１９７３～１９９６年用我国东北山葡萄抗寒种质资源与不抗寒的栽培品种进行种间杂交和重复杂交，其中１９７３～１９９２年定植５８个组合杂种苗，成活５３２４株。４种杂交模式抗寒力大小排列顺序是：（山葡萄×欧亚种）Ｆ１×山葡萄≥（山－欧）Ｆ１×（山－欧）Ｆ１≥（山葡萄×欧亚种）Ｆ１≥（山－欧）Ｆ１×欧亚种。果穗、果粒重量、果实含糖量４种杂交模式后代倾向山葡萄，即穗小、粒小、低糖遗传，但也分离出超高亲单株。已选育出在当地气候条件下，简易防寒可酿造干白（加糖发酵）品系７９－３３－３和８５－１４－４５，可露地越冬酿造干红葡萄酒品系８７－８－９６和新品种左红一；干白新品系７９－３２－３２。
From 1973 to 1996, we used interspecific hybridization and repeated crosses between cold hardy germplasm resources and non-cold resistant cultivars from Northeast China grapevine. Among them, 58 hybrids were planted in 1973-1992 and 5324 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 climate conditions, simple cold can be brewed dry white (sugar fermentation) lines 79-33-3 and 85-14-45, can be exposed to winter brewing dry red wine line 87-8-96 and new varieties left Red one; dry white new line 79-32-32.
