摘　　要：研究结果表明,在山西运城常年治虫4～7次,天然异交成铃率高达61.6％以上。优良的晋A棉花不育材料单株成铃已达同类常规品种水平,表现了突出的早熟性和天然异交优势。The result indicated that the boll setting rate of the natural crossing could increased by 61.6% or even more under the condition of controlling 4 - 7 times a year in Yuncheng Shanxi and the boll setting rate of single plant for good cotton Jin - A materials could reach the same level as the conventional cotton varieties, which performed outstanding early maturity and advantage of natural crossing.
