“…Such traits could be improved through selection in the advanced generations. These results are in accordance with Lingaiah et al (2018) for plant height and thousand seed weight, kalaiselvan et al (2019) and Behera et al (2018) for flag leaf length. Low PCV and GCV were observed for days to first flowering, panicle length and grain L:B ratio.…”

“…Low heritability and GAM was noted in grain L: B ratio and single plant yield. This result was in compliance with Behera et al (2018) Correlation studies provide breeder a wide knowledge about the association of characters, which aids in the selection of elite genotype. Grain yield is a complex trait largely affected by the contributing traits.…”

“…High heritability and moderate genetic advance as per cent of mean was observed in panicle length. This was in fulfilment with Singh et al (2019) and Behera et al (2018). High heritability and moderate GAM is the outcome of both additive and non additive gene action for the trait which can be improved by recurrent selection (Dhurai et al, 2014).…”

An experiment was performed to analyse the variability parameters and frequency distribution properties in F 2 population of CBMAS 14065 x Mappillai Samba for grain yield and its associated parameters. The estimated genetic parameters showed, slightly higher PCV than GCV reflecting the influence of environment. High GCV, high PCV, high heritability along with high genetic advance as per cent of mean was observed in the number of filled grains per panicle suggests the additive gene action which is important for selection. The parameters like plant height, the number of productive tillers per plant, panicle length, the number of filled grains per panicle and thousand grain weight showed a significant positive correlation with single plant yield. Significant positive skewness were observed for the number of productive tillers and grain L:B ratio which helps in fixing the selection criterias and benefits the improvement of traits in F 2 generation.

“…The traits plant height (18.78%, 18.68%) and days to 50% flowering (10.73%, 10.65%) showed moderate PCV and GCV. These findings were in agreement with Akter et al, (2018) for plant height and Behera et al, (2018) for days to 50% flowering.…”

“…The number of panicle and secondary branches per panicle exhibited moderate GCV and high PCV. Similar results were reported for flag leaf area (Saha et al, 2019), the number of spikelets (Saha et al, 2019), the number of grain (Yadav et al, 2018), test weight (Chandramohan et al, 2016), grain yield (Bhati et al, 2015;Mamata et al, 2018;Keerthiraj and Biju, 2020), plant height (Manjunatha et al, 2017;Pragnya et al, 2018), days to flowering (Behera et al, 2018), length of panicle (Pragnya et al, 2018). The large difference between PCV and GCV values for the number of panicles, flag leaf area, the number of secondary branches per panicle, spikelet fertility and seed yield is due to the greater contribution of the environment in the expression of these characters.…”

Twenty-six diverse genotypes were cultivated for two consecutive warm wet seasons of 2015 and 2016 to study genetic variation and the cause-effect relationship of different quantitative characters on seed yield in rice. The genotypes showed significant variation for all the characters. Genotypic and phenotypic coefficients of variation were high for the flag leaf area, spikelet number, grain number, test weight and grain yield, and moderate for plant height, days to flowering, the number of panicle and primary branches per panicle. Heritability was high for days to flowering, plant height and test weight. Genetic advance as per cent of mean was very high for test weight and grain yield, moderate for plant height, flag leaf area and the number of grains, and low for spikelet fertility (%). Genotypic and phenotypic correlations of seed yield with plant height, flag leaf area, days to flowering, the number of primary and secondary branches per panicle, the number of spikelets and filled grains per panicle, spikelet fertility (%) and test weight were significant and positive. Genotypic path analysis indicated that direct selection for test weight, the number of primary and secondary branches per panicle in a positive direction with restricted selection for panicle number and spikelet fertility would increase the grain yield of rice in the population.
