Three methods of estimating the numbers of genes segregating for quantitative characters using doubled haploid lines are presented. The first uses estimates of the range and genetical variance of an F1 or F2 derived population. The second adapts the genotype assay method of Jinks and Towey (1976) to F2 derived lines. The third uses the variances of an F2 derived population. Statistical problems of obtaining meaningful estimates using these methods are discussed and it is concluded that genotype assay is the best method for distinguishing between few and many genes. These methods are illustrated using data from an experiment containing doubled haploid lines of barley developed using the H. bulbosum system.
本文提出了三种利用双单倍体系估算分离数量性状基因数的方法。第一种方法利用 F1 或 F2 衍生群体的范围和遗传方差的估计值。第二种方法将 Jinks 和 Towey（1976）的基因型测定方法应用于 F2 衍生系。第三种方法利用 F2 衍生群体的方差。本文讨论了使用这些方法获得有意义估计值的统计问题，并得出结论，基因型测定是区分少数基因和多数基因的最佳方法。本文使用来自一个包含利用 H. bulbosum 系统开发的大麦双单倍体系的实验数据来说明这些方法。
