ABSTRACT

Heritability and genetic advance were studied in three New Plant Type (NPT) based crosses of rice for thirteen characters in two environments of normal and high dose of nitrogen. Significant genetic variability was observed between the two filial generations and their parents of three crosses of rice for all the characters under study. High heritability estimates coupled with high genetic advance as per cent of mean was seen in all the crosses for days to fifty per cent flowering, days to maturity, plant height, panicle length, L : B ratio and 1000 grain weight, while high heritability with moderate genetic advance was seen in average grain length and grain breadth. Spikelets per panicle and filled grains per panicle had moderate heritability and high genetic advance. Productive tillers per plant, spikelet sterility and grain yield per plant showed low to moderate heritability coupled with low to moderate genetic advance as per cent mean.
