摘要
[Objective] The objective of this paper was to screen out suitable high- yielding cultivars and to understand the current yield performance of wheat in Anhui Province. In addition, the influencing factors on wheat yield were discussed to es- tablish suitable cultural practice. [Method] Main popularized cultivars and some new strains of wheat were selected as matedals and planted in the Funan Farm and Longkang Farm in 2009-2011. The yield stability and influencing factors on yield of wheat were discussed. [Resalt] In Anhui Province, the weather had a great influence on wheat yield, resulting in significant differences in wheat yield among different years. Drought was the main factor restricting the yield. [Conclusion] （1） It was easy to achieve high yield when the three influencing factors on wheat yield were coordi- nated. （2） The occurred drought disaster in 20tl was the main factor limiting the 1 000- grain weight and final yield of wheat. （3） Different cultivars showed different yield stabilities. Among the test wheat cultivars, two cultivars （Wanke 06290 and Yannong 19） showed good yield stability, while Xinfumai No.1 showed higher yield. （4） The three influencing factors played different roles in different cultivars. In the promotion process, the characteristics of wheat cultivars should be fully understood. To achieve high yield, integrating cultural practices is a necessity.
[目的]筛选适合安徽省种植的高产小麦品种，了解安徽省目前小麦产量表现，对产量的影响因素进行探讨，以便制定适宜的小麦栽培方法。[方法]2009～2011年选取安徽省主推小麦和最新选育的小麦新品系在阜南、龙亢两点种植。研究3年来小麦品种丰产稳产性及产量三要素对小麦产量的影响。分析制约安徽省小麦产量的主要因素。[结果]气象因素对小麦产量的影响较大，不同年份间小麦产量差异明显．干旱是制约小麦高产的主要因子。[结论]①产量三要素协调易获得小麦高产。（2）2011年度的干旱是制约小麦千粒重的主要因素．进而影响小麦的产量。③不同品种的丰产稳产性不同，该试验中皖科06290和烟农19表现出较好的稳产性，新福麦1号表现出较好的丰产性。④对不同特性的小麦品种，产量三要素对不同品种的产量重要性不同。在小麦推广过程中充分了解品种特性，根据小麦品种特点配套栽培措施，使小麦达到高产。
