Delineating the Association of Component Traits and their Effects on Yield in Elite Rice (Oryza sativa L.) Genotypes of Telangana and Andhra Pradesh

The current study was conducted at Seed Research and Technology Center (SRTC), Professor Jayashankar Telangana State Agricultural University, Hyderabad, state, India to understand traits association with yield components their direct indirect influence on seed/grain during the kharif season (July November) 2018–19. Eighteen elite rice genotypes were evaluated for eight attributing in randomized complete block design (RCBD) three replications. Correlation among reveals that, genotypic correlation coefficients slightly higher than phenotypic most showed of genetic composition lines’ expression. Highly significant positive strong observed days maturity 50% flowering (0.8955 0.8230), while moderate productive tillers plant-1 panicle length (0.5744 0.3571) level respectively. However, depicted a thousand seed weight (0.4048 0.3895), very low number (0.0579 0.0524) levels. results path analysis revealed that has high (0.3286*) coefficient value (0.3198) indicates effects (0.2252) shows impact yield. These could be used as selection criteria improve grain quality breeding programs.
