不同品质类型冬小麦产量的环境变异研究

本研究选用3种不同品质类型的4个冬小麦品种，研究其产量在新疆乌鲁木齐、昌吉和木垒3个试验点的环境变异。结果表明，不同品质类型的冬小麦品种产量差异较大，中筋小麦的产量高于其他类型；同一品质类型小麦的产量在不同地区间存在差异，其中木垒点小麦产量高于乌鲁木齐点，乌鲁木齐点高于昌吉点；不同品质类型的小麦在不同试验区产量差异显著，中筋冬小麦与其他品质类型相比，其产量受生态环境的影响相对较小；冬小麦的千粒重和穗粒数在不同生态环境条件下呈现出较大的变异，不同品质类型间存在差异。

Effect of environment on yield of winter wheat of different quality types

The field trail was conducted in Urumqi, Changji and Mori of Xinjiang to study environmental variation of yield of three different types of quality with four winter wheat cultivars. The result showed that yield of wheat cultivars of different quality types differed greatly and yield of wheat cultivar of middle quality was more than that of other wheat cultivars of quality types; yield of wheat of same quality types differed greatly in various sites and yield of wheat in Mori was more than that in Urumqi, yield of wheat in Urumqi was higher than that in Changji; yield of wheat of different quality types significantly varied in various sites and yield of winter wheat of middle quality associated with environmental effects were smaller than that of other wheat cultivars of quality type; variability of 1 000 kernel-weight and grains of spike of winter wheat in different sites were larger and that of different quality types varied.
