黄河流域棉花品种区域试验中熟组35个品种(系)的丰产性及抗病性表现与分析

以黄河流域棉区中熟常规组和中熟杂交组棉花品种(系)为材料进行丰产性和抗病性比较试验。结果表明:常规棉CG11(华644)籽棉总产和皮棉总产均居第1位,产量分别达3 385.8 kg/hm2和1 381.35kg/hm2,增产极显著,霜前籽棉总产和霜前皮棉总产表现也较好;CG3、CG13产量表现也较高。杂交棉中以ZJ3(岱杂2号)籽棉总产量最高,达3 622.8 kg/hm2,比对照增产4.2%,表现较好的有ZJ3、ZJ13、ZJ14、ZJ18、ZJ2;皮棉总产量ZJ13最高,达1 448.7 kg/hm2,比对照增产8.5%,增产显著,较好的有ZJ14、ZJ3、ZJ2、ZJ4等。调查显示,所有参试品种均高抗枯萎病,抗或耐黄萎病。

Performance and Analysis of High-yielding Ability and Disease Resistance of 35 Cotton Varieties (Lines) in Middle-Mature Group of Huanghe Area Regional Test

The high-yielding ability and disease resistance of 35 varieties(lines) from middle-mature conventional and hybridized groups of Yellow River cotton area were analyzed in this paper.The results showed that the conventional cotton CG11(Hua 644) had the highest seed cotton yield and lint yield,which were 3 385.8 kg/hm2 and 1 381.35 kg/hm2 respectively and were very significantly higher than those of the check.The pre-frost lint yield and seed cotton yield of CG11 also performed better.CG3 and CG13 also showed higher yield.Among the hybrid cotton varieties,ZJ3 had the highest seed cotton yield as 3 622.8 kg/hm2,which increased by 4.2% compared to the check;ZJ3,ZJ13,ZJ14,ZJ18 and ZJ2 also had higher seed cotton yield;ZJ13 had the highest lint yield as 1 448.7 kg/hm2 and increased by 8.5% compared to the check;ZJ14,ZJ3,ZJ2 and ZJ4 also had higher lint yield.The investigation results showed that all of the experiment varieties(lines) had high resistance to blight,and resistance or tolerance to verticillium wilt.
