从1986年至今,我所苹果无病毒苗课题先后参加“七·五”、“八·五”国家重点科技攻关项目和省科委重大科技攻关项目,主要进行苹果脱病毒及无病毒苗繁殖技术的研究。截至1994年,共获无病毒苹果品种18个、矮化砧木7个。在全国12个省(市)建立实验示范园36处,种苗繁殖点11个,形成相当大的科研推广协作网。各地苹果无病毒树的栽培反应均表现出明显优势。现将各地的苹果无病毒树与有病毒树在生长结果上的不同反应总结如下:
From 1986 to now, the subject of my apple virus-free seedling has successively participated in the national key science and technology research projects of “7.5”, “August 5” and major science and technology projects of the provincial Science and Technology Commission, Study on Virus Seedling Reproduction Technology. As of 1994, a total of 18 virus-free apple varieties and 7 dwarfing rootstocks were obtained. In the 12 provinces (cities) to establish experimental demonstration garden 36, seed breeding sites 11, forming a considerable research and promotion network. Cultivation responses of apple-virus-free trees all showed obvious advantages. Now around the apple virus-free tree and virus tree growth results in the different responses are summarized as follows:
