本试验采用不完全双列杂交法,对不同来源的9个肉鸡品系按父、母系分成两组,进行了20个杂交组合的配合力分析,结果表明:5个父系间56日龄体重一般配合力差异极显著,以A_1品系最高;4个母系间差异不显著;各杂交组合间特殊配合力差异极显著。该性状的广义和狭义遗传力都较高,分别为0.96和0.69。各父系、母系及20个杂交组合间56日龄存活率和饲料转化比差异不显著。
In this study, incomplete diallel cross method was used to analyze the combining ability of nine broiler breeds from different origins by parental and maternal lines. The analysis of the combining ability of twenty hybrids showed that: The results showed that there was a significant difference in force between the three maternal lines with the highest A 1 line, but no significant difference among the four maternal lines. The trait was broadly and narrowly heritability 0.96 and 0.69 respectively. There was no significant difference in the survival rate and feed conversion ratio at 56-day-old between maternal, maternal and 20 hybrid combinations.
