| 摘 要： | 对8个小麦新品种(系)的产量和其7个主要性状进行灰色关联度分析,以明确新麦系列新品种(系)产量和产量构成因素及其它性状之间的关系,为优势新品系的评价提供依据。结果表明:影响产量的7个因素,2012年的排序为穗粒数千粒重单位面积穗数、成穗率株高春季最大分蘖数基本苗数,2013年的排序为成穗率单位面积穗数千粒重株高穗粒数基本苗数春季最大分蘖数;两年关联度均靠前的小麦新品种(系)有新科麦169、新麦212。

| Abstract: | Grey relational degree analysis was conducted to study the relationship between 7 main char-acters and yield of 8 wheat varieties .The results showed the order of 7 characters influencing yield was kernel number per spike＆gt;thousand-kernel weight＆gt;spike number per 666.7m2 and percentage of ear -bearing till-er＆gt;plant height＆gt;maximal tillering in spring＆gt;basic seedling number in 2012 , and percentage of ear -bear-ing tiller＆gt;spike number per 666.7m2 ＆gt;thousand -kernel weight ＆gt;plant height ＆gt;kernel weight per spike ＆gt;basic seedling number ＆gt;maximal tillering in spring in 2013 .Xinkemai 169 and Xinmai 212 ranked the front in the sequence of relational degree in the two years . |
