以转基因抗虫棉R93- 4等五个品系为材料 ,对其生育特性及有关经济性状进行了研究。结果表明 ,R93- 4 ,R93- 6 ,RH - 4 ,R93- 5,R93- 3等品系与对照相比生育进程提前 ,早熟 ,结铃集中 ,着铃性好 ,但铃重、衣分较低。转Bt基因抗虫棉多表现苗期长势弱 ,铃小等缺点。
Five lines of transgenic Bt cotton R93-4 were used as materials to study their reproductive characteristics and economic traits. The results showed that the developmental process of R93 - 4, R93 - 6, RH - 4, R93 - 5 and R93 - 3 were earlier, more precocious, low. Transgenic Bt transgenic cotton seedling performance more weak seedling, bell and other shortcomings.
