Abstract

Background: 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]. Methods: 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. Result: 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.

雨养条件下拉吉马什（Phaseolus vulgare L.）基因型形态生理特征的 DUS 鉴定

背景：本次调查于 2021-22 年在布加姆旱地农业研究站（DARS）进行。实验采用随机整群设计，田间三次重复，体外完全随机设计（CRD），以评估基因型的不同性状。DUS 表征是根据《植物品种和农民保护法》（Protection of Plant Varieties and Farmers Act, Authority, Descriptors for rajmash (Phaseolus vulgaris L.) GOI, New Delhi）的 DUS 测试指南进行的[转载自《印度植物品种杂志》，第 1 卷（1），2007 年]。方法：对 18 个 DUS 特征进行了观察记录，包括形态特征、品质特征和生理特征。对于所研究的所有特征，形态-生理和质量属性的方差分析都发现了显著差异，这为选择具有所需质量的基因型提供了充分的机会。根据为每个特征提供的描述符、"状态 "和 "代码 "对 DUS 特征进行了研究。结果记录了不同基因型不同性状的观测变异范围。形态、成熟度、产量和品质特征的聚类分析根据马哈拉诺比斯 D2 分析法（采用托歇尔方法）将 rajmash 基因型分为 11 个聚类，其中聚类 III 的基因型数量最多（8 个），其次是聚类 I、II、IV 和 V，有 6 个基因型，2 个基因型被归入聚类 VII 和 XI，其余聚类各有 1 个基因型。多样性分析表明，基因型分为 11 个群组，这将有助于在杂交计划中选择基因不同的亲本进行利用，并将构成未来育种计划的重要基因库。
