“…Hegi, which we did not analysed. This is a highly diverse taxon that comprises morphologically and genetically distinct geographic populations and its taxonomic status remains uncertain (Ekhvaia and Akhalkatsi 2010;Myles et al 2011;Zecca et al 2012).…”

Chloroplast markers are powerful tools for research into relationships among grapevine (Vitis vinifera L. subsp. vinifera) cultivars. However, the high number of regions common to the chloroplast and mitochondrion genomes described in grapevine could interfere with correct phylogeny reconstruction. In this study, we established a unique chloroplast marker (UCM) set and investigated the chloroplast haplotype diversity of 17 grapevine cultivars and seven Asian Vitis species. Sequencing of four UCMs revealed four haplotype groups in grapevine based on three nucleotide substitutions, three simple sequence repeats, and one 54 nucleotide (nt) deletion in the trnC-petN region. The constructed molecular-variance parsimony and statistical parsimony networks indicated that two independent maternal lineages of grapevine cultivars originated from a core group of Asian Vitis species. The presence and absence of a newly discovered 54 nt deletion corresponded to the two maternal lineages: deletion (D) and non-deletion (ND) lineages. The D lineage consisted of three haplotypes, represented by 'Furmint', 'Gouais blanc', and 'Sauvignon blanc'. Ancient noble cultivars, such as 'Pinot noir', 'Riesling', and 'Afus ali', belong to a single haplotype group (ND) in which the deletion was absent. Our results provide compelling evidence for the dual maternal origin of grapevine, and suggest the occurrence of an ancient hybridization event.

“…The observations were recorded from ten randomly selected plants from each accession in each replication for thirteen quantitative characters viz., Plant Height (CM), Number of leaves per plant, Leaf Length (CM), Leaf width (CM), Chlorophyll Content (CCI), Neck Thickness (CM), Total Soluble Solids (%), Dry Matter (%), Polar Diameter (CM), Equatorial Diameter (CM), Bulb Shape Index, Average Bulb Weight (g) and Bulb Yield (Kg/Plot) and four qualitative traits viz., Colour of Foliage, Degree of Leaf Waxiness, Uniformity of Bulb Shape, Colour of Bulb Skin. All four qualitative traits were interpreted as per the method of Ekhvaia and Akhalkatsi (2010). The traits were observed as per International Plant Genetic Resources Institute (IPGRI) plant descriptors for Allium species.…”

In the present work, the variability, interrelationship, and divergence pattern of twenty six accessions of onion at high altitude were studied based on quantitative and qualitative traits. Multivariate analysis was used to classify the twenty six onion accessions. Cluster I contained two genotypes, cluster II contained ten genotypes, cluster III contained two and cluster IV contained twelve genotypes. The highest inter-cluster distance was observed between I and IV, and the lowest between I and II. The maximum intra-cluster distance was observed in Cluster II and the minimum in cluster III. The intra-cluster distance in all the four clusters was relatively low, indicating that genotypes within the same cluster were closely related. Based on cluster means, cluster 1 is the best in terms of number of leaves and neck thickness, cluster II best in terms of leaf width, Double/deformed bulb, Polar diameter, equatorial diameter, average bulb weight and bulb yield kg/plot, cluster III is the best in terms of days to maturity, TSS and dry matter content and cluster IV which is best in terms of plant height, leaf length and chlorophyll content. Considering cluster distance and cluster mean, the intra cluster distance revealed that the genotypes from the cluster II and genotypes from the cluster IV may be selected as parents for future breeding program. It was found that, PCA extracted three PCs and contributed 95.61 % of the variation out of which PC1 accounted 77.52 % variability, PC2 for 10.72 % and PC3 7.38 % variability of the variance among 26 accessions. The greater part of the variance was accounted for by other traits such as average bulb weight, bulb yield, leaf length, equatorial diameter and TSS. The high diversity found in the accessions shows great potential for improving qualitative as well as quantitative traits in onion.

“…There are ample evidences that the main land of Iran has been one of centres of origins for grape (Vitis vinifera L.), where wild clones still grow in forest areas Ekhvaia and Akhalkatsi 2010). The grapevine industry in Iran presently comprises over 286,000 ha with an annual production of 3,000,000 tons, playing a major role in the economy of this country (FAO 2012).…”
