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 to study the genetic variability parameters, correlation coefficient and path coefficient for yield and its attributing traits. The values of PCV for all the traits were found to be more than GCV and very small difference was present in between GCV and PCV revealing little influence of environment for their expression. High heritability accompanied with high genetic advance was observed for the traits thousand grain weight (g), head rice recovery (%), spikelet fertility (%), harvest index (%), number of spikelets/panicle, fertile spikelets/panicle, spikelet density, grain yield /plant (g), panicle weight/plant (g), number of tillers/plant and number of productive tillers/plant. Based on the results from correlation and path coefficient analysis, it is concluded that number of tillers/plant, spikelet fertility and panicle weight/plant showed positive correlation with grain yield and at same time exhibited high positive direct effect towards yield. Therefore, they seem to be primary yield contributing character and thus can be used as direct selection to improve genetic yield potential of rice.
