Strawberry cultivars in current commercial use have a very narrow genetic base and reduced morphological and genetic diversity that puts them at risk from disease and climate change. [...] Key Method A comprehensive catalogue of descriptors drawn up by UPOV and IPGRI served as the basis for evaluation of 108 cultivars in a field trial.Expand

Phenotypic and genotypic characterization in the collection of sour and duke cherries (Prunus cerasus and ×P. ×gondouini) of the Fruit Genebank in Dresden-Pillnitz, Germany
Examination of sour and duke cherry cultivars of the Fruit Genebank of the Institute for Breeding Research on Fruit Crops revealed that color descriptors as well as the fruit size and weight, the organoleptic quality and the two descriptors related to the abscission between fruit and stalk were the most effective parameters to discriminate genotypes.

Pomological and biochemical characterization of European currant berry (Ribes sp.) cultivars
Great diversity in this currant collection showed its good potential for fresh and processing usage, and further breeding programs, as well as high discrimination capabilities of variables measured. Expand
Phylogenetic Relationships of Nine Cultivars of Strawberries (Fragaria spp.) Based on Anatomical and Morphological Characters
Results showed that there were 37 anatomical and morphological characters that play a role in the characterization of nine cultivars where the shape of the fruit and type of attachment of the flowers were the main characters distinguishing among the nine cultivar studied. Expand
Characterization of strawberry genotypes with low chilling requirement for cultivation in tropical regions
The PCA and selection index results indicate the reliability of the multivariate analysis for selecting superior strawberry genotypes for cultivation in tropical regions and highlighted the genotypes RVCA16M-1, RVDA11M-3, RVda11M -4, and RVDA 11M-25 as superior for most of the evaluated traits compared with the commercial cultivars 'Albion' and 'Monterey'.

Detecting strawberry cultivar misidentification in the Philippines using single nucleotide polymorphism markers from the anthocyanin reductase gene
The molecular markers developed in this study could assist in future cultivar verification efforts, germplasm management, and breeding programs. Expand
Analysis of yield stability of strawberry varieties and hybrids
The aim of this work was to estimate the yield stability of varieties and hybrids by the methods of multivariate statistical analysis and identify the best genotypes by using the two-factor analysis of variance and hierarchical cluster analysis according to the Ward’s method. Expand
Introgression and confirmation of everbearing trait in strawberry (Fragaria x ananassa Duch.).
It could be revealed that the targeted everbearing trait is governed by a dominant gene(s) in the subjected strawberry genotypes and would be successfully employed in DNA fingerprinting of strawberry under various crop improvement programme. Expand
German Fruit Genebank – looking back 10 years after launching a national network for sustainable preservation of fruit genetic resources

Estimation of the frost resistance of the strawberry
As a result of the experiment, it was found that an increase in bound water and a decrease in free water in the leaves in the autumn are characteristic of strawberry plants against the background ofExpand

Assessment of the genetic and phenotypic diversity maintained in apple core collections constructed by using either agro-morphologic or molecular marker data
Overall, the kind of data used to constitute a core collection had little influence on the phenotypic and genetic diversity retained, so in the case of apple collections the use of molecular markers is preferable for this task because they allow a rapid and reliable characterization. Expand
Structured diversity in octoploid strawberry cultivars: importance of the old European germplasm
The structure within the studied collection was mainly explained by the pedigree and the year of release than the geographical origin of cultivars, and diploid markers identified can be used without ambiguity in phylogenetic and diversity studies, because they are genome-specific. Expand
Analysis of Apple Germplasm in Northwestern Spain
The main objectives of this work were to evaluate the inter- and intracultivar variability using morphological characters and isoenzymes, to classify the accessions according to the main sources of variability, and to identify repetitions in the germplasm bank. Expand
Morphological variation within a sour cherry collection
It may be possible to select sour cherry hybrids approaching the tree and fruit size of either progenitor species, as well as the potential of certain cultivars and hybrids as parents. Expand
Phenotypic diversity and relationships of fruit quality traits in apricot (Prunus armeniaca L.) germplasm
Year-by-year variations were observed for some pomological traits such as harvest date, flesh colour, fruit weight, firmness and soluble solids content and a high correlation was found among some apricot quality attributes. Expand
Analysis of apricot germplasm from the European ecogeographical group
Morphological, phenological and fruit quality traits of 55 apricot cultivars, including the most important clones grown in Spain, France and Italy, were evaluated using principal component analysis.Expand

The PVS2 vitrification protocol with cold acclimation will be applied as the standard method for cryopreservation of Fragaria cultivars and wild species. Expand
Analysis of morphological, pomological and yield characteristics of some apricot germplasm in Turkey
The Levent apricot type possessed a substantially late ripening with a total period of 190–200 days for fruit development, a characteristic that makes this apricots type highly suitable for breeding studies. Expand
A Method for Evaluating the Morphological Diversity of Strawberry Leaves in Natural Populations
A method for comparing polymorphic characters is proposed and the morphological diversity of strawberry leaves is evaluated, showing how different sets of real leaves from individual populations differ in being located in different parts of this space. Expand
Core collections: a practical approach to genetic resources management
Large numbers of entries are now lodged in many of the world's germ-plasm collections of crop and pasture plants, and the problems of how best to conserve it and how to use it in plant breeding have intensified. Expand
