Abstract:
The present investigation was executed at Main Experiment Station of Department of Vegetable Science, Acharya Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj), Ayodhya (U.P.) during Rabi 2019-20, to estimate the genetic variability among the genotypes, to work out the heritability in broad sense and genetic advance in percent of mean, to estimate correlation coefficient among the growth and yield traits, to work out the path coefficient analysis for different traits and to estimate the genetic divergence D2 among the genotypes for various traits. Experimental material for the study consisted of 72 genotypes including 3 checks (Hisar Sonali, P.E.B. and NDM-1). The experiment was conducted in Augmented Block Design in 6 blocks (12 genotypes + 3 checks in each block). Observations were recorded on 11 quantitative traits viz. days to 50% flowering, plant height, primary branches per plant, secondary branches per plant, days to maturity, pods per plant, length of pods, seeds per pod, 1000 seed weight (g), seed yield per plant (g) and seed yield q/ha. The analysis of variance for the design of experiment indicated highly significant differences among the genotypes for all the characters. Based on mean performance of seed yield and yield components, the genotypes NDM-97 followed by NDM-116, NDM-1, NDM-37, NDM-137, NDM-20, NDM-57, NDM-76, NDM-14 and NDM-132 were identified as most promising genotypes for yield and major component traits. High magnitudes of variability were observed for length of pod and primary branches per plant.
