TLDR
The overall arrangement of cultivars suggests considerable phenotypical and genetic variability in studied germplasm collection, and may be useful for further utilization of available genetic resources in gene bank managers, growing and breeding.Abstract:
The objective of this study was to evaluate diversity and relationships among
grapevine cultivars from the Serbian gene bank in Sremski Karlovci, and to
identify the most useful variables for discrimination. A total of 54
grapevine cultivars have been studied. During the period 2000-2005, twelve
quantitative and qualitative characteristics were evaluated using OIV
categories to each trait. Characterization was done using multivariate
statistical analyses: cluster and principal component analysis (PCA), Based
on cluster analysis cultivars divided into three major groups and the
clustering pattern was related to the classical eco-geographical grouping:
occidentalis, pontica and orientalis. Beside geographic origin clustering
position of cultivars throughout the dendrogram was related to main uses. The
major part (70.1%) of the total variation presented was explained by four
principal components. PC1 is highly correlated with the bunch and berry size
and PC2 with the density of prostrate hairs of young shoot tip and the
density of prostrate hairs between veins on the lower side of mature leaf.
The overall arrangement of cultivars suggests considerable phenotypical (and
presumably genetic) variability in studied germplasm collection. Furthermore,
obtained results may be useful for further utilization of available genetic
resources in gene bank managers, growing and breeding. [Projekat Ministarstva

The scientific information activity of Bioversity International: the descriptor lists.
TL;DR: This paper explores the history of descriptor lists (DLs)—scientific standards for documenting plant genetic resources—which have been published by Bioversity International since 1976 and presents an analysis of data collected through questionnaires and web statistics on the impact of DLs in order to understand their use by major stakeholders.

A multivariate approach for the ampelographic characterizations of Algerian grapevine genotypes (Vitis vinifera L.): Insights into conservation and commercialization
O. Bounab,O. Bounab,Ziane Laiadi +2 more
TL;DR: The results obtained confirmed the synonymy between varieties already found previously by molecular SSR markers in particular between both varieties as Bouaber des Aures and El wali, despite the close convergence between them, especially in ampelographic quantitative measured criteria.

TL;DR: In this article, the results of the DNA analysis should be combined with the ampelographic descriptors, in order to select grapevine varieties with desirable viticultural and oenological traits.

TL;DR: The overall organization of genetic diversity suggests that the germplasm of cultivated grape represents a single complex gene pool and that its structure is determined by strong artificial selection and a vegetative mode of reproduction.

TL;DR: Using 20 SSR markers well scattered across the 19 grape chromosomes, 4,370 accessions of the INRA grape repository at Vassal revealed 2,836 SSR single profiles, suitable for routine characterization and will be valuable for germplasm management.

TL;DR: Evidence is provided that the cultivated compartment of Vitis vinifera L. is genetically structured, and the finding of a large portion of admixed genotypes may be the trace of both large human-mediated exchanges between grape-growing regions throughout history and recent breeding.
