摘要： 运用限制因子学说和灰色关联分析方法，探讨小麦品种多个主要农艺性状因子与产量的关系，确定影响产量的主要的性状限制因子。结果表明，在诸多性状因子中，最高茎数、 穗数、穗粒数等性状因子，是冬小麦产量的主要性状限制因子，其它性状因子为非限制因子。进一步提出在冬小麦的栽培中，应以群体为基础，在达到一个合理的群体、保证穗数的前提下，主攻个体，采取相应的措施，增加穗粒数，为提高冬小麦产量打下基础。

Abstract: The relation between a few main characters and the yield in the 7 winter-wheat cultivars was studied by means of the restrictive factors and the relational grade analysis of grey system theory. The results showed that the yield is more closely related with population, ear quantity and grains per ear, which are main character restrictive factors. The others are not character restrictive factors. Therefore, the colony is the most important. The winter-wheat colony is get reasonable at first in the growing, afterwards, ear quantity and grain per ear is assured by means of effective measures, which is the basis of winter-wheat high-yield.
