1983年由美国和澳大利亚引入美22、澳洲红两个红树莓新品种。美22是生长旺盛、抗病性强、大果型丰产品种;平均单果重4.00g,每666.7m~2产量可达1000kg。澳洲红易于根蘖繁殖,浆果品质特佳,也是抗病大果型丰产品种;平均单果重3.08g,每666.7m~2产量800～1000kg。两品种浆果均适于加工果汁饮料,出汁率可达85%。原汁稀释10～15倍果汁仍表现色泽艳红,风味可口。对两品种的生物学特性和栽培技术要点作了较为系统的观察研究。
In 1983 by the United States and Australia introduced the United States 22, Australia Red two new red raspberry varieties. The United States is a strong growth 22, disease resistance, large fruit-rich varieties; average fruit weight 4.00g, yield per 666.7m ~ 2 up to 1000kg. Australian red easy to reproduce the root tiller, berry quality is particularly good, but also the disease-resistant large fruit varieties; average fruit weight 3.08g, yield per 666.7m ~ 2 800 ~ 1000kg. Two varieties of berries are suitable for processing fruit juice drinks, juice rate of up to 85%. Juice diluted 10 to 15 times the juice is still showing red color, delicious flavor. The biological characteristics of two varieties and cultivation techniques made a more systematic observation.
