Abstract:

The F2 segregating generation of two crosses viz., Anna (R) 4 x IR 64 Pup 1 and Anna (R) 4 x Samba mahsuri Pup 1 were evaluated for variability parameters and frequency distribution. The results revealed that both the crosses exhibited high PCV and GCV for the traits viz., number of tillers per plant, number of productive tillers per plant, number of filled grains per panicle, shoot P content and single plant yield. The traits viz., plant height, number of tillers per plant, number of productive tillers per plant, number of filled grains per panicle, hundred grain weight, shoot P content, grain P content and single plant yield showed high heritability coupled with high genetic advance as per cent of mean indicating the presence of additive gene effect and selection for these traits may be effective. The trait panicle length and grain P content had negative skewness and selection may be effected to evolve high yielding phosphorous deficient tolerant variety in rice.
