Abstract:
Investigated were the relationships between different yield features and the pattern of influences on rice grain yield. In order to establish selection criteria for a greater grain yield, it is crucial to evaluate the direct and indirect impacts of different features on yield. A randomized complete block design was used to examine 23 rice landrace genotypes. According to the results of the character association analysis, there is a substantial strong correlation between the number of productive tillers per plant, the harvest index, the number of fertile spikelets per panicle, and the biological yield. Path coefficient analysis expressed that number of fertile spikelets per panicle, panicle length, days to 50% flowering, number of tillers per plant, thousand grain weight and biological yield were showing high positive effect on the grain yield per plant. For accurate selection, it is necessary to validate important yield- and quality-related factors by molecular characterization of the rice genotypes.
