The results showed that the gray correlation degree could more objectively and comprehensively evaluate the advantages and disadvantages of the tested Hemai varieties (lines), and the gray correlation degree ranking of each variety (lines) was basically consistent with the actual performance of varieties (lines), the grey correlation degree analysis can reflect the lines with excellent comprehensive characters. It provides a way for the breeding of new wheat varieties.展开更多
文摘为了评价出鹤麦系列小麦品系(种)综合性状的优劣和测定各个农艺性状对其产量的影响程度,本文对参加区域试验的11个鹤麦系列小麦品系(种)的11个性状应用灰色关联度进行了评价。结果表明:灰色关联度能较为客观、全面地评价参试鹤麦品种(系)的优劣,各品种(系)的灰色关联度排序与品种(系)的实际表现基本一致,灰色关联度分析可以反映出综合性状优良的品系,为小麦新品种的选育提供了一条途径。In this paper, in order to evaluate the advantages and disadvantages of the comprehensive characters of Hemai series wheat lines (varieties) and determine the influence degree of each agronomic character on its yield, 11 characters of 11 Hemai series wheat lines (varieties) participating in the regional test were evaluated by grey correlation degree. The results showed that the gray correlation degree could more objectively and comprehensively evaluate the advantages and disadvantages of the tested Hemai varieties (lines), and the gray correlation degree ranking of each variety (lines) was basically consistent with the actual performance of varieties (lines), the grey correlation degree analysis can reflect the lines with excellent comprehensive characters.
