中国葡萄主产区冬季埋土防寒,生长季喷施化学农药,加大了生产成本与生产风险(李文超和王振平,2012)。选用适合中国气候条件的高抗逆的酿造品种是中国葡萄酒产业目前急需解决的问题之一(刘玺华等,2013;张振文等,2013)。‘北馨’是山葡萄与欧亚种杂交后代。2004年选为优良单株,2007年开始在北京海淀、朝阳、大兴、延庆及天津静海等地进行区域试验,结果表明其抗寒性强,在北京、天津等地冬季不埋土防寒可以安全越冬,生长季病害较少,结实性强,稳产性优于‘北玫’,酿酒品质优良。2013年12月通过北京市林木品种审定委员会的审定,定名为‘北馨’。
In winter, the major grapes in China are buried in cold weather and chemical pesticides are sprayed during the growing season, increasing production costs and production risks (Li Wenchao and Wang Zhenping, 2012). The selection of highly resistant varieties suitable for the climatic conditions in China is one of the most pressing issues for the Chinese wine industry (Liu Xihua et al., 2013; Zhang Zhenwen et al., 2013). ’North Xin’ is a mountain grape and Eurasian hybrids offspring. 2004 was selected as excellent single plant, 2007 began in Beijing Haidian, Chaoyang, Daxing, Yanqing and Tianjin Jinghai regional trials, the results show that its cold hardiness, in Beijing, Tianjin and other places can not be buried in winter cold can be safe from cold Winter, less growing season disease, strong, stable yield better than the ’North Rose’, wine quality. In December 2013, it was approved by Beijing Municipal Forest Variety Certification Committee and named as ’North Xin’.
