Genetic variability studies in sorghum (Sorghum bicolor (L.) Moench)

Abstract

The current study was carried out using twenty-two sorghum genotypes including five checks at Experimental farm, Genetics & Plant breeding department, College of Agriculture, VNMKV, Parbhani. The study was done during Rabi 2024-2025 using randomized block design (RBD) with two replications. A group of twenty-two genotypes were employed to assess genetic variability for yield as well as its contributing traits. A significant degree of variability was noted in yield components. Plant height (cm), brix reading and grain yield per plot (kg) had the highest GCV and PCV. While, moderate GCV and PCV was observed for stem girth (cm), number of leaves, leaf: stem ratio, fodder yield per plot (kg) and lowest GCV and PCV observed for days to 50% flowering. High heritability combined with high genetic advancement for plant height, number of leaves, leaf: stem ratio, stem girth, fodder yield per plot, brix reading and grain yield per plot. Hence, this insight indicates that these traits can be effectively employed in sorghum enhancement programs through selection method.
