Abstract

The present investigation was conducted during Kharif, 2014 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 experiment included the 28 diverse genotypes of rice bean along with three checks viz., PRR-1, PRR-2 and BRS-1 were evaluated in Randomized Complete Block Design. The characters studied were days to 50 % flowering, days to maturity, plant height, stem thickness, number of primary branches per plant, leaflet size , number of pods per plant, number of seeds per pod, pod length,100 seed weight and seed yield per plant. The twenty eight genotypes of rice bean were grouped into six clusters irrespective of geographical diversity, indicating no parallelism between geographic and genetic diversity. The cluster pairs exhibiting very high inter-cluster distances were cluster IV and V, cluster II and IV, cluster I and cluster IV, cluster III and IV. Considering cluster mean and genetic distance the crossing of entry of clusters IV with entries of cluster V and those genotypes of cluster II, I and III with the entries of cluster IV would be fruitful for obtaining transgrassive segregants for developing high yielding and better quality rice bean varieties.
