| 摘 要： | 本文以10个小麦品种和按双列杂交配制的45个组合为材料,研究了异常点对小麦遗传距离与杂种优势间最优关系的影响。结果表明:当样本容量较小时,异常点对遗传距离与杂种优势间最优关系影响较大,随着样本容量增加,其影响逐渐减弱,仅对最优关系的形式和拟合程度有所影响。

| Abstract: | The effects of outlier on the optimum relationship between genetic distance and heterosiswere studied in wheat. The materials were composed of 10 varieties and their 45 combinations bydialled mating design. The results showed that the effects of outlier were significant while thenumber of sample was small. When the number of sample increased, the influence of outlierdecreased, simply on the form of the relationship and correlation coefficient. |
