“…The data obtained in our investigations Ekhvaia et al, , 2011Asanidze et al, 2011) indicate importance of CWR species in Georgia as many of them represent direct ancestors of local cultivars. The fact that wild grape shows high genetic relation to local varieties of grape indicates that winemaking represents an ancient culture in Georgia, which is expressed even in religious rituals of the nation.…”

“…Relationships between wild P. caucasica and local cultivars are mirrored by a high morphological variability of leaf and fruit forms. This idea was for the first time confirmed by statistical methods of taxonomic identification and relationships among taxa in our study (Asanidze et al, 2011). We decided to conduct comparative morphometric study of cultivars recently occurred in Georgia and reveal their relationship to local wild pear species.…”

“…We have studied domestication of wild grapevine (Vitis vinifera subsp. sylvestris) and wild pear (Pyrus caucasica) using morphometric and systematic molecular methods Asanidze et al, 2011) confirming genetic relationships between wild populations and local cultivars of grape and pear. However, complete evaluation of diversity of Georgian local cultivars and crop wild relatives (CWR) has not yet been complete.…”

“…Several studies have been carried out in pear to assess the genetic diversity using a combination of morphological and molecular tools. This includes morphological evaluation (Asanidze et al 2011;Santiago-Pereira et al 2012;Trivedi et al 2012;Bhat et al 2013;Said et al 2013); RFLPs (Iketani et al 1998;Katayama and Uematsu 2003), RAPD (Kim et al 2005) and AFLP (Dolatowski et al 2004;Bao et al 2008). Recently, SSR markers have been effectively used in Pyrus species (Yao et al 2010;Baraket et al 2011;Sehic et al 2012;Cao et al 2012;Erfani et al 2012;Akcay et al 2014).…”

Genetic diversity and phylogenetic relationships among 48 pear accessions belonging to six species were determined using 23 morphological traits and 20 simple sequence repeat (SSR) primers. To assess the genetic diversity, data on morphological (both quantitative and qualitative) traits were recorded during 2010-2012 using standard pear descriptors. It was observed that the traits ratio of fruit length to diameter, persistency of calyx on mature fruits and fruit surface and pulp texture were important in detecting variation across pear species. At molecular level, 20 SSR primers amplified 190 polymorphic alleles with an average of 9.5 alleles per primer. Size of amplified alleles ranged from 85 to 450 bp. Mean polymorphic information content (PIC) was 0.80 showing high level of SSR polymorphism. Bayesian model-based STRUCTURE analysis assigned genotypes into five clusters and also showed the extent of admixture within individuals. Genotypes belonging to Pyrus pyrifolia were clustered into two different clusters indicating broad genetic base for this species while Pyrus communis genotypes appeared to have conserved genetic makeup. Dendrogram-based on Jaccard's similarity coefficient and neighbor-joining tree showed two major groups of Asiatic (P. pyrifolia, Pyrus pashia, Pyrus serotina and Pyrus jacquemontiana) and European (P. communis) pears. However, accessions belonging to P. pyrifolia were further divided into subgroups. Cluster analysis based on morphological traits was in agreement with the dendrogram and structure clusters obtained with SSR data. The Mantel matrix correspondence test was used to further compare the molecular and morphological similarity matrices and positive correlation coefficient (r=0.164; P=0.001) was observed. Results of this study present important information about genetic structure of Indian pear accessions which can contribute significantly to future breeding and improvement programmes in this species.

Nowadays, fig (Ficus carica L.) fruits are consumed either fresh or dried and used for jam or spirit beverage production. Morphological and pomological diversity of 49 wild edible fig accessions sampled was evaluated. Analysis of variance revealed significant differences among the wild accessions studied using the morphological data recorded. Ripening time ranged from late July to mid-August. Fruit skin ground color showed high variability, including cream-purple (4 accessions), purple-yellow (8), light purple (7), purple (15), dark purple (5), purple-cream (3), and cream (7). The range of fruit-related traits was as follows:
