应用灰色关联度分析法 ,对宁夏育成的 6个春小麦高产品系的主要农艺性状进行综合评价 ,结果表明 :730 -1品系最好 (r =0 75 89) ,730 - 2品系次之 (r=0 72 2 4 ) ,834- 3品系最差 (r=0 5 4 76 ) 。
In this paper,the main agricultural characteristics of 6 strains of the spring wheat (Triticum aestivum L.) bred in Ningxia were evaluated comprehensively and quantitatively by use of analysis method of grey related degree.The result showed that of the 730-1 strain was the best (r=0.7589), next to 730-2 (r=0.7224).that of 834-3 strain was the worst.The results of appeaise accorded with the expression of the strains in wheat breeding.
