应用灰色关联度分析法综合评价马铃薯试验

Comprehensive Evaluation of Potato Experiment Using Grey Incidence Analysis

应用灰色关联度分析法,对2008年庄浪县应用全膜双垄集雨沟播栽培技术实施的马铃薯新品种(系)区试中参试的8个品种(系)的12个性状进行综合评价。结果表明:综合表现较好的品种是庄薯3号、陇薯7号、陇薯5号3个品种。其中庄薯3号的加权关联度最高,为0.878,主要表现为产量、单株产量、商品率高,生长势强,高抗晚疫病。陇薯7号,陇薯5号加权关联分别为0.766,0.761,主要是产量与综合性状表现较好。

Eight new cultivars(clones) grown in furrow and irrigated with rainwater harvested from double plastic cover ridge in a regional trial were comprehensively evaluated for 12 traits in Zhuanglang,Gansu province in 2008.The promising cultivars were Zhuangshu 3,Longshu 7 and Longshu 5.The weighted incidence degree was highest for the cultivar Zhuangshu 3,0.878.This cultivar was high in yield based on both hectare and hill and high in marketable potato percentage,vigorous,and resistant to late blight.The weighte...
