樟子松引种驯化和遗传改良研究现状

樟子松为中国北方特有的珍贵树种,具有生长快、适应性、耐干旱瘠薄的优良特性,经济、社会和生态价值显著。因此,樟子松这一珍贵资源的引种驯化与遗传改良极为重要,在汲取国内外相关研究成果和学术观点的基础上,系统阐述了樟子松的种源试验、引种驯化、遗传改良、良种选育、种质保存及可持续利用等领域的研究现状和进展,指出了种质资源保存方面存在的不足,展望了种质资源可持续经营的广阔前景,提出了优异种质创新利用的具体思路和对策,以期为拯救并保护障子松资源提供理论参考。

Research Status on Introduction,Domestication and Genetic Improvement of Pinus sylvestris vat. mongolica

As one of the specific tree specie in Northern China,Pinus sylvestris var. mongolica has many unique characteristics such as fast growth, adaptability, resistance to drought and barren, and its economic, social and ecological value are obvious. Therefore, the domestication and genetic improvement of this precious resource is extremely important. Based on absorbing domestic and foreign research results, as well as academic point of view,the provenance test, domestication, breeding, genetic improvement,germplasm conservation and sustainable utilization of Pinus sylvestris vat. rnongolica were introduced in a systematic way,the shortcomings of the germplasm resources preservation and the prospects of sustainable management of germplasm resources were pointed out,the specific ideas and measures of excellent germplasm innovation and utilization were put forward,in order to provide reference to save and protect the resources of Pinus sylvestris var. mongolica.
