Genetic variability and resistance of cultivars of cowpea [Vigna unguiculata (L.) Walp] to cowpea weevil (Callosobruchus maculatus Fabr.).
The cowpea weevil (Callosobruchus maculatus Fabr.) is the most destructive pest of the cowpea bean; it reduces seed quality. To control this pest, resistance testing combined with genetic analysis using molecular markers has been widely applied in research. Among the markers that show reliable results, the inter-simple sequence repeats (ISSRs) (microsatellites) are noteworthy. This study was pe...
متن کاملVarietal Susceptibility Of Cowpea (Vigna Unguiculata L.) To The Storage Beetle, Callosobruchus Maculatus F. (Coleoptera: Bruchidae)
Twenty-two cowpea genotypes, comprising eighteen elite lines from the CSIR-Savanna Agricultural Research Institute, and three improved cultivars from the International Institute of Tropical Agriculture were evaluated for their susceptibility to infestation and damage by the storage beetle, Callosobruchus maculatus F. The assessment of their relative susceptibilities was based on oviposition, me...
متن کاملVarietal Differences in Physical Characteristics and Proximate Composition of Cowpea (Vigna unguiculata)
Twenty-eight varieties of cowpea seeds from Nigeria and USA origins showed significant variation in physical characteristics and proximate composition. Seed size dimensions namely; seed length, width and thickness had range values of 6-10mm, 4-7mm and 3-5mm, respectively. Seed hydration index had values between 95-137; 100seed weight ranged between 11-26g and seed hardness recorded values betwe...
متن کاملRecent advances in cowpea [Vigna unguiculata (L
After decades of research on cowpea, significant amount of omics datasets are available and useful in understanding the genetic relationship between Vigna unguiculata ssp. unguiculata and other species belonging to the same genus as well as its genetic variation. Besides, the development of genetic map allowed the chromosome localization of molecular markers associated with disease resistance, ...
متن کاملIsolation and characterization of starches from two cowpea (Vigna unguiculata) cultivars
This study was conducted to evaluate and compare the gross chemical compositions and functional properties of starches derived from two cultivars of cowpea. White cowpea starch (WCS) and brown cowpea starch (BCS) were isolated from their respective seeds. The starch yield (40.00%) with its residual protein content (0.09%) from white cowpea seeds was higher than that obtained from brown cowpea s...
