“…The soil was dug from 0-30 cm depth after removing the living plants and the layer of plant debris. Agrochemical analyses of soil samples were performed at the Laboratory of Agrochemical Analyses of the Lithuanian Research Centre for Agriculture and Forestry (Kaunas, Lithuania) according to certified procedures and protocols (volunGevičius et al, 2015). The following agrochemical parameters were analysed: quantity of humus (%), pH (in water solution, mol/l, in KCl suspension), the content of phosphorus (P 2 O 5 ), potassium (K 2 O), total nitrogen and total carbonates (CaCO 3 ) (mg/kg).…”

“…Therefore, we had a question what factors determine the size of hips and sepals? The hip size is an essential reproductive trait, because larger hips usually contain more seeds, which play a vital role in the spread of R. rugosa over significant distances and invading new areas (Bruun, 2005;kollmann et al, 2009;tonG et al, 2017;ZHanG et al, 2018). Although persistent sepals do not play an essential role in reproduction, they are an integral part of the hip.…”

Rosa rugosa is among the most invasive species in Europe, and it is considered a severe threat to the diversity and stability of coastal habitats. In Lithuania, it is a widespread invasive species occurring in coastal and inland areas. This research aimed to estimate the variation in R. rugosa hip and sepal parameters within and among sites from coastal and inland areas, and investigate the effects of environmental factors on the hip and sepal sizes. Field studies were performed at four coastal and three inland sites in 2008, and the studies were repeated in 2016. We collected 100 mature hips at each site and measured the hip width, hip length and sepal length. We analysed variation in hip and sepal parameters between the study years, and the effect of meteorological factors and agrochemical properties of the soil on hip and sepal sizes. This study revealed significant variation in R. rugosa hip width, hip length and sepal length among the studied sites. The largest hips and sepals were found in the coastal habitat at the Smeltė site, whereas the smallest hips and sepals were recorded in inland habitat at the Staviškės site, where R. rugosa occurred in woodland. The comparison of hip and sepal sizes at the same sites during two study years revealed irregular variation. Mean hip width and mean length of sepals in 2008 were significantly more prominent than in 2016, whereas no significant differences in hip length were found between the study years. The content of phosphorus in the soil negatively correlated, whereas the content of carbonates positively correlated with the sepal length. A strong negative relationship was found between the sunshine duration and hip length and width ratio. However, the revealed relationships of the hip and sepal parameters with the environmental factors could be a coincidence or a result of the cumulative effect of the multiple factors’ interaction and should be investigated separately.

“…As we know now, domesticated categories vary in flower colours and types. The wild category varied much less than the domesticated category, but there were still some small variations in growth habits, leaves, thorn density, and seed weight [ 13 ]. In previous studies, domesticated roses ( Rosa ) underwent frequent hybridization and backcrossing, in which several wild species were involved in early breeding.…”

Background Rosa rugosa is a shrub that originated in China and has economic and ecological value. However, during the development of R. rugosa, the genetic background was chaotic, and the genetic structure among different wild populations was unclear, as well as wild and cultivated accessions. Here, we report whole-genome resequencing of wild and cultivated R. rugosa accessions. Results A total of 19,041,284 SNPs were identified in 188 R. rugosa accessions and 3 R. chinensis accessions by resequencing. Population genetic analysis revealed that cultivated and wild groups were separated very early. All R. rugosa accessions were divided into 8 categories based on genetic structure: (1) Weihai, Yantai, and Liaoning category, (2) Jilin category, and (3) Hammonasset category (above three are wild); (4) traditional varieties, (5) hybrids between R. rugosa and R. chinensis, (6) Zizhi Rose, (7) Kushui Rose, (8) hybrids between R. rugosa and R. multiflora. We found that the heterozygosity and genetic diversity of wild accessions were generally lower than those of cultivated individuals. The genes that were selected during cultivation were identified, and it was found that these genes were mainly related to environmental adaptation and growth. Conclusions The Jilin population was the oldest population and later migrated to Liaoning and then migrated to Yantai and Weihai by sea regression in the Bohai Basin. The Hammonasset naturalized population probably originated from the Jilin population and then experienced separate differentiation. The long-term asexual reproduction pattern of R. rugosa decreased genetic diversity in the wild population. During R. rugosa cultivation, the ancestors of the Jilin population were involved in breeding traditional varieties, after which almost no wild individuals were engaged in breeding. However, in recent decades, cross breeding of R. rugosa started the utilization of wild germplasms. In comparison, some other species play important roles in variety formation. Few genes related to economic traits were selected, suggesting no directional domestication in the R. rugosa cultivation process.

A method for constructing core-germplasm of Rosa rugosa in China based on molecular marker data was probed and the optimum core germplasm was established. Studies were initiated to analyze the genetic diversity of 120 rugged roses from 6 different Chinese source populations based on CDDP marker, and a preliminary construction of the core collection was established using stepwise UPGMA clustering sampling method. The 26 core collection resources of R. rugosa collections in China have 20% germplasm samples of initial collection, the retention ratio of polymorphic loci, effective number of alleles (Ne), Nei's genetic diversity (H) and Shannon information index (I) were respectively 97.52%, 104.16%, 108.38% and 106.18%. The results of t-test showed that no significant difference was found in genetic diversity indexes between the core collection and the original collection. These results also demonstrated that the core collection could stand for original collection excellently. The results show that CDDP molecular technology can be successfully applied to the construction of core germplasm resources of rugged roses.
