本文报道龙眼无感染鬼帚病毒苗木培育研究中的部分结果。从我省新选育的优质、丰产、外表健康的“立冬本”、“水南 1号”、“青壳宝园”、单株采穗、嫁接 ,通过热处理和定期观察与抗血清检测相结合方法 ,获得首批不带LWBV的母株 4 5株 ,扩繁 171株 ,在远离龙眼产地的纯稻区建立可用于培育龙眼无毒苗的采穗、取种母本园。经 8年观察 ,母树生长正常 ,无出现鬼帚病状 ;并开始挂果 ,保持原品种母树的优良性状。
This article reports some of the results of the longan non-infected ghost broom virus seedling cultivation study. From the new selection of our province of high quality, high yield, the appearance of healthy “Li winter”, “Shui Nan 1”, “green shell”, single ear harvest, grafting, heat treatment and regular observation and antisera detection phase The first batch of 45 non-LWBV mother strains was obtained and 171 strains were expanded. The non-LWBV-producing mother plants were cultivated in pure rice far away from the longan. After 8 years of observation, the growth of the mother tree is normal, there is no ghost broom symptoms; and began fruiting, maintaining the original character of the good traits of the mother tree.
