With poor quality of irrigation water, salt concentrations in cultivated areas keep increasing, hence preventing cowpea from being cultivated for optimal growth and development. Effects of salinity on crops are severe in semi-arid and arid regions where low rainfall does not allow salt compounds to be leached from soils. Seedling stage is one the most vulnerable stages in plant growth and development...
Cowpea (Vigna unguiculata L. Walp) is a legume consumed for its high protein content. It provides nutrient-dense food opportunities for human consumption. Iron deficiency chlorosis (IDC) manifests as yellowing of the leaves and reduced plant growth, resulting in reduced yield potential. Use of IDC tolerant cowpea cultivars is an efficient method to address this problem. The objectives of this study...
Background Spinach is a useful source of dietary vitamins and mineral elements. Breeding new spinach cultivars with high nutritional value is one of the main goals in spinach breeding programs worldwide, and identification of single nucleotide polymorphism (SNP) markers for mineral element concentrations is necessary to support spinach molecular breeding. The purpose of this study was to conduct a...
Cowpea is a legume widely grown in Africa, North, Central and South America, and Asia. The cowpea plant growth habits consist of erect, semi-prostrate, and prostrate types. Developing a cultivar while considering plant growth habit is essential within a breeding program since the need for a particular growth habit is region-specific, and significantly depends on the end user preference. Some cowpea...
Key message This is the first report on association analysis of salt tolerance and identification of SNP markers associated with salt tolerance in cowpea. Abstract Cowpea (Vigna unguiculata (L.) Walp) is one of the most important cultivated legumes in Africa. The worldwide annual production in cowpea dry seed is 5.4 million metric tons. However, cowpea is unfavorably affected by salinity stress...
Cowpea [Vigna unguiculata (L.) Walp.] is an important legume crop, widely grown in Africa, South America, South Asia, Southeast Asia, and the southern United States. Cowpea is consumed as both fresh vegetable and dry grain, and as an animal feed and fodder, and it is a major dietary protein source that complements cereal-based diet. Cowpea mosaic virus (CPMV) causes a severe yield loss of cowpea in...
Cowpea (Vigna unguiculata (L.) Walp) is a legume of economic importance world-wide, especially in Western Africa, where it is an important part of the population’s diet. The rapidly increasing population growth in Africa requires substantial increase in cowpea production, which can be achieved by expanding land areas for agricultural purposes. In addition, prevalence of soil acidity in Africa constrains...
Cowpea aphid (Aphis craccivora) is a destructive insect pest of cowpea, as well as other legume crops including alfalfa, beans, chickpea, lentils, lupins and peanuts. The utilization of aphid resistance in cowpea breeding is one of the most efficient and environmental friendly methods to control aphids. Using marker-assisted selection will expedite cowpea breeding procedures, but it is limited by...
