“…Main chemical composition parameters for the analyzed samples is presented in Table 1. Some of the parameters differ significantly between cultivars, and others are similar regardless of the cultivar, results reported also in the literature studies (Botu et al, 2012;Ravelonandro et al, 2013;Hȃrţa et al, 2016;Pop et al 2018).…”

Plums are low-calorie fruits with a low glycaemic index score. Prunus domestica L. is one of the tree fruits threatened by Plum pox potyvirus (PPV), a quarantine disease that causes fruit loss to plums and other stone fruits. HoneySweet is a plum tree created to be resistant to this virus. Beside genetical determinations, chemical composition and nutritional value are important for a future acceptance in the cultivation of this type of fruit trees. Two conventional (Renclod Althan and Stanley) and one genetically engineered (HoneySweet) plum fruits were evaluated for the nutritional value determination. The analyzed samples showed nutritionally valuable features. HoneySweet variety had a balanced content of individual carbohydrates. The total lipid content had values quite close to the HoneySweet and Stanley varieties, far superior to Renclod Althan variety. HoneySweet transgenic plum had the highest total protein content. Also, HoneySweet variety is distinguished by a balanced protein and lipid content. By comparing the three analyzed varieties from the perspective of the most important physic-chemical nutrients (carbohydrates, proteins and lipids), the highest nutritional value was registered in Stanley variety, closely followed by HoneySweet, and then by Reine Claude d’Althan.

“…Plum is considered an important fruit tree crop of the temperate climate and most of the modern cultivars belong to the hexaploid (2n = 6x = 48) European plum (Prunus domestica L.). This species might have diploid P. cerasifera (cherry plum) and tetraploid P. spinosa (sloe) components in the genome structure or can be a descendent of P. cerasifera resulting from polyploidization (Botu et al, 2012).…”

“…Plum cultivation has a historical tradition and economic implication for the South-eastern European countries including Romania. The European plum (Prunus domestica L.) is considered an important indigenous species in the Balkans and thousands of local biotypes were grown here for centuries and being part of the local culture (Botu et al, 2012). In this context, the identification and characterization of the valuable plum genetic resources based on modern methods (SSRs and SNPs markers, HRM analysis) is an important goal for germplasm evaluation in the Balkan countries (Halapija Kazija et al, 2014;Merkouropoulos et al, 2016).…”

In Romania, Prunus genetic resources are held in collections located mainly in research and development institutes or in fruit growing stations. A possible disadvantage of the utilization of these resources for genetic studies and also for breeding programmes is the lack of reliable data for correct identification and characterization of accessions. In this study, 27 plum accessions from Râmnicu-Vâlcea Fruit Research Station, Romania, were assessed using nine SSR markers generating a total of 134 distinct alleles, with an average of 14.89 alleles per locus. Differentiation between the Romanian plum cultivars and international reference cultivars was low, but significant, for all the nine loci (Fst = 0.012; P < 0.0001). Plum accessions were grouped in two clades, both including old and newly developed Romanian cultivars and also international reference cultivars, according to an UPGMA dendrogram. Bayesian analysis of genetic structure revealed significant admixture among examined accessions while principal coordinate analysis performed on the molecular data illustrated a substantial dispersion of old and newly developed Romanian plum accessions in the three-dimensional PCoA scatter plot. These results could make them attractive for future breeding programs and long-term conservation strategies based on identified genetic dissimilarities.

“…Conventional methods: Conventional breeding methods are still largely used in the majority plum breeding programs, and the most important of these are intra and interspecific hybridization and open pollination. These methods contributed in a substantially way to modify the genetic structure of quantitative traits of new plum cultivars and rootstocks [3,10,20,28].…”

Worldwide, plum is one of the main species, occupying an area of about 2,600,000 ha and ensuring production about 11,700,000 tons. Even though there are over 6000 plum cultivars belonging to 19–40 species, there is still the need to create new cultivars due to the demands of growers and consumers. In addition, the large plum-growing countries (Romania, Serbia, Germany, Bulgaria, etc.) have decreased production due to plum pox virus (PPV) attack. Therefore, these countries developed breeding programs with the following objectives: resistance/tolerance to PPV, productivity, fruit quality, late blooming, self-fertility, different ripening times, short growing period, spur fructification, etc. Using different breeding methods (controlled hybridization, open pollination, selection in wild population on Prunus sp., and mutagenesis), in the last years, over 450 plum cultivars were released, from which 70% represent European cultivars and 30% Japanese cultivars.
