桉树种系对焦枯病抗性的初步测定

Measurement on the resistance of Eucalyptus cultivar to Cylindrocladium quinqueseptatum

为研究福建省有关桉树种系对焦枯病的抗性差异,选育抗病种系,2006年通过野外自然发病情况调查和室内人工接种测定,将收集的11个在福建主栽的桉树种系初步划分为抗病种系——巨尾桉9224、尾细桉M1;中抗种系——巨赤桉201-2、邓恩桉、柳桉、巨尾桉广9和尾巨桉Ug9;中感种系——本沁桉、尾巨桉3229;感病种系——巨桉3号、巨桉5号。

In order to study the resistant differences of Eucalyptus cultivars to Cylindrodadium quinqueseptatum between different cultivars, and choose the resistant cultivar, 11 selected cultivars were divided into 4 resistant types by investigation outdoor and inoculation indoor, they are resistant cultivars （Eucalyptus grandis × Eucalyptus urophylla 9224, E. grandis × E. camaldalensis M1 ）, moderate resistant cultivars （ E. grandis × E. camaldulensis 201-2, Eucalytus dunnii, E. saligna, E. grandis× E. urophylla guang 9, E. urophyUa × E. grandid Ug9 ）, moderate susceptible cultivars （ E. bethamii, E. urophylla × E. grandis 3229 ） , susceptible cultivars （ E. grandis 3, E. grandis 5 ）.
