An investigation was carried out at ZARS, VC Farm, Mandya during 2015 to study the variability produced in two F2 populations of rice viz., ‘Rajamudi × BR-2655’ and ‘Rathnachoodi × BR-2655’ with 500 single plants to estimate the variability, heritability, genetic advance and genetic advance as percentage. The results showed that PCV values in general were higher than GCV for various characters studied. The high PCV and GCV values was obtained for grain yield per plant and low PCV and GCV was observed for thousand grain weight and panicle length. The small difference observed between GCV and PCV indicate the presence of high genetic variability for the traits which may facilitate selection. The traits Plant height, Spikelet fertility, harvest index and grain yield per plant had high heritability along with high genetic advance as per cent of mean indicate that these characters attributable to additive gene effects which are fixable revealing that improvement in these characters would be possible through direct selection.
