From 1973 to 1996, interspecific hybridization and repeated crosses were carried out with cold hardy germplasm resources and cold-resistant cultivars from Northeast China grapevine. Among them, 518 hybrid seedlings were planted from 1973 to 1992, with 5,332 survived. The order of the cold hardiness of the four hybridization patterns is: (× × × × × × × × × × F1 × × × × F1 × (Mountain × European F1 × F1 × Eurasian species. The hybrids of ear, fruit weight and fruit sugar content progeny tended to be grapes, that is, spikelets, small grains and low sugar, but superpawn progeny plants were also isolated. Has been bred in the local climatic conditions, the winter can be exposed to brewing dry red wine strains 87- 8- 96 and the new variety Zuo Hongyi; dry white new line 79-32-32
