Abstract:
Some research was done of nalural hybridization between Pinus thunbergii Parl. and P. massoniana Lamb . around Naming. The natural hybrid consisted of three types: one type takes more after P. thunbergii ;another takes more after P. massoniana ; the other is mid type which takes up the majority. Hybrid vigor was tested through comparison between the natural hybrid and its Parents in the following rspects: Morphology of branch and needles; anatomy of needle; traits of cone and seed; annual growth rhythm; growth of diameter ,height and volume; wood gravity. Karyotype and Bursaphelnchais xylophilus resistence. The utilization potential of the natural hybrid was also discussed.
