我们在1987年黑松×长白松30人工杂交试验林12年生时,从中复选了15株优树。它们速生、耐旱、耐寒和抗病、虫害。它们属于父母亲本性状融合型遗传类型。在2000年已对部份优树嫁接初繁,形成了无性系,为决选出1~2个优良无性系,为推广速生、抗逆的松树新无性系奠定了基础。
When we were 12-year-old in 1987 artificial crossover test plantation of Pinus sylvestris L. × Changbai pine, we selected 15 excellent trees. They are fast-growing, drought-tolerant, cold-tolerant and disease-resistant and pests. They belong to the parents of the trait fusion genetic type. In 2000, some excellent trees were grafted early, forming clones. In order to select 1 or 2 excellent clones, we laid the foundation for the promotion of fast-growing and stress-resistant new pine clones.
