摘　　要：为培育适合新疆北疆棉区种植的早熟杂交棉品种,2008年配置7个杂交组合,2009年对该批组合进行比较试验研究,以筛选出强优势组合,为北疆棉区提供高产优质早熟杂交棉品种。结果表明:参试7个组合产量均超过CK产量;其中组合K7显著高于K2,极显著高于K4、K1、K6、K3,组合K5显著高于K4、K1,极显著高于K6、K3;组合K5和K7的早熟性好、丰产性突出且纤维品质综合性状优良。组合K5和K7可作为早熟杂交棉组合适于北疆棉区种植。In order to cultivate early-maturity cotton variety,seven hybrid combination were made and compared with experimental study in 2009.The screened strong advantage combination could provide high-yield,high-quality,early-maturity hybrid cotton varieties.The results showed that all combinations yield were higher than CK yield.The K7 yield was significantly higher than that of K2,and was significant higher than that of K4,K1,K6 and K3 extremely.The K5 yield was significantly higher than that of K4 and K1,and was significant higher than that of K6 and K3 extremely.The K5 and K7 were high-yield,high-quality,precocious cotton variety and their comprehensive characteristics were excellent.K5 and K7 were suitable for cultivation in northern Xinjiang.
