12月10日,安徽省林科院承担的抗松材线虫病马尾松种源及抗性育种技术项目通过国家林业局科技司组织的专家认定。项目组经过5年的攻关,筛选出高抗马尾松家系68个、高抗无性系89个。经测定,所选的抗性无性系株发病率比普通马尾松减少63.7%。江苏省林科院、南京林业大学、安徽全椒县瓦山林场等单位协作完成这项研究。目前,项目已在瓦山林场营建高抗马尾松无性系现地测定林18亩、抗性家系子代测定林16亩、高抗马尾松无性系采穗圃6亩、高抗
December 10, Anhui Academy of Forestry bear anti-pine nematode disease Pinus massoniana provenance breeding and breeding projects through the State Forestry Administration of Science and Technology Division experts identified. After 5 years of research, the project team screened out 68 families with high resistance to Pinus massoniana and 89 clones with high resistance to clones. It was determined that the resistant clones selected had a 63.7% reduction in incidence compared with normal masson pine. Jiangsu Academy of Forestry, Nanjing Forestry University, Quanjiao County, Anhui Wushan forest and other units to complete this study. At present, the project has been established in Wushan forest climatic test of high resistance Masson 18 acres of forest, resistance offspring measured offspring of 16 acres, high resistance Masson Pine clonal harvesting 6 acres of high resistance
