“…A highly significant negative correlation was found between the oleic and linoleic acids. As previous reported in other crops such as almond under different environmental conditions (Kodad and Socias i Company 2006), this negative correlation may be explained by the enzymatic activity of desaturase which converts oleic acid to linoleic (Garcia et al 1992). Furthermore, correlation coefficients greater than 0.71 or smaller than -0.71 have been suggested to be biologically meaningful (Skinner et al 1999) showing that this correlation is not influenced by climatic and environmental conditions and it is genotype-dependent (Kodad et al 2011).…”

In the frame of SAFENUT AGRI GEN RES Action, which was a European strategy for the recovery, characterization and conservation of genetic resources, the fatty acids and the tocopherol profiles of a set of 75 hazelnut accessions were analyzed. The aim of this study was to assess the genetic differences among the European germplasm, contributing to the definition of nut quality in traditional European areas of cultivation. Significant differences were found between accessions for oil amount and contents of most fatty acids. As expected, monounsaturated fatty acids made up the largest portion (mean 80.85 %) followed by polyunsaturated fatty acids (10.70 %). The saturated ones were the minor components and accounted for only 8.43 % of the total fatty acids. On the basis of Student's test, significant differences between the 2 years of harvest were found for fatty acid content, except for linoleic acid, the ratio of polyunsaturated, a-tocopherol and the stability index. When the oil content was studied in cultivars from the same site of cultivation, the mean values of the genetic pools from central Italy (60.8 %), Slovenia (59.3 %) and Portugal (58.2 %) showed highest values than those of cultivars grown in Greece (56.8 %), Spain (55.9 %) and France (51.5 %). A chemometric approach based on principal component and clustering analyses was developed to identify the most interesting cultivars for breeding programs.

“…As regards minor components present in almond oils, most of scientific studies have primarily focused on tocopherol content and its effect on oil preservation (Kodad, Socias i Company, Prats, & López-Ortiz, 2006;López-Ortiz, Prats-Moya, & BerenguerNavarro, 2006;López-Ortiz et al, 2008;Zacheo, Cappello, Gallo, Santino, & Cappello, 2000). Almonds are considered one of the richest food sources of a-Toc (Chen, Lapsley, & Blumberg, 2006) -which is a well-known natural antioxidant -and its concentration was proposed as a selection criterion in almond breeding (Kodad et al, 2006).…”

“…Besides giving the morphological and agronomical description of these promising almond genetic resources (Carra de Tolosa & Herrera, 2006), studies should also define their nutritional value. A lot of studies have been carried out on the characterisation of different almond cultivars and criteria for almond kernel quality evaluation, and some works have focused on fatty acid profile, triacylglycerol and tocopherol composition as discriminant parameters in order to differentiate almond genotypes (Askin et al, 2007;García-López, Grané-Teruel, Berenguer-Navarro, García-García, & Martín-Carratalá, 1996;Grane-Teruel, Prats-Moya, Berenguer-Navarro, & Martín-Carratala, 2001;Kodad et al, 2006;López-Ortiz et al, 2008;Martín-Carratalá et al, 1999).…”

During the period 2007-2010, the European Project SAFENUT: "Safeguard of almond and hazelnut genetic resources from traditional uses to modern agroindustrial opportunities", has been carried out in Europe, by researchers from six European countries and the participation of 11 different partners. Several aspects referred to Corylus avellana L., were tackled: the survey of local national and European hazelnut collections and on farm recovery of "ecotypes"; the evaluation of plant material (morphological, biochemical and molecular assessment); the creation of a hazelnut core collection; the analysis of ecological, economic and socio-cultural aspects related to sustainable production and traditional knowledge; and, finally, the establishment of the SAFENUT website and database. With the aim to harmonise the morphological evaluations, specific descriptors were elaborated for the characterization of genetic materials, both in the permanent collection and in new selections. 306 hazelnut accessions were analyzed at 10 SSR loci in order to verify the genetic authenticity. The main cultivars of each country were evaluated for fatty acids, tocopherols, phenolic compounds, mineral and protein contents. In the light of the above, the multivariate analysis of the entire data allowed the creation of the hazelnut core collection. The recovery of traditional knowledge was undertaken by different activities: questionnaires were elaborated following the interviews of students and their parents in all partner countries; a survey on the festivals related to this species was carried out and a publication was released. Furthermore, 63 filled questionnaires addressed to farmers offered the opportunity to compare problems, technical practices and biodiversity at the European level. Finally, the SAFENUT Database, a web interface available at the address: hppt://www.safenut.net, has been set up in order to provide users driven on-line search-queries, across multi-trait data based on germplasm evaluation. The European SAFENUT experience has allowed the realization of an efficient working group, able to draw out the authentic significance of genetic resources, not only working on the unique genetic background offered by genetic resources, but also on the cultural meaning that they represent. INTRODUCTIONAn exhaustive study of the preservation and utilization of European hazelnut (Corylus avellana L.) genetic resources were carried out during three years (2007)(2008)(2009)(2010)
