Abstract

The current investigation was carried out in the year 2021-22 at Dryland Agriculture Research Station (DARS), Budgam. The experiment was laid out in randomized complete block design with three replications in field and completely randomized design (CRD) in vitro conditions for evaluating different traits of genotypes. DUS characterization was conducted as per the DUS testing guidelines by Protection of Plant Varieties and Farmers Act, Authority, Descriptors for rajmash (Phaseolus vulgaris L.) GOI, New Delhi [reproduced from Plant Variety Journal of India. Vol. 1(1), 2007].

The observations were recorded on 18 DUS characters including morphological and quality attributes and physiological characters. For all the features studied, the analysis of variance for morpho-physiological and qualitative attributes found significant differences, providing adequate chance to select the genotypes with desired qualities. DUS traits were examined in accordance with the descriptor, “state” and “code” provided for each character.

The observed range of variation were recorded for different traits for different genotypes. Cluster analysis for morphological, maturity, yield and quality characteristics arranged the rajmash genotypes into 11 clusters, as per Mahalanobis D2 analysis using Tocher’s method with cluster III having the maximum number of genotypes (8), followed by cluster I, II, IV and V with 6 genotypes, 2 genotypes were grouped in cluster VII and XI and the remaining clusters with 1 genotype each. Diversity analysis showed grouping of genotypes in 11 clusters, which will help in selection of genetically divergent parents for exploitation in hybridization programme and would constitute an essential gene pool for future breeding programme.
