应用模糊数学方法对来自国际马铃薯中心11份资源材料和国内6个优良品种在内蒙古西部半干旱地区进行综合评判。结果表明:乌盟851、B_(71)—240.2、紫花白3个品种具有丰产、商品薯率高和抗旱性强的特点,其单株产量、商品薯率、株高、根系拉力及累积冠层覆盖度等5个性状的综合评判均表现突出,达到优良的评判标准,具有重要的推广价值。模糊综合评判方法,比较全面地反映了品种的特征特性和应用价值,克服了单以产量为依据评定品种的缺陷,对抗早马铃薯资源的综合评价及推广应用具有重要意义。
Applying the fuzzy mathematics method, 11 resource materials from IUPV and 6 domestic excellent varieties were evaluated comprehensively in the semi-arid area of western Inner Mongolia. The results showed that the three cultivars of Wumeng 851, B 71 (71.240.2) and purpurea were characterized by high yield, high commercial potato yield and strong drought resistance. The yield per plant, commodity potato yield, plant height, root tension and cumulative crown Layer coverage and other five traits of the comprehensive evaluation are outstanding, to achieve good evaluation criteria, has an important promotional value. The fuzzy comprehensive evaluation method reflects the characteristics and application value of varieties more completely, overcomes the defect of evaluating varieties based on yield, and is of great significance to the comprehensive evaluation and popularization and application of early potato resources.
