| 摘 要： | 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。

COMPREHENSIVE EVALUATION POTATO GERMPLASM FOR DROUGHT RESISTANCE BY THE METHOD OF FUZZY MATHEMATICS |
| |
| Abstract: | By the fuzzy mathematical method, the comprehensive evaluation was made to 17 potato varieties from CIP and home in the scmiarid region of Inner Mongolia. The results showed that the varieties, Wumeng 851, B71—240. 2 and Zihuabai, had specialities of high yield, high market tuber rate and stronger drought resistance and were significantly superior to other varieties in the characters of tuber yield per plant, market tuber rate, plant height, root pulling resistance and accumulated canopy cover. Their performance were superior by evaluation criterion. The comprehensive evaluating method of fuzzy mathematics can reflect comprehensive characters and the applied value of potato varieties. The method can overcome the shortcoming of evaluation by yield factor and may have important significance for comprehensive evaluation and popularization of potato germplasm for drought resistance. |
