摘要： 本文提出利用自交作物单染色体纯合重组系检测数量性状基因座位（QTL）与遗传标记连锁关系的方差分析模型。增加重复可有效地减少样本容量、降底试验误差和提高检测QTL的灵敏度。应用方差分析将控制小麦每穗小穗数的两个QTL-Sn I和Sn II定位在7D染色体的着丝粒区域和长臂上。

Abstract: A statistical model of analysis of variance for detecting linkage between quantitative trait loci(QTL) and genetic marker(GM) in the single chromosome recombinants of selfing crop was developed. Increasing number of replications resulted in reducing sample size and increasing the sensitiveness of li
