 ABSTRACT

Genetic variability, heritability, genetic advance and genetic advance over mean   were carried out for charcoal rot component traits, fodder quality traits, yield and their component traits in 236 minicore accessions of sorghum (Sorghum bicolor (L) Moench) during rabi season of 2016-17 at the Main Agricultural Research Station, Dharwad. High PCV and GCV were observed for grain yield per plant (g), plant height (cm), panicle length (cm), number of primaries per panicle, disease parameters, brix percentage, stem thickness (cm), chlorophyll content at flag leaf and maturity stage and fodder yield per plot (kg).  All the traits showed a narrow difference between PCV and GCV, indicating that observed variability has been primarily due to genotypic differences with the least influence of environment. High heritability coupled with genetic advance over mean was observed for plant height, disease component traits, panicle length, number of primaries per panicle, panicle weight, 100-seed weight, panicle width, brix percentage, stem girth, chlorophyll content at flag leaf and maturity stage, fodder yield per plot and grain yield per plant, there by indicating that selection would be effective in improvement of these characters as they are controlled by additive genes.

Key words: Sorghum, fodder, charcoal rot, heritability, genetic advance
