Taking high yield，good resistance to disease and high starch content as breeding targets，this study selected гибрид82 introduced from Russia as female parent and a Russian variety Журавинка as male parent；and developed‘ Kenshu No.2’ with high yield，good resistance to disease and high starch content by system selection method.‘Kenshu No.2’ is of mid-late maturity and starch processing type. Its dry matter content is 25.71%-29.51%，starch content is 19.71%- 23.51%，VC content is 49.3 mg · kg^-1 and reducing sugar content is 0.07%. Its average yield is 34 338 kg·hm^-2. It has high yield and high starch content. Its field resistance to late blight is stronger than that of the contrast‘ Kexin No.12’. It is highly resistant to PVX and resistant to PVY. It is
suitable for planting in Heilongjiang Province.
