马铃薯新品种模糊综合评判及模糊相似选择

采用模糊数学方法，对甘肃省马铃薯新品种和优良新品系进行综合评判。结果表明，８５—６—１４、陇薯２号、天薯６号达到优良评判标准。对新品系８５－６－１４、１７８－２６８进行模糊相似选择分析。结果表明，８５－６－１４与天薯６号最相似，１７８－２６８与陇薯２号最相似，因此可分别采用天薯６号和陇薯２号相应的农艺栽培措施管理８５—６—１４和１７８—２６８，此法可省去复杂的生产试验示范。

COMPREHENSIVE EVALUATION AND SIMILAR SELECTION BY FUZZY MATHEMATICS IN POTATO CULTIVARS

Abstract By the method of fuzzy mathematics, the comprehensive evaluation was made to the new potato cultivars and the fine clones from Gansu. The results showed that the cultivars (clones),85-6-14, Longshu No.2 and Tianshu No.6 were superior by evaluation cirtertion. The analyse was made to the new clones 85-6-14 and 178-268 by the similar selective method of fuzzy mathematics. The results indicated that 85-6-14 was similar to Tianshu No. 6 and 178-268 was similar to Longshu No.2. They can be planted by using the agronomic approaches with the similar cultivars.The similar selective method of fuzzy mathematics has important meaning to evaluation and rapid release of new cultivars. If it was used, the field experiment can be omitted.
