Abstract: The present investigation was conducted during Kharif, 2015 at Research Block, Department of Crop Improvement, V. C. S. G. Uttarakhand University of Horticulture and Forestry, College of Forestry, Ranichauri Campus, Tehri Garhwal, Uttarakhand. The 34 diverse genotypes of rice bean including four checks varieties viz., PRR-1, PRR-2, and RBL-1and RBL-6 were evaluated in Augmented Design with four replications. Observation were recorded for field and seed quality parameters. Field parameters were recorded for days to 50 per cent flowering, days to maturity, plant height (cm), pod length (cm), number of pods per plant, number of primary branches, number of seeds per pod, 100 seed weight (g) , seed yield per plant (g) and number of clusters per plant. The seed quality parameters were recorded for speed of germination (%), standard germination (%), root length (cm), shoot length (cm), seedling fresh weight (g), seedling dry weight (g), moisture content (%) and accelerated ageing test. The data was analyzed for estimation of mean, range, coefficients of variation, heritability and genetic advance, correlation coefficients. The genotypes RBL-1, PRR-1, IC-341986 and PRR-2 exhibiting high mean performance for seed yield and their component. High magnitudes of phenotypic and genotypic coefficient of variation were noticed for plant height, 100 seed weight and number of pods per plant. High estimates of heritability coupled with high genetic advance as per cent of mean were observed for clusters per plant, 100 seed weight, plant height and pods per plant. Seed per pod exhibited very strong positive association with pod length, pods per plant, clusters per plant and plant height at phenotypic and genotypic level. From this study it is suggested that genotypes viz RBL-1, PRR-1, IC-341986 and PRR-2 can be utilized for improving the yield of rice bean genotypes.
