摘要
采用灰色系统理论中关联度分析法 ,对 1995～ 1996年新疆自治区大麦新品种区域试验中的 6个供试品系进行了多性状的综合评价。结果表明 :大 94 3品系综合性状最好 (r1=0 7785) ,POLAND次之 (r2 =0 76 71) ,HARRINGTON综合性状最差 (r6 =0 6 90 1)。综合评判结果与品种(系 )在生产实际中的表现基本一致。认为灰色系统理论中灰色关联度分析法对作物新品种的选育。
By using the way of grey correlation degree 6 new varieties of barley region test were wholly appraised in 1995 1996 in Xingjiang.The results showed that the comprehensive characters of Da 943 stain was the best.next to POLAND.The comprehensive characters of HARRINGTON was the worst. The results of whole appraise accorded with the expression of the varietis in agricultural produltion.
