《江西农业科技》1981年第十期上发表了叶顺万同志题为《试论杂种优势固定的可能性》一文。(下面简称为《试论》)该文以显性假说为依据,认为杂种优势是由对生长有利的许多显性基因控制,杂交后,在F_1里集中了两个亲本的全部显性基因,从而出现了超亲优势。即具有AAbbCCdd基因型与具有aaBBccDD基因型的两个亲本杂交后,F_1出现AaBbCcDd基因型。根据基因分离和独立分配原则,通过基因重组,在F_2及以后各代中有可能获得少量的集中了全部显性基因的纯合体。即具有AABBCCDD基因型的个体类型。由此,该文得出结论,在杂交水稻的后代中,通过多代选择,得到一些种性稳定,产量接近杂交水稻的新品种(系),就是杂
In the tenth issue of “Jiangxi Agricultural Science and Technology” in 1981, Comrade Yeh Shun-Wan published a paper titled “The Possibility of Fixing Heterosis.” (Hereinafter referred to as “trial”) Based on the dominant hypothesis, the article considers that heterosis is controlled by many dominant genes that are good for growth. After hybridization, all the dominant genes of both parents are concentrated in F_1, Thus appeared super-pro-edge. That is, the AaBbCcDd genotype was found in F_1 after the AAbbCCdd genotype was crossed with two parents with the aaBBccDD genotype. According to the principles of gene isolation and independent distribution, it is possible to obtain a small number of homozygotes with all the dominant genes concentrated in F_2 and later generations through genetic recombination. Ie the individual type with the AABBCCDD genotype. Thus, the paper concluded that in the offspring of hybrid rice, some new varieties (lines) with stable species and close yield to hybrid rice were obtained through multiple generations of selection
