Title: Genetic variability and heritability of yield and related characters in cowpea (Vigna unguiculata L. Walp.)

Walp.) is a grain legume commonly grown and consumed in many parts of the tropics and subtropics. The general grain yield of cowpea especially in marginal areas is still low and no single variety can be suitable for all growing conditions. Exploiting genetic variability to identify high yielding genotype is one of the strategies used to overcome the complex nature of cowpea breeding. Forty-nine cowpea accessions were tested in 7 x 7 triple lattice design at Haramaya University, Dire Dawa Tony farm with three replications in 2010/11. Analysis of variance revealed significant differences among the forty nine accessions for all the characters studied. High phenotypic and genotypic coefficient of variation, heritability in broad sense and genetic advance estimated for the characters viz., yield per plant, number of pods per plant, and 100-seed weight indicated the scope of improvement of these characters through selection.Read More
