Abstract:
The present study was undertaken to determine the relationship between grain yield and yield related traits in 40 long duration rice genotypes for 15 quantitative traits. The correlation study revealed that yield per hectare (q/ha) had strong positive association with tillers per hill, biological yield (q/ha), harvest index (%), spikelet fertility (%) and 1000 grain weight (g). The path coefficient analysis between yield per hectare (q/ha) as dependent variable and its related traits revealed that biological yield (q/ha), harvest index (%), 1000 grain weight (g), main panicle length (cm) showed high positive direct effect. Hence selection of these traits should be beneficial for improvement of grain yield in long duration rice genotypes.
