In Ji’an, the question of what can grow is inseparable from the season after harvest. Many grapevines in cold regions need to be laid down and covered with soil for winter protection. Beibinghong is notable because the Chinese Academy of Agricultural Sciences’ Institute of Special Animal and Plant Sciences describes it as able to overwinter in Ji’an without that burial step. That statement belongs to one named cultivar; it should not be generalized to every grape planted in the Yalu River valley.
The institute’s 2014 account traces the cultivar to a breeding cross begun in 1995, using Zuo Youhong as the maternal parent and a Shan-Ou F2 line, 84-26-53, as the other parent. The selected F5 material passed Jilin provincial approval in January 2008. A cultivar is the result of repeated selection, not a wild vine that simply happened to appear in the vineyard. Its history links plant breeding to a practical regional problem: finding fruit that can withstand cold while serving a specific wine-making purpose.
