Genotypic variability and stability of some grain yield components of Cowpea
The grain yield components of eleven cowpea genotypes were studied in 2006 and 2007 at Abeokuta, Nigeria, to understand the sensitivity of the quantitative traits to heterogeneous environments. The genotypes differ significantly (p ≤ 0.05) in grain yield; the pods/plant and Dfodyld equally differed significantly for the two years. Significant (p ≤ 0.05) genotypic variation in pod length was only in...
