[目的]筛选适合淮北地区种植的具有超高产潜力的小麦品种.[方法]于2006～2007和2007～2008年2个年度田间试验中分别对26个小麦供试品种的产量性状、分蘖特性、养分吸收特性及部分生理生化特性进行测定与分析.[结果]26个小麦供试品种中,烟农19、皖麦52和周麦18是适合淮北地区种植的具有超高产(9 000 kg/hm~2)潜力的小麦品种.对各品种的生理特性分析发现,超高产小麦品种的茎蘖数为1 300万～1 500万/hm~2;在各生育阶段干物质积累量较其他品种多;返青前,叶片叶绿素含量与其他品种无显著差异,但返青后则高于其他品种;超高产小麦品种形成100 kg籽粒所消耗的N和P_2O_5量较其他品种多,而消耗的K_2O量较其他品种少.[结论]该研究为淮北地区超高产小麦品种的选育及生产提供了理论依据.

[Objective] The study aimed to screen the super-high-yielding wheat varieties suitable for planting in Huaibei area.[Method] The characters of yield, tillering, nutrient uptake and some physiological and biochemical characters of 26 wheat tested varieties were determined and analyzed through the field tests resp. in 2006-2007 and 2007-2008.[Result] Among 26 wheat tested varieties, Yannong 19, Wanmai 52 and Zhoumai 18 were the super-high-yielding wheat varieties with the yield level up to 9 000 kg/hm~2 that were suitable for planting in Huanbei area. Analysis on the physiological characters of 26 varieties found that, the super-high-yielding wheat varieties had the stem tillering number of 1 300×10~4-1 500×10~4/hm~2 and their dry mater accumulation amount were more than other varieties; before the returning green stage, the chlorophyll content in the wheat leaf had little difference between the super-high-yielding wheat varieties and other verities, but the former was larger than the later after the returning green stage; the consumption of N and P_2O_5 which could produce 100 kg wheat grains for the super-high-yielding wheat varieties was more than other varieties, but their consumption of K_2O was less than other varieties.[Conclusion] The study provided the theoretical basis for the breeding and production of the super-high-yielding wheat varieties in Huaibei area.
