摘要	Dalian is the most important farming region in China for the economically important kelp Undaria pinnatifida and there are several major hatcheries for seedling production of this alga in this region. The excess zoospores are discharged from the hatchery to the sea after the seeding process is completed. They are expected to have the potential to colonize the rocky reefs nearby and form a population in the wild. We discovered a subtidal wild population (W22) near the outlet of discharged seawater of a nearby hatchery in Dalian in 2022. Its origin was unclear. The sporophytes of W22 are characterized with some desirable economic traits and thus have the potential to be exploited for breeding purpose. Identification of its origin will be helpful for its better exploitation in the breeding program. In the present study we used informative mitochondrial sequences and nuclear microsatellites to analyze the genetic relationship of W22 with the farmed populations produced in the nearby hatchery and other wild populations from Dalian. The results showed that W22 was genetically close to other subtidal wild populations and some wild populations on the cultivation rafts, but highly differentiated from the farmed populations. We thereby confirm that W22 has not been founded recently by the zoospores discharged from the nearby hatchery and suggest that it has been derived from the introduced stocks from Korea in 1930s. The very limited pedigree of farmed populations detected in W22 suggests that it has not been impacted by the zoospores discharged from the hatchery. This study represents a case of successfully determining the origin of a newly discovered wild seaweed population through genetic analyses based on informative DNA markers.
