    The Effects of the Polinator Grape Cultivar Kalecik Karasi on the Progeny Fertility of Some Grape Cultivars
    (Ankara Univ, Fac Agr, 2007) Karatas, Huseyin; Agaoglu, Y. Sabit
    In this research, germination rate of seeds and fruit set of F1 hybrids obtained by hybridization studies conducted on Italia, Muscat Hamburg, Papaz karasi, Narince and Riesling grape cultivars were pollinated with Kalecik karasi grape cultivar, was investigated. Among cultivars which were pollunated with Kalecik karasi grape cultivar, the highest fruit set ratio was obtained from Muscat Hamburg grape cultivar (38.0%) however the lowest fruit set ratio, was obtained from Riesling grape cultivar (18.0%). The highest germination rates of seeds achieved from Italia grape cultivar (43.3%). The lowest germination rates of seeds achieved from Papaz karasi (17.0%) cultivar. When seedling set ratios investigated among F, off springs that were obtained by hybridization studies, the highest seedling set ratios were obtained from Riesling (85.0%). However Ata sarisi grape cultivar had the lowest seedling set ratio (50.1%). Approximately, 232 F1 hybrid progenies were producted as a result of hybridizations.

    Elemental Composition of Red Wines in Southeast Turkey
    (Czech Academy Agricultural Sciences, 2015) Karatas, Dilek Degirmenci; Aydin, Firat; Aydin, Isil; Karatas, Huseyin
    Mineral profiles of wines and soil extracts were analysed in the five most popular international wines (Cabernet Sauvignon, Syrah, Merlot, Cot, and Tannat) and national Bogazkere, which is one of the highest-quality grapevine varieties grown in Turkey. We carried out study to establish the mineral and metal concentrations in wines from Southeast Anatolia of Turkey. The ICP-OES method was used for accurate determination of concentrations of 12 elements including Ca, Cd, Co, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, and Zn. The high levels of iron, potassium, sodium, and calcium were observed in the wine samples analysed. Major elements were also abundantly found in the soil samples. Minor element contents of wine samples were compatible with results other researches. The amount of metal content in wine is an important issue. A remarkable finding of the study was that heavy metals like Pb (found below acceptable limits only in three samples), Co, and Cd were not detected. The results obtained did not exceed the maximum acceptable limits established by the Office International de la Vigne et du Vin. Our results showed that the mineral compositions of wine and soils were interrelated. The analysis of the soil samples taken from the vineyard locations showed similar results for highest composition of major minerals. The characteristics of the wines produced in the Southeast Region of Turkey were analysed for the first time.

    GENETIC CHARACTERIZATION OF GRAPEVINE GERMPLASM (VITIS VINIFERA L.) BY SSR (SIMPLE SEQUENCE REPEATS) IN SANLIURFA PROVINCE, SOUTHEAST TURKEY
    (Parlar Scientific Publications (P S P), 2019) Karatas, Huseyin; Karaagac, Eda; Karatas, Dilek; Agaoglu, Sabit
    In this study, grape cultivars growing in Sanliurfa were analyzed and compared using molecular markers. The analysis was performed with 50 genotypes using 7 microsatellite markers. Total number of alleles per locus ranged from 7 (VrZAG62 and VrZAG79) to 9 (VVS2), with a mean number of 7.9 alleles per locus. The expected and observed heterozygosity were 0.7509 and 0.6958, respectively. Clustering analysis was conducted using the UPGMA method (Unweighted Pair-Group Method using Arithmetic means). The analysis of similarity index revealed 6 distinct groups, each of which included several subgroups: Group I included 8, Group II included 4, Group III included 11, Group IV included 9, Group V included 10, and Group VI included 8 subgroups. The two reference genotypes, Cabernet Sauvignon and Merlot, were classified into a separate subgroup within Group V. In conclusion, 17 synonyms and 8 homonyms were identified for the genotypes analyzed in our study.

    Genetic diversity of wild and cultivated grapevine accessions from southeast Turkey
    (Bmc, 2014) Karatas, Dilek Degirmenci; Karatas, Huseyin; Laucou, Valerie; Sarikamis, Golge; Riahi, Leila; Bacilieri, Roberto; This, Patrice
    Wild grapevine genetic diversity in southeast Turkey has not been documented to date. In the present work, in order to clarify the relationships between wild and cultivated grape accessions from southeastern Turkey, 22 nuclear and three chloroplast microsatellite loci were used on 21 wild grapevine Vitis vinifera L. ssp. sylvestris (Gmelin) and 13 cultivated grapevine Vitis vinifera ssp. sativa accessions. The number of alleles per SSR locus ranged from 4 (VVIn16) to 20 (VVIv67) and the mean allele number per locus was 10.09. Expected locus heterozygosity ranged from 0.586 (locus VVIb01) to 0.898 (locus (VVIv67)). The three cpSSR molecular markers presented variation in size both in cultivars and in wild Turkish accessions. Two size variants were detected for cpSSR3 (106 and 107 bp) for cpSSR5 (104 and 105 bp), and for cpSSR10 (115 and 116 bp). The six alleles in wild grapevines fell into three haplotypes B, C and D. A genetic structure according to accessions taxonomic status (wild or cultivated) was revealed by UPGMA analysis. This highlighted a clear separation between domesticated and wild accessions in Turkish germplasm. The results pointed out the need to further collect and characterize this wild and cultivated grapevine germplasm.

    Morphological Characterization of Endangered Wild Grapevine Vitis vinifera ssp silvestris in Eastern Turkey
    (Amer Pomological Soc, 2014) Karatas, Diler Degirmenci; Karatas, Huseyin; Garcia-Munoz, Sonia
    Vitis vinifera L. ssp. silvestris (Gmelin) Hegi selections from three regions in Eastern Anatolia (Turkey) were morphologically characterized in this study. The wild populations were typically located in hilly areas and on the sides of valleys. Samples from six populations including 26 individual, distinctive Vitis vinifera ssp. silvestris vines were observed in 2010 by ampelographic evaluation using 35 OIV descriptors (OIV, 1983), modified by Project GENRES 081 (2001). These descriptors from the OIV list include young shoot, shoot, mature leaf, woody shoot, flower sexual organ and berry descriptors. Three hermaphroditic individuals were found, highlighting the differences between the wild and cultivated grapevine. The plants were grouped into four groups, using a cluster dendrogram, that generally matched the original location of each of the individual vines. Morphological characterization of wild grapevine Kits vinifera ssp. silvestris in eastern Turkey is the first step in preserving this valuable genetic resource.
