Path coefficient analysis studies in rice (Oryza sativa L.) for quantitative and qualitative traits

Path coefficient studies were carried out for yield and quality traits in 74 rice genotypes involving hybrids and their parental lines. Grains per panicle, productive tillers per plant and amylose content were significant and positive direct effects on yield at genotypic level. Grains per panicle, productive tillers per plant and amylose content contributed maximum to higher grain yield compared to other characters, thus, selection for these characters helps in selection of superior cross combinations for improvement of yield.
