Abstract
The present investigation was carried out for correlation and path coefficient analysis using 32 rabi sorghumhybrid parents including maintainers (B) and restorer (R) lines for grain yield and its attributes. The experimental materialwas evaluated during rabi season 2021-22 at Regional Agricultural Research Station, Vijayapur in randomized block designwith two replications. The character association studies revealed that grain yield per plant was found to be significantly andpositively correlated with days to 50% flowering, plant height, panicle breadth, panicle weight, harvest index, panicleharvest index, seed set percentage and grain number per plant both at genotypic and phenotypic level. Path analysisrevealed that characters such as panicle weight, panicle harvest index, harvest index, fodder yield per plant, days to 50%flowering and SPAD at physiological maturity showed a positive direct effect on grain yield per plant. These traits can beconsidered as principal yield determining components and it is suggested to use these as indirect selection criteria for B andR-line improvement.
