Abstract:

An experiment was conducted to estimate genetic variability, heritability and genetic advance expressed as per cent of mean in F2 population of two crosses viz., DCS-47-1 × PL-1 and DCS-47-1 × PGCP-12 in cowpea. Analysis of variance revealed significant differences among the segregants tested for all the sixteen characters. High PCV and GVC were observed for number of secondary branches per plant, leaf to stem ratio, number of pods per plant, green fodder yield per plant, green fodder yield per metre row length and stover yield per plant in both the populations. Higher magnitude of broad sense heritability and genetic advance in percentage over mean noticed for secondary branches, days to first flowering, dry matter content, number of pods, number of seeds, pod length, seed yield, green fodder yield per plant as well as per metre row length and stover yield per plant in both F2 populations. These characters might be governed by additive gene action, hence for direct selection for such characters would be helpful in further generations. Besides, a good number of desirable transgressive segregants were also isolated for green fodder yield/ plant and seed yield/plant from both F2 populations.
