不同基因辅助选择方法对QTL的选择效率
Efficiencies of QTL Selection under Different Gene-assisted Selection Methods
摘要
Abstract
Assumed that the target trait was controlled by one QTL and polygenes, the effects of continuous selection on single trait in a closed population under genotype selection ( GTS) , gene-assisted best linear unbiased prediction ( GBLUP) and conventional animal model best linear unbiased prediction (BLUP) were estatimated by using computer simulation method, respectively. The efficiencies of QTL selection from GTS and GBLUP were analyzed by taking the method of conventional animal BLUP as the control. Compared with those from conventional animal BLUP, GTS and GBLUP would gain higher genetic response of QTL genotypic value, and faster increase of the frequency of QTL favorable allele, and the QTL selective efficiency of GTS was higher than that of GBLUP. The superiority of GTS and GBLUP compared with conventional animal BLUP for QTL selection was much obvious in short-term selection, but it would be decreased gradually and even disappeared with the increase of generation.关键词
