摘要
对中南及华东地区二头乌猪及小耳猪(金华猪Ⅱ系除外)的10个品种(系)群体近4万个数量性状数据进行多元遗传分析。结果表明,小耳猪系统内的两个猪种不仅具有紧密的遗传关系,而且有着相似的体型和生产性能。在二头乌猪系统中,华中两头乌猪各群体也有着相似的体型和生产性能,但金华猪却在繁殖性能和胴体品质上表现特殊,独聚一类。 与生化遗传标记的研究结果结合,作者认为可将我国中南及华东地区的二头乌猪及小耳猪系统11个品种(系)归并为3个同种异名地方猪种,建议将华中两头乌猪统一划分为“江西系”、“湖广系”及“湖北系”3个选种目标各有侧重又相互协调的品系,在中南地区的适当省份建立“二头乌猪种猪中心”。
The multigenetic analysis on nearly 40000 firsthand data of body measurements, carcass merit and production performance of the 10 pig breeds related before ( not contain the II strains of Jinhua pig breed ) in central southern and eastern China has been carried out. The results enunciate that the populations in the short-ear pig system have not only a very close genetic relationship, but also similar body type,carcass merit and production performance. But in the black head-hind pig system, the Jinhua breed gets into another position in the fertility performance and carcass merit, although the Huazhong black head-hind pig populations have the same performance of production and body type.
Intergrating this results with the former genetic relationship research, the authors think that it is reasonable to reclassify the whole 11 pig populations of the black head-hind pig system and the short-ear pig system into 3 synonym native pig breeds. A suggestion of classifying the 6 Huazhong black head-hind pig populations into ' Jiangxi' , 'Hubei' and 'Huguang' three strains, in which each has its own focal and also coodinated seed selection goals, and a suggestion of establishing 'China Black Head-hind Pig Centre' in a proper area in Central Southern China has been proposed.
