A prioritised inventory of crop wild relatives and wild harvested plants of Tunisia
2022
AbstractAn inventory of crop wild relatives (CWR) and wild harvested plants (WHP) occurring in Tunisia, based on the integration of the last available floristic checklists, is presented. The taxa were prioritised according to economic value of the related crop, potential for crop improvement, threat status, endemism, inclusion in the ITPGRFA (Annex I) and average annual contributions to dietary energy (kilocalories) per capita per day by applying a scoring system based on 4 priority levels. Of a total of 2912 taxa belonging to the Tunisian Flora, 2504 CWR and/or WHP (86% of the total), from 143 families and 686 genera, were identified, 2445 of which are CWR and 847 are WHP. In detail, 1654 …
Identification of (In)Compatible S-genotypes and Molecular Characterisation of Italian Sweet Cherry Cultivars.
2017
Italy is the first sweet cherry producer in Europe. Its rich germplasm of local varieties has not been fully characterised or exploited in breeding programmes. Sweet cherry is a self-incompatible species; this trait is controlled by a gametophytically expressed multi-allelic (S) locus. The knowledge of sweet cherry S-alleles and cross-incompatibility groups is important for growers and breeders for choosing appropriate pollinators in the orchard and planning crosses. In this work, we analysed 94 sweet cherry cultivars native of large part of the Italian regions where cherry is grown. The microsatellite primer pair set and the reference cultivars agreed for cherry by the Prunus Working Group…
A study of thyme germplasm in Sicily
2009
hyme is characteristic of the Mediterranean and is of interest for its multifunctional nature. It is widely used in seasoning and flavouring, in herbal products and cosmetics. The versatility of this species means it is also useful in the protection of areas prone to erosion or an ornamental plant when designing low-maintenance gardens. Thyme germplasm constitutes a large part of the wild flora in Sicily and is a potentially useful source of genetic variability. On the basis of this, in the two-year period from 2004-2005, research was carried out on wild thyme accessions. These were used to evaluate both its productivity and individual biotypes with the functional characteristics most sough…
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’,…
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…
Assessment of genetic diversity and relatedness in the Latvian potato genetic resources collection by DArT genotyping
2015
Potato (Solanum tuberosumL.) has been cultivated in Latvia since the 17th century, and formal breeding programmes have been established since the start of the 20th century. The Latvian potato genetic resource collection consists of 83 accessions of Latvian origin, including landraces, old cultivars released starting from the 1930's, modern cultivars and breeding material. These are maintained in field andin vitrocollections. Pedigree information about the potato cultivars is often limited, and the use of hybrids of local cultivars as parents is common in the Latvian potato breeding programme. Ninety-four Latvian potato varieties and breeding lines and some commonly used foreign accessions w…
RESTORATION OF LATVIAN ALFALFA (Medicago sativa) GENETIC RESOURCES PERSPECTIVE FOR BREEDING
2015
We have carried out restoring of some Latvian alfalfa genetic resources from seeds of accessions that did not germinate in soil at all. Two of them were repatriated from the N. Vavilov All-Russian Institute of Plant Industry (multiplied more than 40 years ago) and three from the Research Institute of Agriculture (Latvia) (multiplied 15-20 years ago). For germination of old seeds we used early elaborated in vitro culture conditions. Germination rate ranged 2-60%, depending from the genotype and seeds storage conditions. Plantlets with well developed roots and 2-3 leaves were planted in the substrate in small pots and grown in a greenhouse about a month, then replanted in the soil in field co…
PRODUCTIVE, COMMERCIAL AND QUALITATIVE CHARACTERIZATION OF SICILIAN LANDRACE TOMATO.
2012
This paper shows the results obtained in 2007 of a study carried out at the Sparacia experimental farm (Cammarata AG, 37°37’N, 13°42’E) aimed at identifying and evaluating 26 populations of “long-life tomato” collected from the Province of Palermo, Agrigento and Trapani. The farm, which belongs to the Sicilian Agricultural Development Agency (E.S.A), is located in a sub-arid area with average rainfall levels of approx. 500 mm and average min/max temperatures of 9 and 21°C. The soil is characterised by level land, deep soil with sandy clay texture and subalkaline soil pH classified as Eutric Vertisols, WRB (FAO-ISRIC-ISSS, 1998). The planting tomato crop was carried out according to traditio…

Plant genetic resources and traditional knowledge on medicinal use of wild shrub and herbaceous plant species in the Etna Regional Park (Eastern Sici…
2014
Ethnopharmacological relevance: This paper illustrates the results of a study carried out in the Etna Regional Park (Eastern Sicily, Italy) concerning the traditional knowledge on medicinal use of wild plant species. It specifies contains the results of a quantitative analysis carried out for the first time. A total of 71 wild species are used for medicinal purposes. Two species, Astracantha sicula (Biv.) Greuter and Trifolium phleoides Willd., are little known as medicinal in the Mediterranean area. Aim of the study: The main aim of the study was to understand to what extent current knowledge on the medicinal use of plants is still an element of the culture within the elderly population of…
