Abstract:

Genetic variability, heritability, genetic advance and correlation were estimated for charcoal rot component traits, yield and its component traits. High values of PCV and GCV were observed for majority of traits, indicating a greater scope for improvement of these traits. High heritability coupled with high genetic advance over mean was observed for majority of traits, indicating these characters would be more effective for further improvement through simple selection. Significant and negative association of lodging per cent with grain and fodder yield indicated lodging affects grain yield and fodder yield. The association between stay green and charcoal rot parameters was negative indicating stay green types are tolerant to charcoal rot. Brix percentage recorded significant negative correlation with charcoal rot parameters. Stem girth exhibited significant positive association with number of leaves per plant, spreading of fungus and fodder yield per plot. Based on these results it could be concluded that, to enhance fodder yield and quality, the breeder need to focus on medium thick stem, more number of leaves, higher chlorophyll content at flag leaf and at maturity and high brix percentage. These traits would reduce the charcoal rot disease there by enhancing quality and quantity of the fodder and grain.
