用灰色关联度综合评价中国北方片春播花生新品种

Comprehensive evaluation to new spring-sown peanut varietiesin northern China with gray relational grade analysis method

通过灰色关联度分析 ,对 1998、1999年两年度参加中国北方片区域试验的 9个春播花生早熟新品种 (包括对照品种 )的优劣进行了综合评价。结果表明 ,郑 86 0 36 - 2 6 - 1的加权关联度最高 ,为 0 .72 87,综合性状优良 ;95- 3位居第二 ,加权关联度为0 .72 2 3;位居第三的是邢 8715,加权关联度为 0 .6 730。

Nine new early-maturing peanut varieties tested in the regional experimentation of north China from 1998-1999 were evaluated with the gray relational analysis method. The results showed that zheng86036-26-1 had the best synthetical properties, with the highest weighted relational grade (0.7287); the others were 95-3 and xing8715, their weighted relational grades were 0.7223 and 0.6730 respectively. The evaluation results were essentially identical with the field performance of the varieties tested.
