Variability Analysis in Determinate F4 Progenies for Yield and it's Attributes in Indian Bean [Lablab purpureus (L.) Sweet]
Agricultural Science Digest - A Research Journal
Indian bean [Lablab purpureus (L.) Sweet] is an important vegetable as well as split pulse crop in India. An attempt was made here to study the genetic variability, correlation and direct and indirect effects through path analysis for yield and yield attributing traits. Methods: Total 52 genotypes were evaluated in randomized block design (RBD) with three replications during early-rabi season, 2018-2019. Observations were recorded on 11 quantitative traits. Result: Significant variation existed
... in all the characters. Higher values of GCV and PCV were observed for pods per raceme, pods per plant and seed yield per plant. High heritability coupled with high genetic advance was observed for racemes per plant, pods per raceme, pods per plant, pod width and seed yield per plant. Seed yield per plant was highly significant and positively correlated at genotypic level with days to maturity, plant height, racemes per plant, pods per raceme, pods per plant and seeds per pod. Path analysis based on genotypic correlation revealed that high positive direct effects on seed yield per plant was registered by pod per raceme followed by racemes per plant, pod length, days to 50% flowering, plant height, pod weight and days to maturity.
