试验于1987～1989年在乌兹别克共和国实验生物研究所和塔什干农学院进行。研究结果表明,用矮秆、早熟陆地棉和海岛棉杂交,F_1的营养生长优势弱,而生殖优势强。集约化类型陆地棉和海岛棉杂交种的叶面积小,叶绿体数量少,而单叶绿体的光合作用强度和光化学活性增强,杂交种可以很经济地利用细胞资源。试验结果还显示,陆地棉、海岛棉栽培种与野生、半野生亚种的杂交后代表现出明显的核质基因互作效应。当野生、半野生棉为母本时,后代的主茎高度,果枝长度,叶面积和根系发育受到抑制。
The experiment was conducted in 1987-1989 at the Institute of Experimental Biology, Uzbekistan and Tashkent Agricultural College. The results showed that F 1 had a weak vegetative growth and strong reproductive superiority in hybrids with dwarf, precocious G. hirsutum and G. barbadense. Intensive types of Gossypium hirsutum and G. barbadense hybrids have a small leaf area and fewer chloroplasts, while the photosynthetic intensity and photochemical activity of single chloroplasts are enhanced. Hybrids can utilize cell resources economically. The results also showed that the hybrid progeny of G. hirsutum and G. gossypii cultivated with wild and semi-wild subspecies showed significant nuclear-gene interaction. When the wild, semi-wild cotton as the female parent, offspring of the main stem height, fruit branch length, leaf area and root development was inhibited.
