栽培无病毒苗木是防治苹果病毒病害的根本途径。1982—1989年,采用热处理、茎尖组织培养和热处理与茎尖培养相结合的3种脱毒方法,培育成21个品种的苹果无病毒母本树,连同交换、引[的共有41个品种的苹果无病毒母本树.保存于兴城苹果无病毒中心母本园中。1986年以来,分別向辽宁、山东、陕西等8省提供无病毒苹果原种苗1200多株,接穗1700多条。建立省级无病毒苹果母本园23处,繁育苹果无病毒苗木240万株,新建无病毒苹果园5.11万亩。无病毒树长势健壮,整齐一致,有明显的增产优势。为发展我国苹果无病毒化生产,提高产量,改善品质,解决病毒病防治问题,打下了良好基础。
Cultivation of virus-free seedlings is the fundamental way to prevent and cure apple virus disease. In 1982-1989, three kinds of virus-free female parent trees of 21 varieties were cultivated by heat-treatment, shoot tip tissue culture and heat-treatment combined with shoot tip culture. A total of 41 varieties Apple virus-free female tree. Preserved in Xingcheng Apple virus-free center in the mother garden. Since 1986, it has provided over 1200 virus-free apple seedlings and over 1,700 scions to eight provinces including Liaoning, Shandong and Shaanxi respectively. The establishment of the provincial virus-free apple mother garden 23, breed apple 2.4 million virus-free seedlings, the new virus-free apple orchards 5.11 million mu. Virus-free trees grow robust, neat and consistent, there is a clear yield advantage. For the development of China’s apple virus-free production, increase production, improve quality, solve the problem of virus disease prevention and control, laid a good foundation.
