Correlation between yield and yield components in rice Coryza sativa L.)

The correlation coefficients of yield with seven other yield components and the association among themselves were worked out in.the F₄ and F₅ generations of the rice cross Zhenshan 97 A x IR 50. Except panicle exsertion all other traits showed positive and significant association with yield. Among the yield components, days to 50 per cent flowering, number of productive tiners per plant, panicle length, number of grains per panicle and 100 grain weight were found to be dependable attributes on which the selection would be concentrated for enhancing the yield.
