【摘要】 分析评价了“十五”以来湖北省审定的39个棉花品种的产量、抗病性、纤维品质等性状。结果表明：审定品种的产量水平明显提高；抗枯萎病品种仅占二成、黄萎病抗性没有突破；纤维长度、比强度和麦克隆值均有所改善；霜前花率、株高、单株成铃数、单铃重呈上升趋势,生育期呈下降趋势,衣分保持相对稳定；杂交棉单株成铃和单铃重优势明显,产量水平最高。更多还原

【Abstract】 The property of production,antiviral property and fiber quality of 39 cotton bred by Hu- bei province were studied since the Tenth Five-year Plan.The results showed that,the yield com- ponents of the audited varieties increase significantly.In addition,Fusarium wilt of cotton accounts 20% merely,and the study for Verticillium wilt has no manifest progress.According to the analy- sis,fiber length,fiber strength and micronaire-value are improved to some extent,the lint percent- age before frost,plant height,bolls per plant and single boll weigh arise tendencily,the growth pe- riod falls tendencily,and lint percentage is relatively stable.Finally,bolls per plant and single boll weight of hybrid cotton have obvious advantages compared to the conventional cotton,which lead to its highest production.更多还原
