Genetic analysis for rind thickness, crushing strength and stalk breakage indicated that both additive and non-additive genetic variances were important in the determination of these characters. However, in case of crushing strength and stalk breakage additive genetic variance appeared to be playing a greater role, while for rind thickness non-additive genetic variance played greater role. Dominant genes were responsible for higher crushing strength and rind thickness and for lower stalk breakage. Average degree of dominance was in the range of overdominance for crushing strength and rind thickness and for stalk breakage it was in partial dominance range.
