春小麦主要产量构成因素间的灰色关联度分析

以巴彦淖尔市春小麦异地多点试验汇总数据资料。运用灰色系统理论分析方法，探索了春小麦主要产量构成因素间的关联度大小关系。结果表明，与产量关系最为密切的性状是千粒重，关联度为0．71999，其次是亩穗数，关联度为0．71685，再依次是穗粒数、穗长、穗粒重、株高、基本苗和生育期。在巴彦淖尔市以高产、优质为目标的春小麦新品种选育应选择大粒、多籽、多穗品种。

Grey Relational Grade Analysis of Main Factors Affecting Yield in Spring Wheat

The size testing that the main spring wheat output having assembled the data data, having wielded the gray system theoretical analysis method exploration composes factor room correlation degree with Ba Yan county nur city spring wheat strange land multiple spot concerns the main body of a book. That result indicates be most close properties, and output concerns is that the weight of a thousand seeds,correlation degree are 0.71999,secondly be that the mu of ear number,correlation degree are 0.71685,again in proper order be that the ear granule number, the ear are long,are high,fundamental seedling and childbearing period. The new breed of spring wheat taking high yield and high quality as target in bar City breeding responds to the breed choosing big granule,seediness, many ears.
