摘要
本文提出的增广 NCⅡ 设计,是指在 NCⅡ 设计含 f×m 个杂交组合的基础上、再添加 f+m 个纯系亲本的遗传交配设计。这一设计可对被研究性状的合适遗传模型(即加性,加性-显性,或加性-显性-上位性)作出统计选择;同时,还能对雌、雄亲的有关基因频率的同质性进行统计测验。文中推导了上述统计处理的遗传学依据,并以陆地棉的一个籽指性状为例解释了相应的统计程序。
The augmented NC Ⅱ design proposed in the article is a genetically mating design inwhich f×m crosses as well are f+m selfing progenies of homozygous parents are included.From the design,the statistical choice for genetic models(i.e.,additive,additive-dominance or additive-dominance-epistasis)of quantitative traits under considera-tion can be made.Meanwhile,the homogeneity of gene frequencies between female andmale parents can also be tested.The genetic basis for the above statistical treatment wasdemonstrated and the corresponding algorithm was illustrated by a real example of seed in-dex character of upland cotton(G.hirsutum).
