Abstract:

An experiment was conducted with 23 F2 generation genotypes in randomized block design with three replication rabi season of 2017-18 at Research and Education farm, Department of Agriculture Botany, College of Agriculture, Dapoli. The estimates of phenotypic, genotypic and environmental variances revealed that, in general phenotypic variances for all the characters studied were higher than genotypic variances. Phenotypic coefficient of variation was greater than the genotypic coefficient of variation for all the characters for present study. The high phenotypic and genotypic coefficient of variation was observed for seed yield per plant, number of pods per plant, number of clusters per plant and number of primary branches per plant, while lowest GCV and PCV was observed for days to first flowering and days to maturity. High heritability with high genetic advance as percentage of mean was observed for seed yield per plant, number of pods per plant, plant height, number of primary branches per plant, hundred seed weight and harvest index. It indicates additive gene action and made it suitable for direct selection.
