Abstract
A seven-parent half-diallel cross was analyzed for white center, white belly and alkali digestibility value(ADV). The analysis of variences were significant for all characters at 1% level. Both general and specific combining ability were significant for all characters. Non-additive genetic varience predominated for ADV(12hr. treatment) and additive effects were more important than non-additive effects for other characters. With the exception of ADV(12hr. treatment), which showed complete dominance, partial dominance in a negative direction was observed for the other characters. Heritability values were high in all characters. White belly was high positively correlated with white center and ADV.
