Abstract: This paper introduces the breeding of new potato cultivar “Kexin No.17”which is special for French Fries. In 1997 by hybridizing between F81109, a high yield and high commercial tuber ratio cultivar, and B5141-6, an American cultivar which is characterized by its high matter content, lower reducing sugar content and good quality for French fries. By many years of selection, Kexing No17 was bred with white skin and the same color flesh. Kexing No17 was examined and approved as extension cultivar by Heilongjiang Crop Cultivar Examination and Approval in 2005. KexingNo.17 is a good French fries and high yield cultivar with resistant to viruses , and its dry matter content is about 23.37%, Vc 20.43mg/100g fresh tuber, Reducing sugar 0.213%. At the same time, the issues of how we select the parents and treat the progeny population for potato quality breeding are also discussed in the paper.
