“…Indeed, they were grouped in to distinguished subclusters. This is in line with the study of Albertini et al (2011). Their results suggested that climatic conditions responsible for mutation in single population along with both sexual and vegetative propagation played a role in the evolution of olive.…”

Abstract. Wild (O. cuspidata) and cultivated olive (O. europaea) grow in northern regions of Pakistan including Azad Jammu and Kashmir are expected to have considerable inter and intra-species genetic variability due to adaptation to the various environmental conditions. The genetic relationship was investigated in wild and cultivated olive populations growing in Azad Jammu and Kashmir by using four primer combinations during Amplified Fragment Length Polymorphism (AFLP) analysis. Genetic relationships were displayed in a dendrogram based on Unweighted Pair Group Method (UPGMA) and Principal Component Analysis (PCA). Four clusters were clearly separating wild and cultivated olive populations from each other indicated that the Olea cuspidata (wild) which is an Afro-Asiatic species found particularly in this region and Olea europaea (cultivated) were divergent. The insightful difference between wild and cultivated populations and the close relationship among Olea europaea accessions had confirmed that the cultivated olive did not develop locally but were introduced from abroad, propagated by grafting on local wild olive. Moreover, analysis of cultivated olive showed that they are probably from same population with common ancestry.

“…Some clues from the membership value provide useful information regarding the genetic makeup of the 60 olive accessions evaluated in this study. Only 19 accessions showed a membership value lower than 0.8 (Table 5), and according to Albertini et al (2011), these accessions might be defined as mixed or crossbred.…”

“…The olive tree has a large number of commercial cultivars with different levels of self-incompatibility (Grati-Kamoun et al, 2006). The phenological and reproductive biology of this species has been the focus of several studies aimed at identifying self-compatible cultivars and assessing rates of self-sterility (Albertini et al, 2011). Most modern olive cultivars are believed to have been obtained from the crossing of wild plants followed by focused human selection (Cordeiro et al, 2008), resulting in the generation of hundreds of cultivars over a period of centuries.…”

ABSTRACT. Olive trees have been grown since the beginning of civilization, and the consumption of olives and olive products is increasing worldwide, due to their health benefits and organoleptic qualities. To meet the growing market for olives, commercial cultivation of this species is expanding from traditional areas to new regions. Although the Brazilian olive industry has just begun to be established, breeding programs are already developing cultivars that are more adapted to local conditions. We used 12 microsatellite markers to evaluate 60 olive accessions, including several cultivars that were developed in Brazil. The analyses identified 72 distinct alleles; the largest number of alleles per locus were at the markers Genetic diversity in olive germplasms GAPU 101 and GAPU 71B, which contained 10 and 9 alleles, respectively. The largest allelic diversity and polymorphic information contents were also found at the GAPU 101 and GAPU 71B markers, with values of 0.8399/0.8203 and 0.8117/0.7863, respectively. Additionally, the 12 microsatellite markers generated a cumulative identity probability of 1.51 x 10 -10 , indicating a high level of accuracy of accession identification. The set of markers that we used allowed the identification of 52 of the 60 olive genotypes, in addition to the recognition of several varietal synonyms. The components of a two-dimensional principal coordinate analysis explained 48.6% of the total genetic variation. The results obtained from the microsatellite markers showed a substantial degree of genetic diversity in the olive tree accessions used in Brazil.

“…In other woody species, AFLP and ISSR have also been used in analysis of genetic diversity in Citrus spp. (Fang and Roose 1997;Biswas et al 2011), Vitis vinifera L. (Moreno et al 1998;Ergül et al 2006) or Olea europea L. (Essadki et al 2006;Albertini et al 2011). In Portugal, the number of landraces has decreased in the last decades and the few ones actually identified have been poorly characterized.…”

Genetic relationship among wild, landraces and cultivars of hazelnut (Corylus avellana) from Portugal revealed through ISSR and AFLP markers

The genus Corylus, a member of the birch family Betulaceae, includes several species that are widely distributed throughout temperate regions of the Northern Hemisphere. This study assesses the genetic diversity in 26 international cultivars and 32 accessions of Corylus avellana L. from Portugal: 13 wild genotypes and 19 landraces. The genetic relationships among the 58 hazelnuts (Corylus avellana L.) were analyzed using inter simple sequence repeat (ISSR) and amplified fragment length polymorphism (AFLP) markers. Eighteen ISSR primers and seven AFLP primer pairs generated a total of 570 unambiguous and repeatable bands, respectively, from which 541 (95.03 %) were polymorphic for both markers. Genetic similarity index values ranged from 0.239 for wild types and cultivars to 0.143 for landraces and wild types. The genetic relationships were presented as a Neighbor-Joining method dendrogram and a two-dimensional principal coordinate analysis (PCoA) plot. The Neighbor-Joining dendrogram showed three main clusters, and the PCoA analysis has shown to be congruent with the hierarchical analysis. Bayesian analysis clustered all individuals into three groups showing a good separation among wild genotypes, landraces and cultivars. The genetic diversity found on wild genotypes and Portuguese landraces may provide relevant information for the diversity conservation and it will be useful in breeding programs and to identify local selections for preservation.
