Path coefficient analysis and correlation among grain yield and kernel characters in rice (Oryza sativa L.)

An investigation was carried out using 16 rice genotypes including 11 maintainer lines and 5 varieties for grain yield and kernel characters to understand the association among yield components and their direct and indirect influence on the grain yield. Analysis of variance revealed considerable variability among the genotypes for 13 the characters among 15 characters. The correlation analysis indicated that grain yield was significantly associated with plant height, number of productive tillers per plant, panicle length, leaf area index and number of grains per panicle. Results of path-coefficient analysis revealed that kernel length had the highest positive direct effect on grain yield followed by number of grains per panicle, number of productive tillers per plant and test weight. Hence, selection based on these traits could help to bring simultaneous improvement of yield, yield attributes and kernel characters.
