Toward the valorization of olive (Olea europaea var. europaea L.) biodiversity: horticultural performance of seven Sicilian cultivars in a hedgerow p…
2019
Abstract An intense survey of the Sicilian’s olive growing areas for autochthonous germplasm, mainly represented by centennials olive trees (Olea europaea var. europaea L.) apparently older then III centuries, started at the beginning of the 1980s and resulted in the selection of more than 150 cultivars and accessions. This germplasm was propagated in a nursery, by grafting onto seedlings of Olea europaea L., and planted in an experimental orchard, in an olive district located in the South-west of the Island, where they were evaluated for over 30 years and selected for their early bearing, high and constant productivity, as well as high oil content of the fruits and excellent chemical (olei…
Species diversity of larval parasitoids of the European grapevine moth (Lobesia botrana, Lepidoptera: Tortricidae): the influence of region and culti…
2010
7 pages; International audience; The European grapevine moth, Lobesia botrana (Denis & Schiffermüller, 1775) (Lepidoptera: Tortricidae) is a major pest of grapevines responsible for great economic losses and frequent insecticide applications. Nevertheless, the use of parasitoids as potential biological control agents has received very little attention. In this study, we present results from a survey on parasitoid species collected from French and Swiss vineyards over a period of 2 years. Over 2000 larvae of L. botrana were collected from six grape cultivars out of which a total of 118 parasitoids emerged. Ten species were identified. Exochus notatus (Holmgren, 1858) (Hymenoptera: Ichneumoni…
Aromatic and proteomic analyses corroborate the distinction between Mediterranean landraces and modern varieties of durum wheat
2016
AbstractIn this paper volatile organic compounds (VOCs) from durum wheat cultivars and landraces were analyzed using PTR-TOF-MS. The aim was to characterize the VOC’s profile of the wholemeal flour and of the kernel to find out if any VOCs were specific to varieties and sample matrices. The VOC data is accompanied by SDS-PAGE analyses of the storage proteins (gliadins and glutenins). Statistical analyses was carried out both on the signals obtained by MS and on the protein profiles. The difference between the VOC profile of two cultivars or two preparations of the same sample - matrices, in this case kernel vs wholemeal flour - can be very subtle; the high resolution of PTR-TOF-MS - down to…

First report of grapevine fleck virus in vineyards of Bosnia and Herzegovina
2020
Grapevine is one of the most important fruit crops in Bosnia and Herzegovina with an annual production of around 40 thousand tons in 2018 (FAOSTAT, http://www.fao.org/ faostat/en/#data/QC). Production of grapevine in the country is mainly concentrated in vineyards in the Lištica and Mostar regions of Herzegovina with the two predominant autochthonous cultivars ‘Žilavka’ and ‘Blatina’. Grapevine fleck virus (GFkV) from the genus Maculavirus in the family Tymoviridae is a phloem limited virus with a positive-sense single-stranded RNA genome (Dreher et al. 2012). GFkV is associated with fleck disease of Vitis spp. In order to investigate the current status of GFkV in Bosnia and Herzegovina, 80…
Genetic analysis of Citrus aurantium L. (Rutaceae) cultivars by ISSR molecular markers
2011
Eight cultivars of Citrus aurantium L., showing peculiar morphological traits of the fruits and leaves, were analyzed genetically. Inter simple sequence repeat (ISSR) was chosen as molecular markers because they represent a highly efficient system for investigating variability at intraspecific level. The particular morphological traits were discussed, the genetic identity and distance matrix based on Nei index was calculated, and the unweighted pair group method with arithmetic mean (UPGMA) dendrogram was generated. A total of 53 clearly distinguished DNA bands were considered for the ISSR analysis of which 24 were polymorphic. A basic C. aurantium fingerprinting pattern was obtained. The I…
Centennial olive trees as a reservoir of genetic diversity
2011
†Background and Aims Genetic characterization and phylogenetic analysis of the oldest trees could be a powerful tool both for germplasm collection and for understanding the earliest origins of clonally propagated fruit crops. The olive tree (Olea europaea L.) is a suitable model to study the origin of cultivars due to its long lifespan, resulting in the existence of both centennial and millennial trees across the Mediterranean Basin. †Methods The genetic identity and diversity as well as the phylogenetic relationships among the oldest wild and cultivated olives of southern Spain were evaluated by analysing simple sequence repeat markers. Samples from both the canopy and the roots of each tr…
Almond Germplasm in Bostanlyk Area (Uzbekistan): Preservation and Exploitation
2014
Almond germplasm has been studied throughout the world with high diversity identified in the Mediterranean Basin. Each production region is based on specific types of cultivars, frequently without a real commercial strategy. For this reason we still have a wide range of particularly interesting almond germplasm, especially for genetic improvement. In some parts of the world, local germplasm is still interesting for a restricted almond industry, usually related to a local or internal consumption. In this paper we provide details about the almond industry in the traditional area of Bostanlyk, Uzbekistan. Since 2007 a specific approach to evaluate the local germplasm has been applied; the most…
A comparative analysis of genetic variation in rootstocks and scions of old olive trees – a window into the history of olive cultivation practices an…
2014
Background Past clonal propagation of olive trees is intimately linked to grafting. However, evidence on grafting in ancient trees is scarce, and not much is known about the source of plant material used for rootstocks. Here, the Simple Sequence Repeat (SSR) marker technique was used to study genetic diversity of rootstocks and scions in ancient olive trees from the Levant and its implications for past cultivation of olives. Leaf samples were collected from tree canopies (scions) and shoots growing from the trunk base (suckers). A total of 310 trees were sampled in 32 groves and analyzed with 14 SSR markers. Results In 82.7% of the trees in which both scion and suckers could be genotyped, t…
Analysis of aroma compounds of nine autochthonous and non-autochthonous loquat cultivars grown in Sicily
2021
Loquat cultivation in Sicily is mainly based on nonnative cultivars and local ecotypes characterized by high nutraceutical value and appreciable physicochemical characteristics. Increased interest in commercial loquat production has increased the intention to provide premium quality loquat cultivars that include volatile substances capable of conditioning the sensorial properties and, therefore, the acceptability of fruits by consumers. This study determined the content of volatile compounds in nonnative and local loquat fruits grown in Sicily. Analyses were performed on five international cultivars and four local cultivars.
