chaudhury et al., 2007; Popelka, Gollasch, Moore, Molvig, & Higgins, 2006) and also biolistic transformation (Ivo, Nascimento, Vieira, Campos, & Aragao, 2008) of cowpea have been developed and showed stable inheritance of the transgenes. The purified chitinase migrated on SDS-polyacrylamide gel electrophoresis as two closely … [NAIROBI] Applying biochar, a charcoal-like substance made by burning plant waste matter as a fertilizer for growing cowpea could boost the crop’s growth and yield, a study in Ghana has found.. Cowpeas have substantial economic and health importance in Africa, where they provide food for people and livestock, as well as new crops. IITA conserves over 14,000 accessions of cultivated cowpea in its gene bank, and the USDA has duplicates of most of the IITA cowpea lines for safe keeping (Boukar et al., 2013; Dumet et al., 2012). Cowpea is traditionally important as an affordable source of protein and minerals and of cash income in sub-Saharan Africa, especially for small-scale farmers who have limited options for food and cash crops. The plants are thought to be native to West Africa and are widely cultivated in warm regions around the world. All rights reserved. Department of Agricultural and Bio-Environmental Engineering, The Federal Polytechnic, School of Engineering, Ado Ekiti, Ekiti State. However, there are not many reports in literature on the use of wild cowpea relatives for the genetic improvement of cultivated varieties for pest and disease resistance (reviewed in Boukar et al., 2013). These CPMV-based sensors were found to be specific in binding to the cancer cells that are overexpressing these receptors on the cell surface (Brunel et al., 2010; Steinmetz et al., 2011). Mycotaxon, 43:9-20 Bean and cowpea leaves (6 g FW) frozen in liquid nitrogen were used for total RNA extraction . The cowpea (Vigna unguiculata) is an annual herbaceous legume from the genus Vigna. Choice of market class, and approach to narrow or wide rows can affect which variety to choose. They would probably mature too late for double cropping in northern Missouri. The concept of using RNAi construct to silence the CPSMV proteinase cofactor gene and CABMV-CP gene is explored in transgenic cowpea. Overall, dried black-eyed or pink-eyed/purple hull peas can be looked at as another crop to diversify the crop base on a farm. The invention relates to the seeds of cowpea cultivar 951135, to the plants of cowpea 951135 and to methods for producing a cowpea plant produced by crossing the cultivar 951135 with itself or another cowpea variety.
