Abstract:

Association studies among seven traits were studied in 40 genotypes during kharif, 2015 at Agricultural Research Station, Kunaram, Telangana State. In general, genotypic correlation coefficients were higher than the corresponding phenotypic correlation coefficients suggesting that strong genetic association among the yield and yield components of rice. Correlation coefficient analysis showed that number of productive tillers per m2 and 1000-grain weight exhibited significant positive correlation with yield at both genotypic and phenotypic levels. Significant negative correlation was observed between number of filled grains per panicle and yield. Path coefficient analysis revealed that positive direct effect of number of productive tillers per m2 and days to 50% flowering on grain yield at both genotypic and phenotypic levels.
