New strains have been bred and selected, with better characteristics, e.g. higher seawater temperature resistances and higher yields.

Shan Chi Saccharina (Laminaria) is one of the most important economic seaweeds. Previously, four genetic linkage maps of Saccharina have been constructed and five QTLs have been identified. In this work, Saccharina longissima () and Saccharina japonica (), which showed obvious differences in morphology and g. This study aimed to evaluate the genetic relationship between R11 and Batian with their parents HDT, RS, SL8 and confirm the occurrence of T and R genes using DNA markers. Genome-wide single nucleotide polymorphism (SNP) markers were obtained through Diversity Arrays Technology sequencing (DArTseq). The genetic relationship was analyzed by Principal Component Analysis and hierarchical clustering. ![]() Hierarchical clustering revealed less than 10 dissimilarity index apart from HDT that recorded above 20. Eleven genotypes carry both T and R genes, therefore, with broad-based resistance to CBD. The study confirmed the narrow genetic relations within the Coffea arabica coffee varieties and further confirmed the occurrence of multiple gene resistance in R11 and Batian that will not break easily to new pathogen races. View. The first genetic map was reported in 2007 and the first QTL analysis in 2010 (83,88). Mapcreate Software Series Of ProgressivelySubsequent studies have reported a series of progressively higher density genetic maps and more extensive QTL identification (90,136,137, 141). Traditionally, only a limited number of organisms have been studied in detail, but modern genomic tools are enabling researchers to extend beyond the set of classical model organisms to include novel species from less-studied phylogenetic groups. This review focuses on model species for an important group of multicellular organisms, the brown algae. The development of genetic and genomic tools for the filamentous brown alga Ectocarpus has led to it emerging as a general model system for this group, but additional models, such as Fucus or Dictyota dichotoma, remain of interest for specific biological questions. In addition, Saccharina japonica has emerged as a model system to directly address applied questions related to algal aquaculture. We discuss the past, present, and future of brown algal model organisms in relation to the opportunities and challenges in brown algal research. View. There were many traditional quantitative studies on the blade length, width and thickness, the stipe length, and the iodine content (Fang, 1983;Wu and Lin, 1987). It is intensively cultivated on large scales in a number of Asian countries. The current annual, global production is about 8 million tons valued as about 4 million US dollars. To further advance the cultivation of this species, detailed research of genetics and breeding studies are required. Recently, with the advancement of sequencing techniques, the genomics and comparative transcriptomics data were yielded, and quantitative trait locus (QTL) mapping has been conducted, along with genetic linkage maps constructed to this species. New strains have been bred and selected, with better characteristics, e.g.
