Abstract:
      A field experiment was conducted in the semiarid loess hilly region of Dingxi to determine the difference on nutritional quality characters of nine potato varieties under side-seeding on ridge and full plastic-film mulching. In addition, the nutrition quality of each variety was evaluated by the method of subordinative function and factorial analysis of fuzzy mathematics to provide scientific basis for the selection of potato varieties in main producing areas of Gansu province. The results showed that the sequence of nine potato varieties on comprehensive quality ordered as Ganyin No.1> Ganyin No.2> Heimeiren>Xindaping> Qingshu No.9> Zhuangshu No.3> Longshu No.6=Dingshu No.1> Qingshu No.168, under side-seeding technique on ridging with full plastic-film mulching.
