日本开展的“抗松材线虫育种”研究获得成功。该课题组首先从受害最重的松林中选拔幸存个体,嫁接在火炬松砧木上。两年内人工接种松材线虫两次,从中选定超强抗性的赤松92株、黑松16株,确定为抗性无性系。经过这 Japan’s “anti-pine wood nematode breeding” study was successful. The research team first selected the surviving individuals from the most affected pine forests and grafted them on the loblolly pine rootstocks. Two years of artificial inoculation of pine nematode twice, from which the selection of super-resistant Adenosine 92, black pine 16, identified as resistant clones. After this
