| 摘 要： | 利用(亚洲棉×比克氏棉) 异源四倍体和陆地棉、海岛棉有色素腺体品种以及由(亚洲棉×比克氏棉)异源四倍体为母本, 以陆地棉和海岛棉有色素腺体品种为父本, 组配成的杂交后代群体, 对植株上十一个部位色素腺体密度在群体内的分布进行了初步分析。正态检验表明: 分离群体色素腺体密度的分布为平阔曲线。多项式回归分析结果表明: 色素腺体密度在杂种群体中变化范围较为广泛, 因而对杂种进行选择, 可望得到理想植株。多元回归曲线上各值的出现, 为在实践中研究色素腺体密度空间分布提供了科学依据。

| Abstract: | The space distribution of pigment gland density on eleven places was analyzed by allotetraploid of (%G.arboreum ×G.bickii%) and varieties with pigment gland of %G.hirsutum G.barbadense %and the progeny population which is crossed by allotetraploid of (%G.arboreum ×G.bickii%) × %G.hirsutum% and (%G.arboreum× G.bickii%) × %G.barbadense%. The normal test showed that the distribution of pigment gland was a flat curve in segregation population.The polynomial regression showed that the change range of pigment gland density was more wide in hybrid population ,our aim was to look for good plant by selecting hybrid. The value of curve provide scientific basis for studying the space distribution of pigment gland density in practice. |
