摘　　要：[目的]培育适合新疆北疆棉区种植的早熟杂交棉品种,探讨杂种F1代的杂种优势,为北疆棉区提供高产优质早熟杂交棉品种。[方法]2011年以芽黄突变体为母本,配置14个杂交组合,并筛选出强优势组合。[结果]竞争优势分析结果表明:有11个参试组合子棉产量超过CK;有13个组合皮棉产量超过CK;其中组合KH1148和KH1150的早熟性好、丰产性突出且纤维品质综合性状优良。[结论]组合KH1148和KH1150可作为早熟杂交棉组合适于北疆棉区种植。株高、衣分、比强度存在正向杂种优势;以115-23和71-7为母本的组合,在农艺性状、产量等综合性状上有强的优势。[ Objective] The aim was to cultivate early maturing hybrid cotton varieties for planting in Northern Xinjiang, explore the heterosis of F1 hybrids, provide high yield and good quality early maturing hybrid cotton varieties. [Method]This paper took the virescent mutant as female parent, and 14 crosses, and screened the strong heterosis. [Result]The competitive advantage analysis results showed that there were 11 tested combinations yield more than CK, 13 combinations of lint yield more than CK, the combination of KH1148 and KH1150 in the early maturing, high yield and outstanding comprehensive characters of fiber quality. [ Conclusion] Combination of KH1148 and KH1150 can be used as the early maturing hybrid cotton combination was suitable for planting in Northern Xinjiang. Plant height, lint percentage, ratio of strength has positive heterosis. There had a strong advantage in the comprehensive agronomic traits, yield traits with 115 -23 and 71 -7 as the female parent.
