tailieunhanh - Heritability and genetic advance analysis in rice (Oryza sativa L.) genotypes under aerobic condition

The experiment was conducted in experimental Farm, Regional Research Station, Anand Agricultural University from July to November 2018toestimate the extent of variability present in rice genotypes with respect to yield and its component traits. The estimates of genotypic and phenotypic variances for the characters like plant height, effective tillers per plant, number of grains per panicle, grain yield per plant, straw yield per plant, harvest index and 1000 grain weight, genotypic variance contributed larger in phenotypic variance. | Heritability and genetic advance analysis in rice (Oryza sativa L.) genotypes under aerobic condition (2020) 9(3): 1196-1204 International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 3 (2020) Journal homepage: Original Research Article Heritability and Genetic Advance Analysis in Rice (Oryza sativa L.)

Parmar Main Rice Research Station, Anand Agricultural University, Nawagam - 387540, Gujarat, India *Corresponding author ABSTRACT The experiment was conducted in experimental Farm, Regional Research Keywords Station, Anand Agricultural University from July to November 1,000-grain weight, 2018toestimate the extent of variability present in rice genotypes with Variability, respect to yield and its component traits. The estimates of genotypic and Genotypic phenotypic variances for the characters like plant height, effective tillers Coefficient of variation, per plant, number of grains per panicle, grain yield per plant, straw yield Heritability per plant, harvest index and 1000 grain weight, genotypic variance contributed larger in phenotypic variance. The highest genotypic coefficient Article Info of variation (GCV) and phenotypic coefficient of variation (PCV) were Accepted: observed for straw yield per plant (, ), followed by harvest 05 February 2020 Available Online: index (, ) and grain yield per plant (, ). High 10 March 2020 heritability coupled with high genetic advance were observed for plant height, number of grains per panicle and straw yield per plant. Introduction depleting water resource demands others alternative approaches without compromising Rice (Oryza sativa L.) is the most valuable the productivity. Aerobic cultivation of rice is crop in the world and
