Correlation and path coefficient analysis was carried out for yield and yield components in 93 rice genotypes involving hybrids and their parental lines. Plant height, productivity per day, filled grains per panicle, days to 50 per cent flowering and panicle weight had a significant positive association with yield and also had a positive direct effect on yield both at the phenotypic and genotypic levels. These traits contributed maximum to higher grain yield compared to other characters, thus, selection for these characters helps in selection of superior cross combinations in hybrid rice.
