Study and parentage analysis of old Albanian grapevine cultivars by ampelography and microsatellite markers

The number of old grapevine cultivars in Albania, originated in the country or introduced over many centuries and adapted to the conditions of the country, is huge. Because numerous cases of homonymy and synonymy exist, the interest for variety recognition is high. Investigation of these cultivars aptitudes is related to identification of desired characteristics and their utilization. In the framework of COST Action FA1003, trueness to type assessment of 13 old Albanian cultivars was undertaken including morphologic description and genetic fingerprinting. Parentage relationships were studied as well. The selected cultivars are of interest for their antiquity, for high production and distinctive organoleptic features. The ampelographic study of these cultivars supported confirmation of the results obtained by genetic profile comparison with seven SSR-marker databases and the European Vitis Database. In summary 12 unique genotypes, four parent-offspring relationships and one full parentage were found

Molecular characterization of old local grapevine varieties from South East European countries

South East European (SEE) viticulture partially relies on native grapevine varieties, previously scarcely described. In order to characterize old local grapevine varieties and assess the level of synonymy and genetic diversity from SEE countries, we described and genotyped 122 accessions from Albania, Federation of Bosnia and Herzegovina (B&H), Croatia, Macedonia, Moldova, Montenegro, Republika Srpska (Bosnia and Herzegovina) and Romania on nine most commonly used microsatellite loci. As a result of the study a total of 86 different genotypes were identified. All loci were very polymorphic and a total of 96 alleles were detected, ranging from 8 to 14 alleles per locus, with an average allele number of 10.67. Overall observed heterozygosity was 0.759 and slightly lower than expected (0.789) while gene diversity per locus varied between 0.600 (VVMD27) and 0.906 (VVMD28). Eleven cases of synonymy and three of homonymy have been recorded for samples harvested from different countries. Cultivars with identical genotypes were mostly detected between neighboring countries. No clear differentiation between countries was detected although several specific alleles were detected. The integration of the obtained genetic data with ampelographic ones is very important for accurate identification of the SEE cultivars and provides a significant tool in cultivar preservation and utilization.

Self-potential anomalies in some Italian volcanic areas

The study of Self-Potential (SP) space and time variations in volcanic areas may provide useful information on both the geometrical structure of the volcanic apparatuses and the dynamical behaviour of the feeding and uprising systems. In this paper, the results obtained on the islands of Vulcano (Eolian arc) and Ponza (Pontine archipelago) and on the Mt. Somma-Vesuvius complex are shown. On the island of Vulcano and on the Mt. Somma-Vesuvius apparatus areal SP surveys were performed with the aim of evidencing anomalies closely associated to the zones of major volcanic activity. On the island of Vulcano a profile across the fumaroles along the crater rim of the Fossa Cone was also carried out in order to have a direct relationship between fumarolic fracture migration and flow rate and SP anomaly space and time variations. The areal survey on the island of Ponza, which is considered an inactive area, is assumed as a reference test with which to compare the amplitude and pattern of the anomalies in the active areas. A tentative interpretation of the SP anomalies in volcanic areas is suggested in terms of electrokinetic phenomena, related to the movement of fluids of both volcanic and non-volcanic origin
