| Abstract | The species of genus Larix widely distribute in subarctic and arctic zone. The number of species is estimated as ten or more, only one of which distributes in Japan. This species, Japanese Larch (in Japanese, Karamatsu), is endemic in Japan, and its distribution area is mainly central mountainous regions (fig. 1). The northern and eastern limit is Mt. Zao in Miyagi Prefecture, the western limit is Mt. Hakusan, and the southern limit is Mt. Tengu and Mt. Yamazumi of Akashi Mountain Range. The eight provenances, known to be representative, are named as follows: KawakamiHigashiyamanashi, Yatsugatake, Asama, Fuji, Minami-Alps (The South Japan Alps), Nikko, KitaAlps (The North Japan Alps), and Kiso. The species grows very well not only in central Japan but also in eastern and northern Japan, where it does not naturally distribute. Therefore, it has been an important forestry species of the boreal zone in Japan. The Forest Tree Breeding Center (FTBC) has engaged in selection and progeny testing of plus trees, selection and determination of trees that have few spiral grains, artificial crossing, and selection of recommended varieties and development of new varieties. Japanese Larch has also been widely evaluated internationally, and an international provenance test has been implemented by use of seeds collected in 1956 from 25 natural forests. The participating countries number more than ten, and include Japan, the USA, New Zealand, and several European countries. The information above emphasizes the importance of widely conserving natural genetic resources that are the base and source of forestry varieties and breeding material. |
