Starch Content and Starch Yield of Seven Introduced Potato Varieties under Different Ecological Environments of South Xinjiang

[Objective] The purpose was to analyze starch content and starch yield of introduced potato varieties under different ecological environments of South Xinjiang,to confirm the suitable potato varieties in special ecological areas,and to provide a scientific basis for introducing and cultivating the other areas potato of planter and process enterprises.[Method] Seven introduced potato varieties of South Xinjiang were planted in two different ecological environments,the Fourth and Ninth Regimen of the First Division of Xinjiang Production and Construction Corps,and determined and evaluated their starch content and starch yield.[Result] Feiwuruita has high starch content and good stability with starch yield,while Dingxuan2hao has the lowest starch content and worse stability relatively with starch yield.The varieties with high starch yield were Atlantic and Feiwruita.[Conclusion] The hereditary characters of potato varieties play a leading role in their starch content,while the ecological environments play an important role in forming of starch yield.
