摘要
太原花猪群体继代选育一世代的选择,采用了综合评定法。照顾家系血统关系是必要的,但降低了主选性状背膘厚的选择效果。从二世代起,采用综合选择指数(I_2)进行选择是适宜的。
The first generation of Spotted Taiyuan Pig population was selected using the method of comprehensive assessment. Although it is necessary to consider clan blood heritage, the effect of the main selecting trait thickness of the back-fat is reduced. Therefore, from the second genera- tion on, it is suitable to use the index of comprehensive selection.
