Result Based on directly regenerated plant of in vitro plant of Xinjiang cotton, the cotton epicotyl treated by pre-culture for 3-5 d was immersed in bacteria for 15 min and co-cultured for 2 d. Cephalothin at 100 mg/L was used to inhibit bacteria after 50 mg/L kan selection. And the combination of cytokinin with relatively high content and auxin with low content was used in its directly budding culture to obtain resistant seedlings.

结果］在新疆棉花离体培养植株直接再生植株基础上，经3~5d预培养处理过的棉花上胚轴，在浸菌15 min共培养2 d后，经50 mg/L kan筛选，用1000 mg/L头孢霉素抑菌，并用相对高含量细胞分裂素和低含量生长素的组合对其进行直接出芽培养，从而获得抗性小苗。
