摘　　要：通过对高品质棉杂交种科棉3号与江苏省主要推广杂交种中29和鲁棉研15在黄萎病严重发生条件下生育特性比较研究表明,该品种产量潜力大,早熟性强,在30000株/公顷群体下,成铃均匀分布,棉铃体积大,株高和叶片等营养生长平稳,蕾数多,结铃盛期成铃强度大,叶片光合作用强,光合产物运转效率高。说明该品种具有较强的抗黄萎病能力,在黄萎病严重田块能保持稳产高产。Under serious Verticillium wilt condition, the study was to investigate the difference of development characteristics between high quality hybrids cotton Kemian No. 3 and hybrids cotton Zhongmiansuo No. 29 , Lumianyan No. 15 which were popularize cotton in Jiangsu province. The results showed that this strong, under 30000 / hm^2 of colonies, boll setting distributed evenly steadily and have more buds, boll setting rate is high, the blades phot varietyoutput potentiality is large, early - maturing and the cotton boll volume is large. Nutritional organs grow osynthesize strongly and with high efficiency of photosynthetic attributions. It proved that this variety has stronger resisting verticiUium wilt ability, can keep giving stable high yields in serious field of verticillium wilt.
