摘　　要：搜集8个生产上应用的棉花品种与4个早熟品系,在麦棉套作模式下种植,通过调查棉花株高、果枝、三桃比例、单铃质量、衣分、霜前花率、棉花产量等性状指标,筛选出适宜麦棉套作的棉花品种。结果表明,随着棉花品种(系)生育期缩短,霜前花率与霜前皮棉产量呈增加的趋势,其中,HL1和LZ4这2个品系表现较好,霜前花率分别为74.5%和75.1%,霜前皮棉产量分别为1 153,1 203 kg·hm-2;而中棉所89与冀杂2号2个生育期较短的品种在8个品种中表现相对较好。In cotton-wheat system 8 cotton varieties and 4 lines were planted through investigating plant height, fruit branches, the ratio of three bolls, boll weight, lint percentage, the rate of pre-frost yield and lint yield to select cotton varieties suitable for cotton- wheat system. The results showed that the rate of pre-frost yield and pre-frost lint yield increased when the cotton growth period decreased. The rate of pre-frost yield of HL1 and LZ4 were 74.5% and 75.1%,and the pre-frost yield were 1 153, 1 203 kg·hm-2,respectively. As a whole, the CCRI 89 and Jiza 2 were better varieties among 8 varieties.
