Abstract:
A full 3x3 diallel cross of Aseel Peela (AP), Kadaknath (KN) and CARI-Red (CR) were used for comparison of performance of pure and crossbred chickens for immune organ weight and to estimate the relative importance of different types of gene action involved in the inheritance of this trait. Two different models commonly used for diallel analysis of poultry data were employed in this investigation. The analyses of variance among genetic groups revealed significant difference between crossbred and purebred in male, female and combined sex. Model B did not yield any result in case of reciprocal effects for immune organ except in combined sex for spleen, bursa and thymus percentage.
