Abstract:

An investigation was carried out with twenty six colored rice (Oryza sativa L.) genotypes to study the genetic divergence using D2 statistics. Based on 26 yield and quality traits, these genotypes were grouped into six clusters. Among these six clusters, cluster I possessed more number of genotypes (11) followed by cluster II with 8 genotypes and cluster III with 3 genotypes. Cluster II recorded maximum intra cluster distance, while highest inter cluster distance was observed between cluster V and cluster VI. Cluster II had highest mean value for grain yield/plant whereas the genotypes grouped in cluster III exhibited highest mean value for panicle length, number of filled grains/panicle and total number of grains/panicle. Cluster V was characterized by highest mean value for ear bearing tillers/plant and test weight among yield components and total starch content, Zn content & slowly digestible starch among quality parameters. Cluster VI manifested highest mean value for most of physic-chemical and biochemical quality traits studied viz., water uptake, volume expansion ratio, length/breadth ratio, total phenol content, total antioxidant activity, flavonoid content and Fe content. Hybridization among genotypes from cluster V and VI, cluster I and VI followed by cluster II and VI which had maximum inter cluster distances may result in maximum genetic improvement of yield and desirable quality traits of colored rice.
