Variability and association studies in indigenous aromatic rice (Oryza sativa L.)

The variability, correlation and path analysis for yield and quality traits in twenty-five indigenous aromatic rice genotypes were estimated. Highest genetic coefficient of variation was recorded for grain yield plant -1 and number of panicle bearing tillers among yield traits and length/breadth ratio for quality traits. High heritability (broad sense) coupled with high genetic advance was observed for yield plant -1 , number of panicle bearing tillers and number of grains panicle -1 . Number of panicle bearing tillers and days to 50% flowering exhibited highest positive direct effect along with positive association with yield plant -1 . Kernel length after cooking quality showed highest positive direct effect on kernel length.
