| 摘 要： | 采用灰色关联度分析法对国家马铃薯中晚熟西北组天水试点2008年6个马铃薯品种(系)试验资料的产量、生育期、株高、商品薯率、干物质含量、淀粉含量、植株退化指数、环腐病薯率、植株晚疫病指数9个性状进行综合评价,结果表明,综合性状表现良好的品系是L 0031-17和天99-5-4,其加权关联度接近,分别为0.720和0.716,等权关联度分别为0.706和0.762。

| Abstract: | A total of nine characters including yield,growth period,plant height,marketable tuber rate,dry matter content,starch content,plant degeneration index,tuber ring rot rate,and potato late blight index in six potato varieties(lines),were evaluated by using grey correlative degree analysis in late-maturing potato northwest group ofthe Tianshuipilot site in 2008.The results showed that L0031-17 and Tian 99-5-4 both had a good performance ofcomprehensive traits.The weighted correlations ofthe two lines were close,0.720 and 0.716,while the equal-weighted correlations were 0.706 and 0.762,respectively. |
