小麦新品种主要农艺性状的灰色关联度分析

Grey Correlative Degree Analysis on the Main Agronomic Tratis of New Wheat Varieties

为更全面地了解新品种综合表现,采用灰色关联度分析河南省丰优小麦联合体两年11个新品种的主要性状。结果表明,两年关联度均较高的小麦新品种有濮麦1128、新麦51、漯麦163。2016年7个因素对产量的影响程度由高到低依次为千粒重、穗数、容重、穗粒数、基本苗、株高、全生育期,2017年依次为穗数、容重、穗粒数、株高、千粒重、基本苗、全生育期。

To better understand the comprehensive performance of new varieties,grey correlation analysis was used to analyze the main characteristics of 11 new varieties of Fengyou wheat combination in Henan Province. Results showed that wheat varieties with relatively high correlation degree were Pumai 1128,Xinmai 51 and Luomai 163. In the year 2006,the influencing degrees of factors affecting the wheat yield from high to low were in the order of 1 000-grain weight,ear number,volume weight,seeds per ear,basic seedlings,plant height and whole growth period. In the year 2007,the order was ear number,volume weight,seeds per ear,plant height, 1 000-grain weight,basic seedlings and whole growth period.
