“…Apparently many morphological parameters that are assessed in cultivar identification show unexpected plasticity possibly due to environmental influence or the age of plant tissue. Barth et al (2009) found similarly differences between the clustering based on microsatellite genotypes and phenotypes in a recent survey of another clonally propagated woody plant, Vitis vinifera ssp. sylvestris.…”

The Finnish national sour cherry germplasm collection was established in the end of 1980s following collection missions in Southern Finland. The original plantation consisted of 122 trees representing 77 accessions of locally adapted cherry material. Cultivar names of the collected samples were not known, and they were registered according to the collection site. Phenotypical observations according to the Nordic Genebank instructions were recorded in 1992, 1993 and some repetitions were made in 2003. In 2005 leaf samples were collected from the 52 still remaining accessions for a microsatellite (SSR) DNA marker analysis. DNA analysis distinguished 28 genotypes within the studied material. Two large groups of accessions sharing identical genotype, consisting of 18 and 20 accessions, were detected, one in the amarelle and one in the morellocultivar group, respectively. Several cultivar group specific SSR markers were found. Clustering analysis of the phenotypical characteristics supported the division into two cultivar groups. Replicate trees of one accession, or accessions representing one SSR genotype, clustered together only occasionally indicating some level of plasticity in the observed descriptors. Our findings indicate that only a few sour cherry clones have been successful and commonly distributed in Finland. The results were taken into account when selecting accessions for long term conservation in the national germplasm collection.

“…When the analysis was implemented with other secondary descriptors, the ampelographic traits showed moderate variation. It has to be considered, however, that morphological parameters (especially those that refer to leaves) are influenced by environmental conditions and the age of the tissues, and this could determine phenotypic variation, also without genetic diversity (Barth et al, 2009). In order to restrict this aspect, the ampelographic data have been collected by the same operators and on the same plants under similar cultural condition.…”

To characterise 31 different Aglianico accessions randomly collected in Southern Italy, 30 ampelographic descriptors, 13 SSRs and 10 AFLP primer combinations were analysed. An appreciable variation of ampelographic descriptors was revealed mainly by mature leaf traits, while very few variations were recorded for shoot and berry traits. Similarly, all SSR loci revealed molecular monomorphism and AFLPs with a very high genetic similarity (Dice coefficient) among all the accessions considered. One of the aims of this study was to clarify the genetic assessment of Aglianico Nero and Aglianico del Vulture Nero, since they are registered as two different cultivars with distinct varietal codes at the Italian Register of Grape Varieties. Registered Aglianico Nero and Aglianico del Vulture Nero were included in the analyses, compared and used as reference material. Our plants showed that all the accessions tested, independent from the biotype, and the two registered cultivars belong to the same genotype, suggesting that, as reported by the Vitis International Variety Catalogue, a case of synonymy occurred between Aglianico Nero and Aglianico del Vulture Nero. These cultivars could therefore be considered as a single cultivar. Moreover, the AFLP data revealed a partial match between morphological and molecular data, showing that the AFLP molecular method was able to discriminate between different accessions belonging to the same cultivar.

“…The Précis d'Ampélographie Pratique by Galet (1952) can be considered the reference manual in ampelography, and many of the descriptors described there have been adopted by international organizations (like IPGRI and OIV) for the official description of grape varieties and Vitis species. Although the use of molecular markers is recommended for grapevine identification, ampelography provides relevant morphological and agronomical information for characterization studies, breeding programs and conservation purposes (Barth et al 2009;García-Munoz et al 2011;Lamine et al 2014). Nevertheless, the use of diverse (but sometimes highly correlated) ampelographic descriptors comprising shoot, leaf, cluster and berry traits yield large datasets that need to be treated in a proper way.…”

Due to its unique historical and geographical emplacement, grapes have been cultivated in the Syrian Arab Republic for more than 5000 years, so the characterization of its local genetic resources is paramount for understanding grapevine natural diversity. In this work, different local Syrian table grape cultivars were characterized for 42 traits related to plant phenology, shoot, leaf, cluster, berry and juice composition. A series of multivariate analyses were sequentially performed, and five highly-discriminant traits were identified as the most discriminant ones (shoot internode length, berry weight, berry elongation, 100-seed weight and juice titratable acidity). The clustering of the cultivars according to these five traits revealed that some local Syrian cultivars share similitude with some worldwide grown cultivars, suggesting their potential as new genetic resources for the development of new high-quality table grape varieties, and indicating the needing of specific preservation programs aimed to avoid the loss of endangered genetic local resources. Besides, the statistical multivariate pipeline followed in this work is proposed as an efficient one for the selection of ampelographic traits for the discrimination of grapevine cultivars.
