Genetic diversity analysis in JNPT lines of rice (Oryza sativa L.)
Author(s): Shivangi Rahangdale and Yogendra Singh
Abstract: In present study, sixty-seven JNPT (Jawahar New Plant Type) lines were evaluated for twenty-eight morphological and quality traits planted in Randomized Complete Block Design with three replications. The experiment was conducted during kharif seasons of 2018 at Seed Breeding Farm, Department of Plant Breeding and Genetics, College of Agriculture, JNKVV, Jabalpur (M.P.), India. Observations were recorded on the basis of middle five random competitive plants selected from each line in every replication for yield and quality traits. Considerable genetic variability was exhibited by all the yield and quality traits under study. The genotypes of cluster VIII and IX showed higher (19816.1) inter cluster distance followed by cluster IV and VIII (12414.7). Hence genotypes of these clusters may be crossed to broaden the genetic base of rice. Intra cluster distance has been found the highest of cluster V hence, the hybridization among the genotypes of cluster V may also result superior recombinants. The results of this study suggested further hybridization programme should be planned involving the diverse genotype viz. JNPT-1065-3, JNPT-1066-52, JNPT-1065-1, JNPT-1065-2 and JNPT-1068-65 present in Cluster IV, Cluster V, Cluster VII and Cluster VIII on the basis of their greater inter-cluster distances and higher cluster mean values for the yield and quality attributing character.
