N应用灰色关联综合评价优质蛋白玉米研究初探

A Comprehensive Evaluation of Some New Qpm Varieties with the Relation Degree of Gray System Theory

应用灰色关联度分析法 ,对 6个优质蛋白玉米品种 (组合 ) ,从高产、熟期、抗病性、株型和果穗形态特征等 12个性状进行综合评估分析。综合评估结果表明 :旅 39莫Q×齐 2 0 5综合性状表现好 ,具有产量高、熟期适中、抗病性强等特点。此外 ,依据各品种的灰色关联度排序所进行的综合评估 ,能得到较完整的试验信息 ,对各参试品种做出更加科学的评价。

This thesis integrated evaluates 6 QPM hybrids strains with the relation degree of gray system theory.They were analyzed from 12 traits including high-yielding?growing period?disease resistance?plant form and green ear morphological characters.The comprehensive evaluation results showed that:Lu39MoQ×Qi205 ranked first,which gave high yield?good-growth stages and disease enduring.In addition,this method is expect to get the experiment information more integrated,systematic and evaluated the experimental result more scientific and rational.
