Abstract:

The panel comprises of landraces, improved varieties, interspecific derivatives (Oryza glaberrima× Oryza sativa), aromatic and japonica rice etc. were evaluated during Kharif 2019 used for studying genetic variability, heritability and genetic advance for yield and its related traits in rice. The analysis of variance of 12 different characters of 30 rice genotypes showed differences among the genotypes which revealed that there was genetic variation among the genotypes studied. Phenotypic coefficient of variance was found higher than genotypic coefficient of variance for all studied traits indicate the environmental influence on the expression of these traits. Among the studied traits broad sense heritability ranged from 47.00% (productive tillers) to 94.50% (grain width). The characters plant height, filled grains, total grains, grain length, grain width and grain ratio have high genetic advance as per cent of mean along with high heritability. High heritability with high genetic advance as per cent of mean indicates that these characters are largely controlled by additive gene action would be effective for selecting superior varieties.
