摘要
根据近50a、先后5批日本落叶松(Larixleptolepis(Sieb.et.Zucc)Gord)的引种试验及以日本落叶松为亲本的杂交试验结果,讨论了引进日本落叶松遗传资源的方法和策略。研究结果表明:引种必须经过驯化过程才能实现;以日本落叶松为亲本的杂交后代是在适应能力、生长量、干形、材性、纸浆产量及种子产量各方面都得到改良的良种,并在抗寒、抗病方面普遍存在优势。
Based on the introductory trial of 5 times of Japanese larch for 50
years or so and the crossing trial with them, the methods and strategies of introducing
Japanese larch gene resources are discussed. Research results indicated that introduce must
be passed by domestication; hybrid progeny with parents of Japanese larch could be improved
on the adaptation, growth rate, form, wood property, pulp yield and seed yield and had common
dominance in cold-resistant and disease-resistant.
