摘要
综合评价44份国际马铃薯中心(CIP)马铃薯资源品系,筛选优良品系,为其在生产上的应用和推广提供参考。试验设在云南建水县,采用随机区组设计,3次重复,以‘合作88’为对照,采用DTOPSIS法对马铃薯品系的单株产量、干物质含量、淀粉含量、蛋白质含量、还原糖含量、大中薯率和晚疫病等级进行综合评价,以筛选出高产、优质的马铃薯品系。在44份品系中,有30份品系的综合表现优于对照品种,可作为进一步试验的备选品系,其余材料值小于对照,说明其综合性状差于对照,可作进一步试验观察或给予淘汰。‘滇薯23’Ci值排第2,产量排第2,产量是对照的3.4倍,淀粉含量中等,有较高的应用推广价值。
Forty-four International Potato Center(CIP) introduced new potato lines were comprehensively evaluated and promising lines were selected out in order to provide reference for their application and promotion in production.This trial was conducted in Jianshui County, Yunnan Province, in random complete block design with three replications,using variety 'Hezuo 88' as control. Yield per plant, dry matter content, starch content, protein content, reducing sugar content, large-and medium-sized tuber percentage and late blight resistance were evaluated using dynamic technique for order preference by similarity to ideal solution(DTOPSIS) so as to screen out high yield and high quality potato lines.Among the 44 lines tested, the comprehensive performance of 30 lines was better than that of control variety, which could be used as candidate lines for further trialing. Other lines' comprehensive performances were less than those of control, which could be used for further experimental observation or eliminated. Ci value of 'Dianshu 23' ranked second,yield also ranked second, 3.4 times the control variety, and the starch content was medium. This line has a higher application value.
