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.
