数量性状位点的相对选择效率Relative Selection Efficiency for Quantitative Trait Loci
王辉,陈瑶生
摘要(Abstract)：
从理论上采用蒙特卡罗(Monte Carlo)模拟的方法研究了不同遗传力条件下数量性状位点的直接选择(DSQ)和以表型为基础的选择(TBS)在10个不重叠世代中的选择反应以及DSQ相对于TBS的优势。结果表明,在10个世代中DSQ的选择进展在几乎总是大于TBS的选择进展,说明DSQ较TBS具有优越性;但DSQ的相对选择效率(RSE)会随着世代数的增加而呈现较迅速下降的趋势,单个性状情况下RSE则呈直线下降的趋势。随着选择代数的增加,DSQ将失去其优越性,TBS在遗传进展上将超过DSQ。
