Abstract

Studies on forest tree breeding (FTB) in South Korea started in the 1950s and have achieved remarkable outcomes through various techniques and methods such as selective breeding, cross breeding, introduction breeding, and biotechnology. Despite these outstanding achievements, no attempt has been made to objectively and quantitatively evaluate the results of domestic FTB research. Here, we quantitatively analyzed past research trends using keywords of published journal papers and compared the current domestic research level of FTB with the international level. Using various keywords in this field, we searched for research articles published in the Journal of Korean Society of Forest Science, the Korean Journal of Breeding Science, and the journals listed on the Science Citation Index from 1962 to present. The analysis of these studies showed that the research on FTB has grown quantitatively in Korea, and has been conducted on various subjects. Research topics from Korea, in terms of purpose and species, are not significantly different from those of foreign countries. The genus Pinus has been the major subject of FTB studies both domestically and internationally. However, in foreign FTB research, the trees used for research have diversified each year, while they were not diverse in Korea. The FTB research capacity of Korean national institutions, such as the National Institute of Forest Science, continues to dramatically increase, while the research capacity of universities is relatively low. Based on the results of this analysis, it is necessary to establish a concrete and effective policy for future research and development of FTB.
