Genetic variation for productivity and its related traits in a recombinant inbred lines population of chickpea

Abstract

A recombinant inbred line population of a cross ICCV-2 x JG 62 was evaluated for yield and its component traits. Highly significant variation was observed for yield and other component traits. The RIL population showed high range of expression transcending the limits of parental values for some important traits like seed weight, pods per plant and seed yield per plant. Heritable variation was high in respect of seed weight (92.60) compared to pods per plant (74.10) and seed yield per plant (79.90). High variability followed by high estimates of heritability was observed for pods per plant, seed yield per plant, seed weight, days to 50% flowering, days to pod initiation and plant height. It was therefore concluded that selection for these traits in the material studied would be useful in the genetic improvement of these traits.
