Abstract:
The current investigation was performed at Seed Breeding Farm, Department of Plant Breeding and Genetics, College of Agriculture, JNKVV, Jabalpur, during Kharif 2022. 104 rice genotypes were planted in Randomized Complete Block design with three replications. The present study was initiated to obtain the promising rice hybrids in respect of various yield and grain quality traits in rice hybrids. High GCV and PCV was observed for number of tillers/ plants, number of effective tillers/plants, panicle weight per plant, plant weight, biological yield/ plant, sterile spikelet/panicle, fertile spikelets /panicle, total no. of spikelet, spikelet density %, harvest index, panicle index, and grain yield/ plant. Grain yield per plant shared positive significant correlation with biological yield/plant and panicle weight/plant. The genotypes of cluster III and cluster VI showed higher inter cluster distance, hence the parental lines fell in these clusters may be utilized for broaden the genetic base of rice. On the basis of PCA ranking for yield attributing five genotypes viz., R 671 ×NPT 29, Kranti × JNPT 1058, Kranti × WGL -14, Shyamla x IR 64 and 29A× P3123 crosses were found superior both for yield and attributing traits.
