摘要
我国北方地区,特别是东北地区,冬季气候严寒,葡萄均需下架埋土防寒。已有山葡萄虽很抗寒,但结果系数低,果穗、果粒均小,产量极低,扦插又不易生根。为此,从1974年开展了野生山葡萄的选种工作,以期获得丰产优质、扦插易于成活、抗寒性强的酿酒新品种。 一、选育经过 ‘左山二’是1974年在黑龙江省尚志县苇河镇志成村的野生山葡萄(Vitis amurensisRupr.)资源中,选得的‘74003’单株繁殖而成的无性系。当年11月采集成熟的一年生蔓,1975年繁殖自根苗并定植于优良品系比较鉴定圃。扦插较易生根。自1978年开始,同时进行果实性状、农业生物学特性观察和酿酒试验,至1980年结束观察。1979年定植自根苗100株,结果后进一步观察确认其农业性状和酿酒品质均优。1984年在所内扩繁8.6亩,同年在黑龙江省友谊农场、吉林省通化市园艺研究所等单位进行区域适应性鉴定。1989年3月由吉林省农作物品种审定委员会审定为新品种,定名为‘左山二’。
'Zuo Shan Er' (code name : 74003) is a clone variety selected from a wild grape of Vitis amurensis Rupr. which was discovered at Zhi Cheng Village, Weihe Town, Shang Zhi County, Hei Long Jiang Province in 1974.
This variety has such characters as female flowers, compact berries, round and black. Average cluster weight is 109.3g. The contents of solude solids, organic acids and tanins in the fruit juice are 15.95% , 166%, and 0.0666% respectively. Bud break rate is 87.7%. Fruit shoot percentage among all new shoots reaches 86.6%. There are 2 clusters on a new shoot averagely.
For a 5 year old vineyard, the fruit yield might be as high as 1356.6 kg per Mu under suitable cultivated conditions.
The wine made from 'Zuo ShanEr' fruits, being of high quality, got 91.6-95.2 points from four sensory evaluations held in 1980,1984, 1988, and 1989, respectively.
This variety can withstand as low temperature as-39.2℃ and there is no cold damage during winter without covering. The growth period from bud break to fruit ripening is 120-125 days. 'Zuo Shan Er' is suitable to be cultivated especialy at the high latitude where has cold winter and short frostfree period.
'Zuo Shan Er' was named by the Committee of Crop Examine and Approve Jilin Province in March 1989.
