Genetic analysis of central Anatolian grapevine (Vitis vinifera L.) germplasm by simple sequence repeats

The Anatolian peninsula otherwise known as Asia Minor is considered one of the centers that shaped grape (Vitis spp.) evolution and domestication. This region with diverse ecological conditions also has a long history of viticulture and growing grapes has been a part of the local culture since very old times. However, very little information is available on genetic analysis of Anatolian grape germplasm. This study reports on genetic analyses of 88 grapevine cultivars from Central Anatolia using 17 microsatellite (SSR) loci. The average number of alleles per locus was 9.18, ranging from 5 to 15. The highest heterozygosity rate was obtained for the SSR loci “VVS2” and “VMC2H4.” Genetic distances between populations ranged from 0.056 to 0.207 and two cases of identical, seven cases of homonymous, and nine cases of synonymous grape cultivar groups were identified. Based on comparisons with international Vitis databases, it has been determined that “Moldova-Coarna Neagra” cultivar is synonymous with some Anatolian cultivars. In addition, investigation of the genetic diversity of 20 genotypes of Anatolian wild germplasm revealed a higher level of genetic diversity in wild populations than in cultivated ones at the studied microsatellite loci. The results reported here should not only contribute towards better management of the grape germplasm of the region but also provide new insights into grape domestication

Genetic characterisation and population structure analysis of Anatolian figs ( Ficus carica

© 2021 Ali Ergül et al., published by Sciendo 2021.The common fig (Ficus carica L.) is a tree species and is one of the oldest fruit trees cultivated in Turkey. The Western Anatolian region of Turkey produces nearly a quarter of the total dried fig production of the world. This region also harbours a rich fig germplasm. However, so far this germplasm has remained largely uncharacterised. In this study, using 14 simple sequence repeat (SSR) primer pairs, we analysed a total of 310 fig accessions from six different regions of Anatolia. In structure analyses, Western Anatolian accessions formed a group, which was correlated with their geographical distribution. In addition, 7 identical, 36 synonymous, and 22 homonymous fig accessions were identified. In multilocus lineages (MLLs) analysis a total of 54 accessions were matched to different accessions as clone assignment. The results will facilitate future germplasm management and breeding efforts in this economically important tree species by identifying genetic diversity, genetic relations and characterising the structure of studied populations and accessions
