Abstract

The present investigation was carried out to study gene action and pattern of inheritance of different traits in cowpea. Two different F3 segregating generation of crosses viz., VBN-1 × RC-19 and KBC-9 × PGCP-6 were studied during summer 2021 using augmented random block design at College of Agriculture, Kalaburagi. Data were recorded on 10 different quantitative traits. Transgressive segregants with values exceeding the better parent were observed in both the F2:3 populations for seed yield. In both the populations, negative skewness was observed for days to initiation of flowering, days to physiological maturity and number of pods/plant whereas test weight exhibited positive skewness suggesting a mild and intense selection would be sufficient to gain maximum genetic-gain in negatively and positively skewed traits, respectively. In both the F2:3 populations, positive kurtosis was observed for number of branches / plant, test weight and dry matter content/plant indicating that these traits are governed by fewer numbers of genes.
