Variability studies revealed that considerable amount of variability exist in the F2 population of rice cross CB 08504 × Prasanna through high values of PCV and GCV for characters like number of filled grains per panicle, spikelet fertility percentage and single plant yield. High PCV and moderate GCV was observed for number of productive tillers per plant while moderate PCV and GCV was recorded for days to first flowering and harvest index. High heritability coupled with high genetic advance as percent of mean was observed for the characters namely number of filled grains per panicle, number of productive tillers per plant, spikelet fertility percentage and single plant yield in the F2 population. The traits days to first flowering, number of productive tillers per plant, panicle length, number of filled grains per panicle, spikelet fertility percentage and harvest index were showing significant and positive correlation with single plant yield. The F2 population of CB 08504 × Prasanna performed better for earliness, yield and yield associated traits and could be utilised in future breeding programs to meet the increasing demand of rice. |
