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…

TWO YEARS OF STUDIES INTO NATIVE BERMUDAGRASS (CYNODON SPP.) GERMPLASM FROM SICILY (ITALY) FOR THE CONSTITUTION OF TURF CULTIVARS

2008

Bermudagrass (Cynodon spp.) is the most widely used warm season turf species in the world for sport, lawn and utility turfs. The species is widespread in Sicily (Italy) where it exhibits a large range of diverse morphological characteristics due to a long process of adaptation to varying climatic and soil conditions of the island. In order to exploit the bermudagrass genetic resources and establish a germplasm bank for use in various plant breeding programmes, bio-agronomic evaluation tests were carried out on the 40 Sicilian biotypes of Cynodon spp. from 2002 to 2004 at the experimental farm “Orleans”, University of Palermo. The accessions were compared to the standard cultivar ‘Savannah’,…

RECOVERY AND CHARACTERIZATION OF THE CHESTNUT GERMPLASM ON THE WESTERN SLOPES OF THE ASPROMONTE IN SOUTHERN CALABRIA

2010

For a considerable period of time chestnuts were a fundamental source of food and economy for the people in the Aspromonte area. After decades in which chestnut cultivation has been neglected as a result of depopulation in mountainous zones, the production capacity in this area has reduced resulting in an erosion of the native germplasm. A survey has been carried out to improve the knowledge about the chestnut germplasm present in this area and to evaluate its qualities with the objective of preserving native genetic resources, safeguarding them from genetic erosion phenomenon and individuating local genotypes of market value which could be used to promote a re-launch of local chestnut cult…

A quantitative analysis of wild herbaceous plant species for medicinal uses in four Regional Parks in Sicily (Italy)

2019

This paper illustrates the results of a study carried out in 4 regional Parks in Sicily (Italy) from 2009 to 2010. The study area covers a surface of 2076 km2, the 8% of the territory of Sicily, includes 90 towns and it is characterized by a high degree of plant biodiversity. The main aim of the study was to analyse the extent of the current knowledge on medicinal uses of wild shrub and herbaceous plants in the area, using quantitative indices. The information was obtained using semi-structured interview format performed on a sample of 802 people over the age of 60 who were considered experts in rural traditions. The results highlight that most of the species are used against general health…

Moscato Cerletti, a rediscovered aromatic cultivar with oenological potential in warm and dry areas

2021

Baron Antonio Mendola was devoted to the study of grapevine, applying ampelography and dabbling in crosses between cultivars in order to select new ones, of which Moscato Cerletti, obtained in 1869, was the most interesting. Grillo, one of the most important white cultivars in Sicily, was ascertained to be an offspring of Catarratto Comune and Zibibbo, the same parents which Mendola claimed he used to obtain Moscato Cerletti. Thus the hypothesis of synonymy between Moscato Cerletti and Grillo or the same parentage for both sets of parents needs to be verified.In the present study, historical documents were consulted and genetic analyses and ampelographic, agronomic and qualitative character…

The Sicilian peach (Prunus persica L. Batsch) germplasm: Evaluation of genetic diversity using SSRs

2006

The decrease in worldwide consumption of peaches due to the poor flavour quality of the fruit has increased the demand for new tasty cultivars. The availability of plant genetic resources is an important prerequisite for improving fruit quality by breeding. In Sicily there is a large collection of local cultivated peaches, whose production fills a niche in the local markets, but which is at risk of disappearing. Their characteristics include highly aromatic fruit and late ripening. Because of their important agronomic characteristics, the Department of Colture Arboree of Palermo University has collected the most interesting accessions to safeguard them and to use the indigenous resources in…

Identification of self(in)compatibility genotypes and microsatellite marker based fingerprinting of traditional italian sweet cherry accessions

2012

Italy is one of the main European sweet cherry producers and it has a rich germplasm, including many minor local varieties that have not been well studied or used in breeding programmes. Sweet cherry is self-incompatible, with few exceptions; its incompatibility is controlled by a multi-allelic S locus, which is gametophytically expressed. The knowledge of S-alleles and cross-incompatibility groups of sweet cherry genotypes and cultivars is important for growers and breeders. In this work we analysed 48 traditional sweet cherry varieties and cultivars, mainly from Calabria and Emilia Romagna regions, together with eight Sicilian cultivars and the standard set of reference genotypes proposed…

Recovery and genotyping ancient Sicilian monumental olive trees

2023

The long-lived and evergreen olive tree dominates the Mediterranean landscape, representing an agroecological and cultural symbol and a genetic heritage of inestimable value. Sicily, for historical, geographical, and cultural reasons, has a very rich and distinctive olive germplasm. In this work, a large survey was conducted to discover, collect, and characterize the genetic diversity of centennial monumental olive trees from historical sites, such as the Greek Temple Valley (Agrigento), ancient gardens, or farmland present in the western part of the island. Trees were chosen based on their height, trunk, stump size, and presumed age; particularly, only olive trees with an age estimated at …

Genetic variability of Chamaerops humilis (Arecaceae) throughout its native range highlights two species movement pathways from its area of origin

2023

AbstractThe European fan palm (Chamaerops humilis, Arecaceae) is the only native palm in continental Europe, providing ecosystem services that are hard to obtain from other species. However, its populations are declining in some areas due to anthropogenic effects including climate change. Knowledge of genetic variability among natural populations is needed to establish conservation plans, to prevent genetic contamination of native stands by cultivated germplasm and to exploit it as an ornamental species. However, information on the genetic similarities among C. humilis populations is scarce. The aims of this work were to study genetic structure in C. humilis using a set of specifically desi…
