초록

Background: Ginger is a perennial herb belonging to the Zingiberaceae family, used worldwide as a spice and medicinal crop. Despite its widespread application, there are no domestically developed ginger varieties in Korea most are imported. This study aimed to lay the groundwork for future gin- ger breeding efforts by evaluating and comparing the agricultural characteristics and active compo- nents of native ginger varieties collected within the country and those imported from China. Methods and Results: Korean landrace (KL) and Chinese landrace (CL) resources were collected. KL had a greater number of stems but shorter lengths than CL. KL was characterized by densely packed slices forming a straight Type I configuration, whereas CL featured moderately packed slices in a curved Type II layout. Regarding the rhizome slices, KL comprised a higher number of smaller slices, in contrast to CL, which had fewer but significantly larger slices. The weight of KL rhizomes averaged 457.7 ± 67.8 g, surpassing that of the CL rhizomes, which weighed 394.1 ± 64.0 g, indicating a statistically meaningful difference. Further analysis of the concentration of the three gingerols (6-, 8-, and 10-gingerol) in fresh ginger revealed that KL contained a significantly higher gingerol concentration than CL. Conclusions: The findings of this study are of significant value as foundational data for establish- ing parameters for variety breeding and for assessing each genetic resource under uniform cultiva- tion conditions.
