Abstract:
Twenty two rice varieties were transplanted in RBD with three replications during 2018-19 at Rice Research farm, RPCAU, Pusa, Samastipur, Bihar to study the genetic variability, heritability and genetic advance for yield and its components. Highly significant differences for almost the characters were observed among twenty two rice varieties under studied. Higher numerical values of phenotypic variances and co-variances with respect to its genotypic counterpart were recorded for all the traits indicating greater environmental influence on these traits for total variation. days to 50% flowering, days to maturity, length of leaf blade, 1000 grain weight, grain length, grain width, decorticated grain length, decorticated grain width and grain yield per plant showed high heritability coupled with high genetic advance as per cent of mean, indicating the preponderance of additive gene action. These characters may be subjected to any single plant selection scheme for exploiting fixable genetic variance. Hence, direct selection for these characters may be done for future improvement of genotypes.
