Genetic diversity of a Serbian grapevine germplasm collection based on morphoagronomic characteristics

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 nauke Republike Srbije, br.

Ampelographic and molecular characterisation of grapevine varieties in the gene bank of the experimental vineyard ‘Radmilovac’ – Serbia

“…Today, there are three major ampelographic collections for the Vitis genus in the Serbian plant gene bank: i) Sremski Karlovci, an experimental vineyard within the University of Novi Sad's Faculty of Agriculture containing a total of 737 samples, ii) Radmilovac, an experimental vineyard within the University of Belgrade's Faculty of Agriculture containing a total of 659 samples, and iii) The Centre for Viticulture and Wine Production at Niš containing a total of 336 samples (Nikolić et al, 2021). Results obtained by several authors (Rakonjac et al, 2014;Štajner et al, 2014) have confirmed high levels of diversity among cultivated varieties.…”

Screening of Galician grapevine varieties by SNPs, phenotypic traits, and phytopathology

“…In the present study, ANOVA, principal components, and genetic marker analyses were used to identify and classify the varietal diversity of the EVEGA Grapevine Germplasm Bank. Ampelographic descriptions, together with the identification of plant material using DNA markers, are the first steps in the characterization of grapevine germplasm collections (Muganu et al, 2009;Rakonjac et al, 2014;Zombardo et al, 2021). High diversity was found at a morphological level, as only 6 out of 74 ampelographic and ampelometric parameters studied were homogeneous for all varieties.…”

Characteristics of newly created grapevine varieties Vozd and Vladun

“…Although modern viticultural production imposes the need to create better grapevine varieties, their spreading and propagation in nurseries is preceded by detailed verification, comprehensive assessment of value, and finally official recognition and their inclusion on the List of varieties and hybrids of agricultural and forest plants of the Republic of Serbia. RAKONJAC et al (2014) state that morphological classifications provide useful guidelines to variety relations, developing further insight for plant breeders and gene bank managers. The first step in this study is to ampelographically described existing varieties.…”
