Abstract:
The field experiment consists of 26 R lines evaluated at Sorghum Research station, VNMKV, Parbhani to study genetic variability, correlation and path analysis for yield and yield attributing traits. The experiment was conducted by using randomized block design with 3 replications during kharif 2020. The analysis of variance showed high significant differences among genotypes indicating the presence of sufficient variability. High estimates of GCV and PCV was observed for grain yield per plant and fodder yield per plant. Number of primaries per cob, number of grains per primary, panicle width, panicle length and 1000 grain weight had positive correlation with grain yield per plant through direct and indirect effects. KR 192-2, KR 219, KR 218, AKR 456, IS 28744 were found to be superior for all characters studied. Thus, selection of such R lines with superior characters contributing to yield will prove beneficial for development of hybrids in plant breeding programme.
