黄河流域棉花区试临清点中熟棉品种性状表现分析

Analysis on Characters of Medium Maturity Cotton Varieties in the Yellow River Linqing Test Area

以黄河流域棉区中熟常规组和中熟杂交组棉花品种(系)为材料进行生育期、农艺性状、丰产性和抗病性比较试验。结果表明:常规棉CG3籽棉总产和皮棉总产均居第1位,分别比对照增产4.39%和8.86%,增产显著,霜前籽棉总产和霜前皮棉总产表现也较好;CG1和CG8产量表现也较高。杂交棉中ZJ2表现最好,籽棉总产和皮棉总产均居第1位,表现较好的有ZJ3和ZJ5。调查显示,所有参试品种均高抗枯萎病,抗或耐黄萎病。

The comparative tests on growth period,agronomic traits,high-yielding ability and disease resistance were conducted taking the conventional and hybrid groups of medium maturity cotton in the Yellow River test area as materials. The results showed that the conventional cotton variety CG3 had the highest seed cotton and lint yields,which increased by 4. 39% and 8. 86% compared with CK respectively and the differences were significant. The pre-frost seed cotton and lint yields of CG3 also performed better. CG1 and CG8 showed higher yields. Among the hybrid cotton varieties,ZJ2 performed the best,and its seed cotton and lint yields were both the highest. ZJ3 and ZJ5 performed better. Disease-resistant investigation results showed that all of the testing varieties had high resistance to blight,and were resistant or tolerant to verticillium wilt.
