Genetic variability, heritability an character association in induced mutants of basmati rice (Oryza Sativa L.)

Twenty-four Basmati rice genotypes including three checks viz., Taraori Basmati, Pusa BasmatiI and Pusa Sugandha-2 were evaluated Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during Kharif, 2002. The range of variation varied widely in case of number of grain/panicle followed by plant height. The traits viz., days to flowering, grain yield/plant, harvest index and spikelet fertility showed higher values of heritability whereas, characters, viz., panicle length, grain length, grain breadth and secondary branches/panicle showed moderate values of heritability. The highly significant, positive correlation was observed between grain length and LIB ratio, secondary branches/panicle and number of grains/panicle, harvest index and panicle length with grain yield/plant and days to flowering with days to maturity both at phenotypic and genotypic level.
