摘要:

分析了陆地棉超矮突变体的质量遗传规律, 结果显示, 该性状是受一对完全隐性基因控制的质量性状; 在国内外未见陆地棉中同类突变的报道, 暂将它的基因符号定为du。该突变体在自然条件下生长, 最终株高仅10.5 cm, 不能正常开花、结铃和吐絮; 但通过外源激素处理, 最终株高可以达57.8 cm, 并能正常结铃吐絮。

Abstract:

The inheritance of an ultra-dwarf plant mutant from upland cotton (Gossypium hirsutum L.) was studied, which showed that the mutant was controlled by single recessive quality gene. This gene was denominated as du tentatively. No similar mutant has been found in upland cotton. The mutation could not normally flower and produce bolls under natural conditions, and its mature height was only 10.5 cm. When treated with exogenous GA3, it could normally flower and boll, and plant height could reach 57.8 cm finally.
