Summary: This study investigated the genetic diversity and population structure of four Triticum and Aegilops species using different gene markers. The results showed that the CBDP marker had higher efficiency than the SCoT and SSR markers. There was a higher distribution of genetic variation within species than among them, with Ae. cylindrica and Ae. tauschii having the highest values. The cluster analysis indicated that the SSR marker was more effective in grouping of tested accessions, which was confirmed by the results of principal coordinate analysis and population structure. Combining the SCoT and CBDP markers with polymorphic SSR markers may have applications in genetic fingerprinting and association analysis in wheat and its germplasm.

Summary: This study investigates the genetic diversity and structure of European soybean cultivars and American introductions registered in Europe, supporting optimal exploitation of genetic resources. Results show that the European soybean gene pool still has sufficient diversity due to differences in historical breeding practices and relatively short breeding period in Europe.

Summary: The genetic diversity and population structure of upland cotton germplasms in China were analyzed using 26 simple sequence repeat (SSR) markers. A total of 92 distinct bands were amplified from 65 SSR markers, with an average of 3.54 bands per marker. Cluster analysis divided the germplasm into 11 groups, with group 1 further divided into 6 subgroups. Structure analysis revealed three distinct populations with gene exchange between them. These findings demonstrate the genetic diversity and complexity of upland cotton germplasm, providing a foundation for targeted breeding.

Summary: In this study, an ex situ collection of 60 fig accessions from Greece and other Mediterranean countries was established and analyzed using SSR loci. The results showed low allelic variation and high heterozygosity in Greek fig genotypes, indicating extensive outbreeding. Furthermore, there was little correlation between genetic makeup and geographical origin of the fig accessions. An identification key scheme for fig cultivars was developed for cultivar discrimination and intellectual property protection.

Summary: In this study, 217 cultivated radish accessions were genotyped using 24 structure variation markers. The results showed a good polymorphism of these markers and revealed three main populations of radish, which were highly associated with geographical distribution. The high genetic diversity of radish germplasms provides valuable resources for genetic mapping, functional genomic research, core germplasm utilization, and molecular breeding of radish.

Summary: The present study developed genomic simple sequence repeat (gSSR) markers for wild pomegranate using genomic sequences obtained through the Illumina platform. The research revealed high genetic diversity and provided a basis for breeding programs for wild pomegranates. Cross-species amplification demonstrated the transferability of these markers to cultivated pomegranate cultivars and other plant families.

Summary: In this study, the genetic diversity, genetic differentiation, and historical dynamics of the topmouth culter (Culter alburnus) from five river basins in China were analyzed using the mitochondrial DNA COI gene. The results showed that there is polarized genetic diversity in different populations, but without new species differentiation, and significant geographical features, which are important for conservation strategies.

Summary: Population growth and high demand for food production have led to environmental degradation and loss of biodiversity. Conservation of genetic resources is crucial for maintaining species variability, such as Capsicum peppers. This study characterized 69 pepper accessions from Brazil using qualitative and quantitative descriptors and molecular markers, revealing significant genetic diversity among accessions and providing valuable information for breeding programs.

Summary: This study constructed genetic fingerprints for individual identification of sweet potato using molecular markers and morphological markers. A genetic fingerprint database containing 1021 sweet potato germplasm resources was established, showing that Chinese sweet potato germplasm has narrow genetic variation. It was found that sweet potato germplasm resources from Peru have the richest genetic diversity, supporting the view that Peru is the center of origin and domestication of sweet potato varieties.

Summary: In this study, 311 pear accessions from the Lazio region in Italy were genetically characterized using nine SSR markers. The analysis revealed 250 unique genotypes and 14 cases of synonymies. The study also found that some pear accessions had triallelic profiles, indicating the presence of extra alleles. These findings are important for the conservation and management of pear varieties.
