摘要
研究了显性无腺体基因在3种不同的遗传背景上对棉花农艺性状的影响。结果表明,显性无腺体基因对棉花的产量、纤维长度和种仁营养品质等主要性状均无明显影响,但皮锦产量有下降,纤维长度有伸长的趋势。对棉花其它农艺性状的影响,不同的背景上表现不尽一致,在泗棉2号背景上,铃重显著下降;在CAUCS-2-81背景上,铃重、衣分、衣指和纤维伸长率均显著增加;而在中棉所12号背景上,衣分和纤维伸长率显著下降。
The effects of dominant glandless gene on agronomic characters of upland cotttoon(Gussypium) hiRsulum m L. )were investigated on three varietal backgrounds.There were no obvious influences on lint yield, fiber length and kernel nutritive quality after transferring.But the effect on other traits varied in different backgrounds. In the back ground of Simian 2,the boll weight of dominant glandless isoline was smaller than that of the recurrent parent.In the background of CAU`CS-2-8I,the boll weight,lint percentage,lint index and fiber elongation significantly exceeded those of the recurrent parent.In the background of Zhongmiansuo 12,lint percentage and fiber elongation were appar ently smaller than those of recurrent parent.
