Abstract:

The experimental was carried out at Indian Institute of Rice Research Farm, ICRISAT, Patencheru, Hyderabad, Telangana, India, during Rabi, 2014-2015 in order to estimate genetic variability, heritability and genetic advance in two hundred genotypes of rice. Analysis of variance revealed highly significant differences among the genotypes for all the characters indicating sufficient variability existed in the present material selected for the study. Environmental influence was very meagre on the expression of all the characters as there is a narrow difference between genotypic and phenotypic coefficients of variation. Genotypic and phenotypic coefficients of variability were high for single plant yield, number of grains per panicle, number of tillers per hill, pollen viability and spikelet fertility. The characters viz., spikelet fertility, plant height, single plant yield, number of grains per panicle, number of tillers per hill, pollen viability, number of productive tillers per hill, panicle length and 1000 grain weight exhibited high heritability estimates coupled with high genetic advance as per cent of mean which suggested that these traits were amenable for further improvement by following simple selection methods.
