棉花新品种冀1316主要性状稳定性分析

以棉花新品种冀1316为试材,2009~2010年在河北省棉花不同生态亚区（中熟亚区、中早熟亚区、早熟亚区）的6个试点进行了2 a多点试验,研究品种主要性状的稳定性。结果表明：冀1316抗病性强,产量高,稳产性好,纤维品质优良,枯萎病指数2.9,黄萎病指数15.6,平均皮棉产量1 778.9 kg/hm2,纤维长度31.0 mm,比强度30.3 cN/tex,马克隆值4.6,整齐度84.6%,伸长率6.4%;并且果枝数、株铃数、单铃重、衣分等主要产量性状,纤维长度、比强度、马克隆值等纤维品质性状,以及枯萎病指数和黄萎病指数均比较稳定。该品种适于在河北省各植棉亚区大面积推广。

Stability Analysis of Main Characters of New Cotton Variety Ji1316

The stability of main characters of new cotton variety Ji1316 was studied through the experiments in six sites in the ecological sub-regions of cotton in Hebei Province from 2009 to 2010.The results showed that it had strong disease resistance,high and stable yield,and good fiber quality.Fusarium wilt index was 2.9,and Verticillium wilt index was 15.6.The average lint yield was 1 778.9 kg/hm2,the fiber length was 31.0 mm,the fiber strength was 30.3 cN/tex,the micronaire was 4.6,the uniformity was 84.6%,and the elongation was 6.4%.The yield components such as the numbers of fruit branches,bolls per plant,boll weight,lint percentage,and the fiber quality such as the fiber length,strength and micronaire,and the diseases resistance were stable.It was suitable for all the cotton-growing areas in Hebei Province.
