TAILIEUCHUNG - Studies on character association and path coefficient analysis for anaerobic germination traits, yield and its contributing characters in rice (Oryza sativa L.)

In the present investigation cause of association and direct and indirect effects were estimated between anaerobic germination traits, yield and its contributing traits in twenty five hybrids, along with their ten parents and three checks of rice (Oryza sativa L.). Single plant yield registered positive significant association with number of tillers per hill, number of productive tillers per hill, panicle length, spikelet fertility, number of grains per panicle and 1000-grain weight indicating that these characters were important for yield improvement. Path coefficient analysis revealed that number of number of grains per panicle exserted the highest positive direct effect on grain yield followed by plant height, panicle length, spikelet fertility, anaerobic germination percentage, number of productive tillers per hill, seedling length and number of tillers per hill indicating that the selection for these characters was likely to bring about an overall improvement in single plant yield directly. | Studies on character association and path coefficient analysis for anaerobic germination traits, yield and its contributing characters in rice (Oryza sativa L.)
