Summary: This study utilizes advanced genotyping technologies to investigate the genetic structure of Torreya grandis, a species with high economic and ornamental values. A high-density linkage map is constructed, and the results suggest that the identified QTLs are relatively young and can be better utilized through clonal propagation.

Summary: This study constructed the first high-density genetic map for African bermudagrass and identified four genomic regions associated with turf establishment rate. These results provide important genetic resources for improving establishment rate in bermudagrass breeding through marker-assisted selection.

Summary: This study aimed to determine the importance of QTL monitoring and QTL inter loci interaction in safflower under normal and drought stress conditions. A new linkage map with 69 polymorphic AFLP markers was constructed, identifying 17 major QTL and 66 epistatic QTL for ten agronomic traits. These QTL accounted for 3.04%-24.71% and 8.31%-56.5% of the phenotypic variations of traits, respectively. Seven main genomic regions on linkage group (LG) 4 and LG5 were found to co-localize QTL for various traits, providing valuable information for future breeding programs to enhance drought tolerance.

Summary: The exchange of materials between sugarcane breeding programs in Brazil and Argentina will expand the genetic base of their germplasm banks. By analyzing the genetic diversity and population structure, breeders can select the most suitable parental accessions for efficient crossing. This knowledge will help improve breeding practices and increase the chances of obtaining more productive varieties.

Summary: This study investigated the genetic diversity and characteristics of F. oxysporum f. sp. fragariae strains isolated from strawberry cultivation sites in Korea. The results showed that there are distinct groups of strains present, and some strains have lower sensitivity to chemical fungicides. Continuous monitoring and management of F. oxysporum f. sp. fragariae, including the less chemically effective strains, is recommended.

Summary: This study assessed the genetic diversity and phylogenetic relationships of cowpea accessions in Togo using SSR molecular markers. The results showed rich genetic diversity and low population differentiation among the cowpea germplasm. This study provides an important foundation for the conservation and genetic improvement of cowpea germplasm in Togo.

Summary: Using AFLP markers, genetic variability of 37 plants of Fragaria nilgerrensis in six main mountain areas of Sichuan Province was investigated, showing a huge genetic variability and distinctive genetic groups among plants from the same mountain area. These results provide valuable reference data for surveying and protecting the germplasm resources of F. nilgerrensis in strawberry breeding programs.

Summary: Sporothrix, consisting of pathogenic species to humans and other mammals, has its epidemiology reshaped by molecular phylogeny. AFLP markers successfully distinguished Sporothrix species, with genetic cluster analysis revealing three distinct populations aligning with different species. Additionally, the study supports random mating strategy and shows skewed distributions of mating types in different species within the genus.

Summary: Hydrangea, an important ornamental crop cultivated for over 300 years, has been limited in genetic studies due to lack of genetic resources. However, a recent transcriptomic study and large-scale marker development have greatly expanded the genetic resources available for hydrangea, including high-density genetic linkage maps.

Summary: The population structure and genetic diversity of wheat varieties in the United States were examined using a panel of historical and modern varieties. The results showed that population structure was related to growth habit and kernel characteristics, which also corresponded with geographic distribution. Market class classification accounted for the greatest amount of variation. There was no evidence of decreased genetic diversity after the release of the first semidwarf wheat variety in 1961, and some varieties even showed increases in genetic diversity. The findings suggest that overall genetic diversity in wheat varieties has not declined in the long term, despite occasional fluctuations.
