Korea Forest Service "Research on Increasing and Distributing Larch 'Clone Seedlings'... Stabilizing Seed Supply"

A study is underway to mass-produce and distribute larch with excellent traits through tissue culture. The purpose of this research is to ensure a stable supply of larch seeds.


On the 24th, the National Institute of Forest Science announced that it will begin a field adaptability test study to compare and analyze the growth characteristics of clone seedlings (tissue-cultured seedlings) produced by tissue culture, and to utilize the results for developing management technologies.


Clone seedlings refer to plants or groups that are genetically identical, propagated asexually from a parent plant (stock plant).

Larch has excellent wood quality, is straight-grained, and grows quickly, making it relatively advantageous for supplying timber according to demand. For the same reasons, the area of larch plantations has been increasing recently. However, the seed supply sector is currently unstable and unable to meet demand.


The Forest Science Institute developed a tissue culture technology for producing clone seedlings by inducing somatic embryos to reduce the instability of larch seed supply and to establish propagation technology for superior individuals.


Somatic embryo induction is a technology that replicates artificial embryos similar in morphology and function to zygotic embryos. Based on the developed clone seedling propagation technology, the Forest Science Institute has produced and distributed somatic embryos and established 12 plantation sites nationwide.


The field adaptability test study will be conducted to compare and analyze the growth characteristics and site adaptability of seedlings produced from seeds with those of clone seedlings planted in plantations selected by considering the planting year and climate zones in northern, central, and southern regions, among plantations established with clone seedlings produced from 2017 to 2023.


The research results obtained in this process will be used for future clone seedling distribution and plantation planning.


Researcher An Chan-hoon of the Forest Tree Resources Research Division said, “The Forest Science Institute continues to develop technology to mass-produce and distribute larch with excellent traits,” adding, “Through this, we will strive to produce high-quality larch clone seedlings and increase their practical use in the field.”
