Abstract:
Twenty four genotypes of dolichos bean (Dolichos lablab L.) were evaluated for under All-India Coordinate Research Project on Vegetable Crops, Department of Vegetable Science, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.), during rabi season 2021-22. The range, mean, heritability in broad sense, genetic advance, genetic advance as percentage of mean, phenotypic and genotypic coefficient of variations, correlation and path coefficient were estimated. The studies on variability showed high genotypic as well as phenotypic coefficient of variations for traits viz., pod width (32.10 and 32.71 percent), no. of primary branches per plant (25.10 and 29.09 percent), fresh pod yield per plot (20.95 and 26.28), fresh pod yield per plant (20.52 and 26.26), no. of pods per cluster (21.83 and 25.38 percent) and average weight of pod (21.94 and 23.76 percent). Higher heritability estimates coupled with high genetic advance as percentage of mean were observed for plant height, no. of primary branches per plant, days to first flowering, no. of flowers per inflorescence, days to 50% flowering, inflorescence length, pod length, pod width, no. of pods per cluster, average weight of pod, fresh pod yield per plant and fresh pod yield per plot. Fresh pod yield per plant (1.060) expressed a highest positive direct effect on fresh pod yield per plot followed by days to first flowering (0.249), days to first fruit harvest (0.244) and pod length (0.242).
