cv. 'Garrone Rosso' and 'Marrone di Castel del Rio' are two of the most prized varieties in Italy due to their valuable and healthy nuts used for fresh consumption and in the confectionery industry. Despite the growing demand for chestnuts, there are constraints regarding plant propagation that hamper the renewal and new planting of orchards in different areas.

Eight Sicilian cultivars of hazelnut ( L.), namely-Curcia, Nociara Collica, Panottara Collica, Panottara Galati Grande, Parrinara, Panottara Baratta Piccola, Enzo, and Rossa Galvagno, registered into the Italian Cultivar Register of fruit tree species in 2017 were selected from Nebrodi area and established . The aim of the work was to carry out the sanitation of the cultivars and get virus-free plants from the most important viral pathogen threat, the .

The domestication and spreading of grapevine as well as the gene flow history had been described in many studies. We used a high-quality 7k SNP dataset of 1,038 Eurasian grape varieties with unique profiles to assess the population genetic diversity, structure, and relatedness, and to infer the most likely migration events. Comparisons of putative scenarios of gene flow throughout Europe from Caucasus helped to fit the more reliable migration routes around the Mediterranean Basin.

Article Synopsis
  • Grapevine reproductive development is crucial for determining yield and wine quality, as it influences factors like seedlessness and berry size, which are affected by seasonal climate variations.
  • Eight distinct grapevine variants with different seed characteristics were identified, showing identical genotypes, highlighting the complexity of reproductive traits.
  • The study highlights the importance of genetic and phenotypic analysis in understanding seedlessness and reproductive processes, revealing unexpected findings about fruit development without pollen and the presence of unreduced gametes in certain variants.

Northwestern Italy is a wine region of the world with the highest of reputations, where top quality wines of remarkable economic value are produced from traditional, long-cultivated varieties. Kinship analyses were performed using 32 microsatellite loci and more than 10 K single-nucleotide polymorphism markers on 227 traditional grapes mostly from Northwestern Italy-including those that have been neglected or are threatened. This was done to better understand the genetic grapevine origins and history of this reputable wine producing area, thus enhancing its cultural value and the marketing appeal of its wines.
