2019年黄河流域棉区中熟常规区域试验参试棉花品系性状分析

Analysis of Cotton Lines Traits in Middle Medium Conventional Regional Test in Cotton Region of the Yellow River Basin in 2019

为满足棉花生产需求,以中棉所100为对照(CK),对2019年黄河流域棉区中熟常规组国家区域试验B组(运城点) 11个参试棉花品系的农艺性状、产量、品质性状及抗病性等进行调查分析。结果表明:QHB07皮棉产量(1 987.5 kg/hm^(2))最高,较CK增产24.65%,丰产性突出,株高偏高(108.9 cm),株型较紧凑,果枝较短、较平展,茸毛较少,茎秆较粗,铃卵圆形,单铃重高(6.4 g),衣分高,结铃性好,子指11.8 g,高抗枯萎病、抗黄萎病,极适合在黄河流域种植。

In order to meet the demand of cotton production,the agronomic traits,yield,quality traits and disease resistance of 11 cotton lines in group B(Yuncheng point) of the national regional test of medium maturity conventional group in the cotton region of the Yellow River Basin in 2019 were investigated and analyzed with the Zhongmiansuo 100 as the control(CK). The results showed that QHB07 had the highest lint yield(1 987.5 kg/hm^(2)),increased by 24.65% compared with CK,had prominent high yield,high plant height(108.9 cm),compact plant type,short and flat fruit branches,less hairy,thick stems,oval bolls,high single boll weight(6.4 g),high lint percentage,good boll setting,11.8 sub fingers,and high resistance to Fusarium wilt and Verticillium wilt,and it was very suitable for planting in the Yellow River Basin.
