JF - <i>Electronic Journal of Plant Breeding</i> JA - EJPB VL - 6 IS - 4 SE - Research Note DO - UR - https://ejplantbreeding.org/index.php/EJPB/article/view/552 AB -  India is home to a large number of indigenous rice varieties. Sixty indigenous aromatic rice genotypes from different geographical regions of India, were raised at Agriculture Research Farm, BHU, Varanasi during Kharif 2014 to identify variability among them. They were evaluated for seventeen yield and quality characters using D2 analysis, to study the diversity pattern among the genotypes. Based on the analysis, the genotypes were grouped into 8 clusters. Thirteen  genotypes each were grouped under cluster V and VIII, while minimum number of genotype (1) was grouped under cluster II. Maximum inter cluster D2 value was observed between cluster I and VIII (85.56) followed by cluster II and VIII (80.90). The greater the distance between the two clusters indicates wider the genetic diversity between genotypes. The intra cluster distance was maximum in cluster VII (28.10) followed by cluster V (24.12) indicates hybridization involving genotypes within the same clusters may result in good cross combinations. Among the seventeen traits studied, maximum contribution was made by Days to 50% flowering (32.65), Kernel length after cooking (20.07) and amylose content (20.11). Hence, days to 50 percent flowering, Kernel length after cooking and amylose content together contribute 72.83 % towards total divergence. Therefore, these characters may be given importance during selection of parents in hybridization programmes. ER -
