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