“…The high value of GCV and PCV was recorded only for grain yield per plant 24.49 and 25.96, respectively. These results are in agreement with the findings of Dhanwani et al [2], Chamar et al [3], Noatia et al [4] and Singh et al [5].…”

“…The low estimates of GCV and PCV were reported in days to 50% flowering (GCV 4.89, PCV 5.23), plant height (GCV 7.19, PCV 8.76) and panicle length (GCV 4.17, PCV 7.74). Similar findings have been reported by Noatia et al [4] and Sudeepthi et al [7] for the panicle length, days to 50 % flowering, by Donkor et al [8] for days to 50% flowering and plant height.…”

The research work was executed Research cum Instructional Farm, Genetics and Plant Breeding department of IGKV Raipur (C.G.) during kharif 2021. The research material under research comprised of 50 rice germplasm lines including two checks namely Mahamaya and Rajeshwari, which were tested in RBD with two replications. The observation of research investigation were recorded for total eight characters viz. Days to 50% flowering, Number of tillers per plant, Panicle length(cm), Plant height(cm), 1000seed weight(g), Grain yield per plant(g), Biological yield per plant(g), Harvest index(%). The analysis of variance showed that there was a highly significant variation in genotypes for all of the studied characters. A small difference between PCV and GCV suggests that the environment has little impact on the concerning traits. The number of tillers per plant, 1000 seed weight, grain yield per plant, biological yield per plant and harvest index had high heritability along with high genetic advance as a percent of mean indicates that the heritability is most likely caused by additive gene action and selection may be effective.

“…The direct effects of days to 50 % flowering, numbers of tillers per plant, plant height, panicle length and 1000 seed weight were observed to be negligible, but the characters plant height, panicle length and 1000 seed weight showed significant positive correlation with grain yield per plant via indirect effects. This was in accordance with Noatia et al (2021) [10] . Similar results were reported by Sreedhar et al (2019) [13] and Prasad et al (2017) [11] for days to 50 % flowering, plant height and 1000 seed weight, by Begum et al (2021) [3] for days to 50 % flowering, plant height, panicle length, 1000 seed weight, by Pravalika et al (2021) [12] for biological yield per plant and harvest index, by Kumar et al…”

The entitled research work "Association analysis for yield and its contributing traits in rice (Oryza sativa L.)" was executed Research cum Instructional Farm, Department of Genetics and Plant Breeding, IGKV Raipur (C.G.) during kharif 2021. The research material under research comprised of 50 rice germplasm lines including two checks namely Mahamaya and Rajeshwari, which were tested in RBD with two replications The observation of research investigation were recorded for total 8 characters viz. Days to 50% flowering, Number of tillers per plant, Panicle length (cm), Plant height (cm), 1000 seed weight (g), Grain yield per plant (g), Biological yield per plant (g), Harvest index (%). Positive significant correlation was showed Grain yield per plant with Number of tillers per plant, 1000seed weight, biological yield per plant. These characters would be beneficial for increasing yield and choosing superior genotypes among rice cultivars. Positive direct effect on Grain yield per plant showed by the Harvest index, biological yield per plant, Panicle length, Days to 50% flowering, Number of tillers per plant, 1000seed weight revealed true relationship between them and direct selection for these traits would be beneficial for increasing yield.

Genetic variability is crucial for effective selection and breeding in rice improvement programs. This study assesses the genetic variability parameters for yield and its contributing traits in rice hybrids using 25 cross combinations, including parents, and checks. was studied at IGKV Raipur, Chhattisgarh for 13 characteristics. In this analysis depicts higher estimates of GCV and PCV observed for grain yield per plant, biological yield per plant, total tillers per plant, and effective tillers per plant. The high value of Phenotypic coefficient of variance than Genotypic coefficient of variance indicates influence of environment. Moderate values of GCV and PCV were noticed in plant height, harvest index, 1000 seed weight, number of filled spikelets per panicle and the total number of spikelets per panicle. Lower estimates were recorded for spikelet fertility (%), days to 50% flowering, and days to maturity. The PCV was generally higher than the GCV, and showed less influence of environment for the expression of yield traits. High heritability was observed for traits like biological yield per plant, total tillers per plant, total number of spikelets per panicle, grain yield per plant, number of filled spikelets per panicle, 1000 seed weight, effective tillers per plant, spikelet fertility (%), plant height, harvest index, days to 50% flowering, panicle length, and days to maturity. Genetic advance as a percentage of mean was also found higher for grain yield per plant, biological yield per plant, total tillers per plant, effective tillers per plant, plant height, harvest index, 1000 seed weight, number of filled spikelets per panicle, and total number of spikelets per panicle. Moderate genetic advance was observed for panicle length and spikelet fertility (%). Lower genetic advance was observed for days to 50% flowering and days to maturity. Traits with high heritability and high genetic advance as a percentage of mean are likely controlled by additive gene action, making them suitable for selection and genetic improvement. Traits with high heritability but moderate genetic advance may involve both additive and non-additive gene actions. Recommending these potential lines for genetic improvement through selection. The findings provide valuable insights for breeders aiming to enhance crop performance through targeted trait selection and breeding strategies.
