Correlation and path analysis study between yield and yield components in colored pericarp sorghum (Sorghum bicolor (L.) Moench)

Eighty one genotypes including five checks were studied for character association for yield and its components. Correlation study estimates gives some idea as to the relative importance of each of the components to final grain yield, although it is an established fact that nature and magnitude of associations would vary with the composition of the material. In present study, simple correlation co-efficient were estimated at both the phenotypic and genotypic levels in eighty one genotypes. It was observed that the magnitude of association varied among the genotypes. Correlation studies revealed that, grain yield per plant had significant positive association with days to 50% flowering, plant height, number of primaries per panicle, panicle length, panicle width, days to physiological maturity, threshability, fodder yield per plant and non-significant positive association with panicle type, grain color, 100-seed weight point out that the importance of these characters in selection programme for selecting high yielding genotypes in sorghum.
