Exploiting the Genetic Potential of Cowpea in An Intercropping Complex

In the West African sub-region, intercropping is a critical element in cowpea product profiles. This study aimed to investigate impact of with pearl millet on genetic correlations, heritability, and response selection. Thirty-five genotypes one variety were used create three cropping patterns: sole cowpea, 1:1 (one row cowpea), 2:4 (two rows four cowpea). Split-plot experiments conducted for two years patterns considered as main plots sub-plots. Data captured grain yield (GY), 100 seed weight (Hsdwt), pod (Pdwt), fodder (Fdwt), harvest index (HI). Genotype, pattern, year, genotype-by-cropping pattern interactions significant most traits. Higher heritability predicted advance depicted under rather than intercropped systems. High positive correlations (rg ≥ 0.9) obtained between patterns. Genetic among traits higher intercropping. Path analysis portrayed HI having highest direct effect GY. identified short duration that are stable adapted unique
