Abstract:
Association studies are one of the important biometrical tools for formulating a selection index as it reveals the strength of relationship among the group of characters. Correlation analysis and path coefficient analysis was carried out for yield and component traits in 10 rice genotypes involving three checks. Panicle length, grains per panicle and number of productive tillers per plant exhibited positive and significant association with single plant yield. Hence, selection for these traits will improve single plant yield.
