| 摘 要： | 依据《中国棉花品种志(1978-2007)》及品种审定公告，建立了1978-2007年间长江流域、黄河流域和西北内陆三大棉区审定推广的839份陆地棉品种的生育期、株高、第一果枝节位、铃重、衣分、皮棉产量、纤维长度、比强度、马克隆值等14个主要农艺经济性状的数据库。通过统计分析，结果表明纤维长度、衣分、生育期、马克隆值、铃重在不同棉区不同品种间差异小，稳定性好，枯、黄萎病抗性、叶色和种植密度在各棉区品种间变化差异均很大。西北内陆棉区的枯、黄萎病抗性最好，长江流域棉区的枯、黄萎病抗性最差，种植密度表现为西北内陆棉区>黄河流域棉区>长江流域棉区，比强度表现为西北内陆棉区>长江流域棉区>黄河流域棉区，且相同棉区不同品种间变化差异较大；皮棉产量表现为西北内陆棉区>长江流域棉区>黄河流域棉区。综合以上结果说明西北内陆棉区特别是新疆棉区有利于发展优质棉，长江流域棉区应加强抗病品种的培育。

| Abstract: | The study of database constructed based on the Flora of Cotton Varieties in China （1978-2007） and official variety registration announcement. This database collected 839 cotton varieties （Gossypium birsutum） with 14 agronomic trait such as growth period, plant height, sympodial branch nod, boll weight, lint percentage, lint yield and fiber quality, which authorized and promoted in Yangtze River, Yellow River and Northwestern inland cotton production zone. The statistical analysis demonstrated that the difference of fiber length, lint percentage, growth period, micronaire and boll weight was not significant among varieties in three major cotton production zones; but the difference of fusarium wilt resistance, verticillium wilt resistance, leaf color and planting density was significant. Varieties with highest fusarium wilt resistance and verticillium wilt resistance of varieties were from Northwestern production zone, and the lowest were from Yangtze River production zone. The planting density was highest in Northwestern zone, followed by Yellow River zone and Yangtze River zone; the fiber strength was highest in Northwestern zone, followed by Yangtze River zone and Yellow River zone, and the different varieties presented significant difference in the same production zone. The fiber yield showed the same law as fiber strength. This study suggested that varieties with good fiber quality were more suitabledeveloped in northwestern cotton production zone, especially in Xinjiang Province, and more disease resistant varieties should be developed in Yangtze River cotton production zone. |
