“…Several studies have applied PCA to assess phenotypic relationships among important fruit tree crop such as European plum (Prunus domestica L. subsp. domestica, Sarigu et al, 2017), almond (Khadivi-Khub and Etemadi-Khah, 2015) and peach (Engel et al, 2015).…”

To know the relationships between phenotypic and genetic variables in a germplasm collection of fruit crops is useful a pre-breeding and cultivar distinctness. A core collection of 23 peaches/nectarines (Prunus persica (L.) Batsch), and 16 Japanese plum (Prunus salicina Lindl. var. salicina) cultivars were evaluated for 33 and 29 characteristics (botanical/ productive) respectively during two growing seasons. Also, eight specific simple sequence repeats (SSRs) markers were analyzed in both species. Principal components analyses revealed seven characteristics (related to the size of the fruit and the firmness of the pulp) as the most important for the 23 peach/nectarine cultivars and four characteristics (yield, fruit size, soluble solids, and harvest time) for the 16 Japanese plum cultivars. These analyses revealed three cultivars of peaches (Diamond Princess, Dixon, and Dr. Davis) and three of nectarines (Ruby diamond, Artic sweet, Summer fire) with the highest values for fruit size and pulp firmness. Four Japanese plum cultivars (Angeleno, Flavor Rich, Red Heart, and Pink Delight) showed the highest values of yield, fruit size, soluble solids, and harvest time. Elite germplasms to carry out a breeding program were identified from both the phenotypic and genetic analysis. Additionally, cultivar-specific SSR alleles were identified and are a relevant tool for cultivar distinctness.

“…Characterization is carried out by using standardized descriptors, mainly those from ECPGR [83][84][85], UPOV or the National Guidelines [16]. Phenology of blooming and harvest are the most frequently recorded traits, and historical series are used to assess the effect of climate change in almond [86], apple [87], sweet cherry [88] and peach [89,90]. Traits related to tolerance to abiotic [91] and biotic [92,93] factors are increasingly evaluated in many collections, as well as fruit quality, including secondary metabolites with healthpreserving properties [94].…”

Conservation, characterization and exploitation of agrobiodiversity are key factors to guarantee food security and face future challenges such as climate changes. These issues are the subject of a series of international agreements, such as the Convention of Biological Diversity, with its Nagoya Protocol, and the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) adopted in 2001 and entered into force in 2004. Italy ratified the Treaty in 2004 and instituted a long-lasting program, RGV-FAO, to implement it. CREA is one of the three organizations involved in the RGV-FAO Program, together with the National Research Council (CNR) and Reti Semi Rurali. CREA maintains a total of 40,186 accessions including cereals, vegetables, fruits, forages, industrial crops, forest and woody crops, medicinal and aromatic plants, and their wild relatives. Accessions are conserved using different ex situ conservation systems (seeds, in vivo plants, vegetative organs and in vitro plantlets), and characterized using genetic, morpho-phenological and/or biochemical methods. Herein, we will present the CREA long-lasting program RGV-FAO with some examples of the use of plant genetic resources in breeding programs, including molecular approaches. Some critical issues related to access and benefit sharing in PGRFA, such as the Nagoya Protocol and the Digital Sequence Information, will be discussed, highlighting their potential impact on food security and on the advancement of knowledge.
