“…Our work also indicated that a reduced number of SSRs is sufficient to efficiently discriminate plum varieties [20]. We observed very few high pair-wise similarities (i.e., >0.9), which is consistent with the lack of sports and/or Essentially Derived Varieties (EDV) originating from formal breeding [49]. A reduced number of nuclear SSRs offers obvious advantages for screening large populations however, we cannot exclude that a higher number of SSRs or the implementation of DNA sequence-based approaches [50], may be necessary to discriminate very similar varieties or to solve cases of putative homonymy.…”

“…Our work indicates that morphological measurements of the fruits are very useful for the description of local varieties, also because their use does not require sophisticated technologies. In addition to the known advantages of molecular fingerprinting, the combination of molecular and morphological data for the classification of traditional plum varieties is probably necessary to separate closely related accessions and sports, or to select variants and clones [49].…”

Molecular and Phenotypic Diversity of Traditional European Plum (Prunus domestica L.) Germplasm of Southern Italy

et al. 2019

The European plum (Prunus domestica L.) is a worldwide distributed tree species. Italy has an ample number of traditional varieties, but many are neglected and at risk of extinction. This germplasm is still cultivated in rural areas in spite of the EU-28 crisis of the stone fruit sector. Traditional European plum varieties remain poorly characterized, strongly limiting their promotion in local markets, use for farm diversification, and exploitation for local gastronomic products. In this study, we carried out an investigation of the morphological and genetic diversity present in an ex-situ collection of 29 traditional varieties of P. domestica of the Campania region (Southern Italy). The combination of five continuous and five categorical fruit traits allowed us to phenotypically distinguish all the varieties. Similarly, the Simple Sequence Repeats (SSRs) employed (five genomic and five deriving from Expressed Sequence Tags) identified a unique molecular profile for each variety. Moreover, the data indicated that the phenotypic and molecular investigations provided different clustering, suggesting that the two analyses sampled different sources of diversity. The number and the distribution of the scored phenotypes as well as the indices of genetic diversity imply the presence of a wide-ranging variation, which may sustain the development of high-value, niche market products. Our work provided evidence that the implementation of measures for a combination of ex-situ and on-farm conservation of traditional European plum varieties should be preferred to avoid the loss of an ample diversity.

“…The number of SSR primer pairs used in the study is higher or equal to other recent molecular studies on the European plum (Decroocq et al, 2004;Horvath et al, 2011;Xuan et al, 2011;Halapija Kazija et al, 2014), albeit lower than the 16 SSRs used by Gharbi et al (2014). However, Gharbi et al (2014) analyzed a group of genetically very similar 'Reine Claude Verte' plum accessions, hence the need for a higher number of SSR markers.…”

“…European plums are cultivated in colder climates [92], showing higher chilling requirements (579-1323 CH) than Japanese plums (118-685 CH) ( Tables 5 and 6). The chilling requirements of European plum ranged from 579-678 CH for 'Reine Claude d'Oullins' to 1116-1323 CH for 'Reine Claude Noir' [93]. There is no data available on heat requirements in this species.…”

Chilling and Heat Requirements of Temperate Stone Fruit Trees (Prunus sp.)

et al. 2020

Stone fruit trees of genus Prunus, like other temperate woody species, need to accumulate a cultivar-specific amount of chilling during endodormancy, and of heat during ecodormancy to flower properly in spring. Knowing the requirements of a cultivar can be critical in determining if it can be adapted to a particular area. Growers can use this information to anticipate the future performance of their orchards and the adaptation of new cultivars to their region. In this work, the available information on chilling-and heat-requirements of almond, apricot, plum, peach, and sweet cherry cultivars is reviewed. We pay special attention to the method used for the determination of breaking dormancy, the method used to quantify chilling and heat temperatures, and the place where experiments were conducted. The results reveal different gaps in the information available, both in the lack of information of cultivars with unknown requirements and in the methodologies used. The main emerging challenges are the standardization of the conditions of each methodology and the search for biological markers for dormancy. These will help to deal with the growing number of new cultivars and the reduction of winter cold in many areas due to global warming.Agronomy 2020, 10, 409 2 of 32 (2.4 million t in 0.4 million ha), almond (2.2 million t in 1.9 million ha) and sour cherry (1.2 million t in 0.2 million ha) [2].Stone fruit trees, like other temperate woody species, need to accumulate a cultivar-specific amount of chilling during winter to overcome dormancy and then experience warm temperatures to finally flower in spring [3][4][5]. These conditions the adaptation of species and cultivars to each region [6] and it is the main drawback for their extension to warmer latitudes [7]. Knowing the temperature requirements of a cultivar can be useful for growers to anticipate the future performance of their orchards and to design new orchards taking into account the predicted global warming [7][8][9]. In this work, the available information on chilling-and heat-requirements of cultivars of the most cultivated stone fruit crops (almond, apricot, peach, plum and cherry) is reviewed, paying special attention to the approach used for the determination of breaking dormancy, the method used to quantify chilling and heat temperatures, and the place where the experiments were conducted. There is extensive information available about chilling and heat requirements that has purposefully been omitted from this review. We have only included those studies that a) obtained results by using an experimental methodology (i.e., transferring shoots into a growth chamber sequentially during winter) or computational/statistical approaches that relate flowering dates to temperature data over a sufficiently long time series, and b) quantified chilling and heat temperatures using the common models (Chilling Hours model, Utah model or Dynamic model for chilling requirements, Growing Degree Hours for heat requirements).
