| 摘 要： | 松材线虫病是危害松属树种的毁灭性病害,危害严重、防治困难。安徽省从2001年开始从疫区和非疫区的马尾松林分中选择324株抗病优树以及部分广东、广西种源,通过嫁接繁殖和人工接种松材线虫的方法进行无性系抗病性测定。2011年利用筛选出的68个家系的89个高抗无性系营建了1.6 hm2抗松材线虫病马尾松无性系种子园。各家系成活率90.9%～100%,平均成活率93.6%。

| Abstract: | Pine wood nematode(Bursaphelenchus xylophilus)disease is a destructive one for pines.It causes a serious damage and it is difficult to prevent.324 excellent disease resistance trees have been selected from Masson’s pine(Pinus massoniana) stand in epidemic area and non-epidemic area of Anhui province since 2001.With some provenances from Guangdong and Guangxi,the disease resistance of these clones had been tested by a way of grafting propagation and artificial inoculation of pine wood nematode.In 2011,89 clones with high resistance were chosen from 68 families.Then they were used to establish 1.6 hm2 clonal seed orchard.Survival rate of each family was 90.9%-100%,and the average survival rate was 93.6%. |
