皖江黄鸡品系杂交组合筛选试验

Screening of Cross Combinations of Wanjiang Yellow Chicken

以皖江黄鸡父系(HA系)、母本父系(HB1和HB2系)以及母本母系(HC1和HC2系)共5个品系为材料,开展父母代和商品代杂交组合试验,为配套系的建立提供依据。结果表明:父母代鸡繁殖性能较好的杂交组合是HB2(♂)×HC1(♀)和HB1(♂)×HC2(♀),HA(♂)×[(HB2(♂)×HC1(♀)]杂交组合的商品代鸡在早期生长速度、饲料转化比、成活率和屠宰率方面最具有优势,且商品代鸡三黄特征明显,胫长适中,符合市场需要。

The paternal line（HA line）,female paternal line（HB1 line and HB2 line）,and female maternal line（HC1 line and HC2 line） of Wanjiang yellow chicken were used materials.The cross combinations of parent generation and commercial generation were screened to provide evidence for the establishment of cross strain.The results showed that the reproductive performances of HB2（♂）×HC1（♀） and HB1（♂）×HC2（♀） were the best.The commercial generation of HA（♂）×[（HB2（♂）×HC1（♀）]grew fast at early stage,the feed conversion,survival rate and slaughter rate were better,and the commercial generation had clear three yellow characteristics,moderate shank length,which met the needs of market.
