This study was conducted using data from single crosses (partial diallel) of male lines, group I (LL, TL, ZL, TT, LT, ZT, ZZ, LZ, TL), female lines, group II (PP, KP, VP, KK, PK, VK, VV, PV, KV), besides two control lines (LLc and PPc). A completely randomized block design, with three replicales, 82 single crosses treatments with nine females for experimental unit was used in the analyses. The production traits analyzed, eleven total, were: fertility at 32nd, 38th, 42nd […]

This study was carried out to study the combining ability of parental broiler lines using factor analysis of production traits. The single crosses (partial diallel) among the male lines of group 1 (LL, TL, ZL, TT, LT, ZT, ZZ, LZ, and TL) and female lines of group 2 (PP, KP, VP, KK, PK, VK, VV, PV, and KV). A completely randomized blocks design, with three blocks, 81 single crosses and nine females per cross was used. The production traits, were […]
