“…This result is similar to the structure of the tomato population in the fresh market described by Sim et al (2011). Of course, introduced varieties are mainly determined by human activities rather than natural factors (Guo et al 2021). These cultivated varieties may then hybridize with wild tea plants due to geographical distance, weather in uences (Hegland et al 2009;Malyshev et al 2022), and wildlife (Huo et al 2019;Godley et al 1967;Gervasi et al 2017).…”

As a renowned tea with a historical signi cance in China, Gushan semi-rock tea originated from the Gushan Mountain in Fujian, China. This study describes the genetic diversity, population structure, and distribution characteristics of 76 tea samples collected from Gushan Mountain and neighboring regions, using single nucleotide polymorphism (SNP) markers. The results show that the average information index (I) is 0.490, the average observed heterozygosity (Ho) is 0.384, the average expected heterozygosity (He) is 0.329, and the average xation index (F) is -0.132. The genetic variation mainly comes from intraregional variation, which accounts for 82% of the total variation. Furthermore, there is a closer connection between tea plants in Southern, Northern, and Eastern Fujian. The frequency of genetic exchange between tea plants in the Gushan semi-rock tea and those in Southern, Northern, and Eastern Fujian is relatively low, showing obvious uniqueness. The ndings of this study help ll the gap in tea genome research in the Gushan semi-rock tea and provide valuable information on the genetic diversity of tea resources in Gushan area. The results can be utilized in future genomics, phylogeny, and arti cial breeding programs aimed at developing new tea varieties.

To screen and evaluate excellent blackberry cultivars and strains, 17 indexes of plant growth and fruit horticultural and nutritional characteristics were measured, 20 simple sequence repeat (SSR) markers were analyzed, the fingerprints of 23 blackberry cultivars and strains were constructed, and the processing characteristics of 10 excellent cultivars and strains were evaluated. The results showed that ‘Chester’ and ‘Shuofeng’ had the highest plant yield (6.5 kg per plant), of which the ‘Chester’ fruit also had the highest hardness (2.78 kg/cm2). ‘Kiowa’ had the highest single fruit weight (10.43 g). ‘10-5n-2’ had the highest total anthocyanin content (225.4 mg/100 g FW) and total polyphenol content (3.24 mg/g FW), but a low plant yield. These results suggest that ‘Shuofeng’ and ‘Chester’ are the top two blackberry cultivars planted in Nanjing, with the best growth and comprehensive quality. Moreover, a total of 119 alleles were detected with an average number of 6 alleles per locus. The polymorphism information content (PIC) was 0.374~0.844, with an average of 0.739, indicating a high genetic diversity among the 23 blackberry cultivars and strains. This study provides insight into the plant growth, fruit characteristics and genetic diversity of the 23 blackberry cultivars and strains, and is thus conducive to the protection and utilization of blackberry cultivars and strains.

Local germplasm resources are the main component of the germplasm resources of tea trees. However, the protection is limited currently in China for local germplasm resources of tea trees. There is no comprehensive and systematic method for collection and protection. This study has created a new method for collecting and protecting local germplasm resources of tea trees. According to the distribution and area of tea trees planted in each tea-producing area, we planned and arranged sampling points, and one sample from each sampling point was collected and planted in a resource garden for preservation. As a case study of Anhui Province, the first germplasm resource garden of tea trees was established comprehensively with the application of this method, at a systematic provincial level. There are 920 samples collected and preserved, nearly 100,000 individual plants. The proportion of samples is close to the proportion of local tea garden areas in various regions of Anhui Province. By applying this method to establish a resource garden, the genetic diversity of local germplasm resources of tea trees is maximally preserved. The preserved resources are the material basis for the future breeding of new tea varieties, analysis of genetic relationships and population structure of germplasm resources, and gene search.
