To study the selection efficiency for 5 traits selected in the swine breeding plan by LE,LD and DR marker in MAS and GAS in 5 discrete generations,respectively,3 closed nucleus base populations were designed: 100,200,300 sows,and 10 boars each population,where the pigs were unrelated.
结果表明,利用DR标记在各种情况下都比利用LD和LE标记获得的选择效率高;5个性状中,MAS对低遗传力、限性性状NBA的选择效率最高;当性状的QTL方差占遗传方差基本相同时,中等遗传力性状FCR的选择效率比高遗传力性状BF的更高;当性状的遗传力差异不大时,QTL方差占遗传方差比例大的性状FCR的选择效率比QTL方差占遗传方差比例小的性状ADG的更高。
