基于DTOPSIS法对广西马铃薯品种(系)的综合评价

Comprehensive evaluation of Solanum tuberosum varieties(lines)in Guangxi province by DTOPSIS method

以22份马铃薯品种(系)为试验材料,应用逼近理想解的排序方法(DTOPSIS法)对马铃薯的株高、主茎数、芽眼深浅、667 m2产量、花色苷含量、淀粉含量、干物质含量、还原糖含量等8个性状指标进行综合评价。其中,赋予产量性状指标中667 m2产量的权重值最大,为0.3000。结果表明,22个供试品种中,‘DNJ大红心’‘DNJ小红心’‘桂农薯1号’综合性状最好,可作为良种在广西地区进一步示范推广。

Twenty-two varieties(lines)were used as test materials,the dynamic technique for order preference by similarity to ideal solution(DTOPSIS)method was applied to comprehensively evaluate eight trait indicators of Solanum tuberosum.The eight character indexes respectively were plant height,main stem number,eye depth,the average yield per 666.7 m2,anthocyanin content,starch content,dry matter content and reducing sugar content.Among them,the weight value of the yield per 666.7 m2 was assigned the largest weighted value,which was 0.3000.The result showed that potato varieties(lines)‘DNJ Dahongxin’‘,DNJ Xiaohongxin’an‘d GuinongshuNo.1’were observed the best comprehensive characters among the 22 tested varieties,which could be further demonstrated and promoted in Guangxi province.
