摘　　要：为了了解河北省育成转基因早熟常规棉的主要性状，为今后早熟棉品种改良提供指导，以河北省早熟组区域试验平均结果为依据，对2006~2014年河北省审定的13个转基因早熟常规棉品种（夏播棉除外）的主要性状进行了分析。结果表明：2006~2014年河北省审定转基因早熟常规棉的产量水平有所提高；生育期明显缩短，单株果枝数和株高变化不大；单株成铃数有所提高，铃重和衣分略有下降；纤维比强度有所提高，长度略有缩短，马克隆值有所降低；抗枯萎病性能较好，其中，有2个品种枯萎病抗性级别为高抗，其他品种均为抗；抗黄萎病性能较差，其中，有1个品种黄萎病抗性级别为抗，其他品种均为耐。因此，在今后的转基因早熟棉育种工作中，应注意抗黄萎病育种新材料和新品系的选择。In o rder to understand the main characters of transgenic early maturing cotton approved in Hebei Province, and provide guidance for the improvement of early matu ring cotton varieties in the fu-ture. Based on the average results of the early maturity group of Hebei Province,the the main characters of 13 transgenic early maturing cotton a pproved in Hebei Province in 2006-2014 were analyzed. The results showed that from 2006 to 2014,the production level was improved,growing period was significantly shorter, boll number per plant was increased,boll weight and lint percentage were slightly decreased,fiber strength has been improved and the length was slightly shorter and micronaire value was decreased. The resistant to blight was stronger,2 varieties showed high resistance and others were resistant. The resistant to V erticilli-um Wilt was weaker. Therefore,we should pay attention to breeding of resistance to Verticillium Wilt of new materials and new line selection in the breeding work of transgenic early maturing cotton in future.
