Abstract

The potential of seaweed aquaculture is restricted by high labor, production and processing costs, leading to low economic viability. Selective breeding can improve yields and cultivation efficiency, thereby decreasing production costs. Until now, genetic resources as input for Saccharina latissima breeding trials have been sourced strictly locally, due to concerns regarding outplanting genetically exogenous material in local waters. Here we study, for the first time, worldwide interregional fertility of the seaweed S. latissima, in order to assess the potential of including global S. latissima genetic resources for selective breeding with regard to heterosis. We quantified the yield (as an indicative aquacultural performance) and morphological traits of intra- and interregional S. latissima hybrids originating from a broad range of locations in a common garden experiment. Our results show that the practical application of worldwide S. latissima genetic resources in breeding programs is feasible based on global interfertility. We found a wide morphological diversity of hybrids and observed significant heterosis in interregional hybrids. The degree of heterosis could not be linked to geographic distance. These findings reveal that worldwide genetic resources can considerably contribute to S. latissima breeding programs and could offer a major next step in improving yields and quality traits.

糖海带种群的全球杂交和杂种优势：糖海带育种的下一步。

海藻养殖的潜力受到高劳动力、生产和加工成本的限制，导致其经济可行性较低。选择性育种可以提高产量和栽培效率，从而降低生产成本。到目前为止，由于考虑到在当地水域外植遗传外源物质，作为甘蔗育种试验投入物的遗传资源严格来自当地。本研究首次研究了海苔的全球区域间育性，以评估将全球海苔遗传资源纳入杂种优势选择育种的潜力。在一个普通的园林试验中，我们量化了来自广泛地点的区域内和区域间的latisima杂交种的产量（作为指示性水产养殖性能）和形态特征。本研究结果表明，基于全球互育理论，将世界各地的柽柳遗传资源实际应用于柽柳育种是可行的。杂交品种形态多样，区域间杂种优势显著。杂种优势程度与地理距离无关。这些发现表明，世界范围内的遗传资源可以极大地促进美洲藜的育种计划，并可以为提高产量和质量性状提供重要的下一步。补充资料：在线版本提供补充资料，网址为10.1007/s10811-025-03447-7。

期刊介绍： The Journal of Applied Phycology publishes work on the rapidly expanding subject of the commercial use of algae. The journal accepts submissions on fundamental research, development of techniques and practical applications in such areas as algal and cyanobacterial biotechnology and genetic engineering, tissues culture, culture collections, commercially useful micro-algae and their products, mariculture, algalization and soil fertility, pollution and fouling, monitoring, toxicity tests, toxic compounds, antibiotics and other biologically active compounds. Each issue of the Journal of Applied Phycology also includes a short section for brief notes and general information on new products, patents and company news.
