A total of 90 grapevine samples collected in five countries of the Western Balkan region were evaluated for trueness-to-type and kinship relations based on comparative analysis with 1,130 grapevine genotypes held at the INRA "Domaine de Vassal" French Grape Germplasm Repository, using 14 microsatellite markers. In the context of the comparative analysis, twenty-four synonyms/counterparts and the putative parents for twelve Balkan accessions were identified. We discovered five pairs of homonyms, subsequently confirming the identity or...

The Holy Land has a long history of winemaking, widely mentioned in ancient scripts. The Muslim occupation of this region, starting in the 7th century initiated a wine consumption prohibition, resulting in the abandonment of most wine varieties. The renewing of Israeli wine industry in the 19th century was based on international cultivars. Between the years 2011-2014 we conducted a country-wide survey towards the collection and assessment of an Israeli grapevine germplasm collection, including for...

Before the Phylloxera (Daktulosphaira vitifoliae) crisis in Croatia more than 400 grape varieties were under cultivation. Today their number is drastically decreased. Recently, many efforts in the preservation of grapevine biodiversity were undertaken: detailed inventory of varieties in different wine-growing regions, establishing of national and regional collections and their systematic ampelographic and genetic characterisation. This paper shows results of multiannual ampelographic and genetic research concerning Croatian grapevines considered as autochthonous varieties. After identification, many synonyms...

Israeli germplasm: phenotyping and genotyping of native grapevines (Vitis vinifera L.)

D. Rusjan, R. Pelengić, B. Pipan, E. Or, B. Javornik & N. Štajner
In this study 32 grapevine accessions from Israel were phenotyped according to O.I.V descriptors and phyllometry, furthermore genotyped with seven microsatellite loci for the first time for further clarification of their potential biodiversity and phylogenetic grapevine analysis. The results according to the SSR microsatellites suggest that the majority of the studied Israeli grapevine accessions, compared to the international reference varieties, show considerably different genotypes - nine accessions showed a unique (individual) genotype, further three accessions...

Ampelometric evaluation of wild grape (Vitis vinifera L. ssp. sylvestris (C.C. Gmel.) Hegi) accessions in the germplasm collection of FEM-IASMA, Italy

P. Bodor, M. Ladányi, L. Grzeskowiak, M. S. Grando & G. D. Bisztray
In this paper, 45 wild grapevine accessions collected during two consecutive years were compared for 36 ampelometric traits using digital image analysis. The sample set contained male and female individuals from different geographic regions: Germany, North Italy, Central Italy, South Italy, Sardinia and Turkey. The leaf morphological data from the collected samples suggest that geographic origin, gender and vintage could have an effect on ampelometric traits in this species.

Ecological characterization of wild grapevine habitats focused on arbuscular mycorrhizal symbiosis

R. Ocete, I. Armendáriz, M. Cantos, D. Álvarez & R. Azcón
The European wild grapevine, Vitis vinifera L. ssp. sylvestris (Gmelin) Hegi, is cited as a dioecious relative of cultivated vines, so it can play an important role as phytogenetic resource. There is a lack on the knowledge about the susceptibility of wild grapevine to arbuscular mycorrhizal (AM) association. In consequence, the aim of the present work is to confirm the presence of arbuscular mycorrhizal fungi (AM) in the wild grapevine rhizosphere spread in different kinds...

Cluster architecture of old, neglected Croatian grapevine varieties (Vitis vinifera L.)

G. Zdunić, A. Mucalo, I. Budić-Leto, I. Humar, I. Pejić & E. Maletić
Grape cluster architecture is an important trait affecting fruit composition and yield. Damage caused by gray mold (Botrytis cinerea) is directly related to cluster density and some other environmental factors. The aim of this study was to quantify characteristics of fully mature clusters of eleven old Croatian grapevine varieties (Vitis vinifera L.) which so far have not been phenotypically described in detail, and to examine Botrytis cinerea disease severity on their grapes under field conditions....

This study aimed at testing the efficiency of a droplet-vitrification cryopreservation protocol in eliminating selected grapevine viruses. The cryopreservation protocol led to approximately 50 % recovery with cultivar 'Portan' and five international cultivars tested, but very low recovery was noted with Croatian cultivars. GFLV and GLRaV-3, two (economically important grapevine) viruses were eliminated in a high percentage (up to 100 %) of plants regenerated from cryopreserved shoot tips. Virus sanitation was observed as well in...

Rapid stomatal and photosynthetic responses of Vitis berlandieri leaves after petiole excision in water

H. Düring
Excision of petioles of Vitis berlandieri leaves in water caused a transient decline of stomatal conductance within 30-50 s at high and low leaf water potentials. The time of the subsequent recovery of stomatal conductance to the starting point increased with decreasing leaf water potentials (r = -0.969). R is concluded that the rapid increase of pressure in xylem vessels after excision in water is transmitted directly to the epidermis and the stomata bypassing the...

The soil effects on the grapevine root system in several vineyards of the Loire valley (France)

R. Morlat & A. Jaquet
The effects of different soil types on grapevine root distribution are presented and discussed for Loire Valley (France) conditions. Field studies with Cabernet franc/SO 4 root-stock vines showed four main rooting patterns in different soil types. A statistical analysis was used to determine the influence of several physical soil factors on root distribution. The soil water supply appears to have a beneficial effect on the root system. Conversely the penetrometer soil strength, bulk density and...

Detection of arabis mosaic virus using the polymerase chain reaction (PCR)

Ulrike Ipach, B. Altmayer & K. W. Eichhorn
A new method is described for detecting arabis mosaic virus (ArMV) in infected plants. Specific sequences of ArMV-RNA present in total nucleic acid extracts of infected Vitis vinifera or Chenopodium quinoa were initially reverse-transcribed into a complementary DNA (cDNA), then amplified by PCR using specific oligonucleotide-primers. Different primer combinations distinguished between an ArMV infection and an infection with grapevine fanleaf or raspberry ringspot virus. The amount of nucleic acids obtained from 5 mg grapevine leaves...

Application d'une méthode d'électrophorèse pour la caractérisation et la reconnaissance des porte-greffe

J. M. Boursiquot & P. Parra
L'étude par électrophorèse (gel d'amidon) de la glucose-phosphate-isomérase (GPI, EC sur des extraits obtenus à partir des jeunes racines ou de sarments aoûtes a montré que ce type de matériel végétal pouvait être utilise en vue de l'identification des porte-greffe. Pour les racines, les meilleurs résultats ont été obtenus à partir de plants dont le feuillage était en bon état et en début de phase de croissance. L'utilisation de sarments s'est révelée en définitive...

Further studies on the use of molecular probes to grapevine closterovirus A

A. Minafra, M. Russo & G. P. Martelli
Two cloned cDNA probes to genomic RNA of grapevine closterovirus A (GVA) were utilized successfully for the detection of viral sequences in infected herbaceous hosts (Nicotiana benthamiana) and grapevines. One of the probes (pGA112) was complementary to the central part of the viral genome and gave light false positive signals with healthy grapevine extracts, whereas the other (pGA240), which is presumably colinear with the 3' terminus, was virus-specific and hybridized only with infected sample extracts....

Sources of resistance to grapevine bacterial canker disease in Vitis

R. Chand
14 Vitis spp., 7 other Vitaceae and 73 cultivars belonging to Vitis vinifera and V. labrusca were screened under natural and artificial inoculation conditions for their resistance to grapevine bacterial canker disease (GVBCD). Among the Vitis species, V. vinifera was highly susceptible, while others were either resistant or highly resistant. Vitaceae other than Vitis were highly resistant. Among the V. vinifera cultivars, seedless ones were more susceptible than seeded vines. Among seedless cultivars, coloured were...

In vivo development of ovule in seedless and seeded cultivars of grapes (Vitis vinifera L.)- a particular reference to in ovulo embryo culture

Zora Singh & S. J. S. Brar
Ovule development was examined in the three seedless cvs Perlette, Thompson Seedless, Beauty Seedless and the seeded cv. Anab-e-Shahi, to identify the proper developmental stage of the embryo for in ovulo embryo culture. The number of shrivelled ovules started increasing 20 d post anthesis. At the same time, the number of viable ovules started declining in all the seedless cultivars. Amongst seedless cultivars, the growth of ovules was least in cvs Thompson Seedless and Beauty...
