对在双列杂交分析的应用中所争论的问题进行评论。从统计的观点,文献涉及到模型的选择,固定的或随机的基因型作用。从遗传的角度,评价了用两种假设去解释双列杂交结果的尝试。第一个假设关于在亲本中基因的独立分布这一点,对提出适当的解释是最关键的而在真正实践中似乎是无法接受的。第二个假设认为没有上位性的论点可能常常是不正确的。上位性影响一般配合力和特殊配合力均方、方差的估计,且是以不能预见的方式产生的。至于对遗传解释的选择,由双列杂交分析提供的统计描述可被用来帮助解答这些问题,即特殊配合力的重要性及用一般配合力或亲本表现来预测杂种后代的表现。
Comment on the issues raised in the application of diachronic analysis. From a statistical point of view, the literature deals with the choice of model, either fixed or random genotypes. From an genetic perspective, attempts to explain the results of a two-line hybridization using two hypotheses were evaluated. The first hypothesis regarding the independent distribution of genes in the parents is the most crucial for proper propositions to be put in place and appears to be unacceptable in real practice. The second hypothesis that there is no epistolary argument may often be incorrect. Epistasis affects both general combining ability and special combining ability mean square, variance estimation, and is produced in an unforeseeable way. As for the choice of genetic interpretation, the statistical descriptions provided by the two-line hybridization analysis can be used to help answer these questions, the importance of special combining ability and the prediction of the performance of the hybrid offspring using the general combining ability or parental performance.
