摘要Close to 50% of the annual production of the brown alga Saccharina japonica, about 2 million tons (fresh weight), is produced through farming in Shandong province, China, principally around Rongcheng. Under artificial selection for phenotypic traits (e.g. color, blade length) cultivated strains (cultivars) face the problems of inbreeding depression, which can be caused by the close relationships of the parental plants. Hence, in an attempt to evaluate genetic variations and relationships among cultivars, 15 major farmed cultivars were selected and sampled from seven major hatcheries and analyzed using 15 microsatellite markers. A total of 94 alleles were found across all samples, with allele numbers ranging from three to 17 per locus. All of the cultivars exhibited relatively high levels of genetic diversity, with mean Nei's genetic diversity (H) and the Shannon's information index (I) of 0.466 and 0.862, respectively. A UPGMA dendrogram grouped all cultivars into three main clusters. However, two of the most commonly farmed cultivars (DB and BN) from different hatcheries failed to cluster together. Instead, differently named cultivars from the same hatchery tended to group together, implying that their high similarities is partly due to the presence of genetic mixing among cultivars within a hatchery or misuse of cultivar's names. Genetic analysis performed by Bayesian model-based clustering revealed clear differentiation of three major subgroups (LJ-202 and LJ-205; LJ-C033; XS-2 and XS-BN) and one admixed group (the remaining ten cultivars). Our results revealed ambiguous genetic relationships among certain cultivars of S. japonica farmed in northern China. A more stringent and prudent regulation should be applied during breeding and production process in the future.
