Determination of Genetic Diversity Among Wild Grown Apples From Eastern Black Sea Region in Turkey Using ISSR and RAPDs Markers
Üst veriTüm öğe kaydını göster
In this study, we investigated interspecific variations of apple genotypes using ISSR (Inter-Simple Sequence Repeats) and RAPD (Randomly amplified Polymorphic DNA) technique. Total 19 genotypes of wild grown local varieties were collected from Eastern Black Sea region of Turkey and have been studied for the analysis of ISSR and RAPD profile to examine their relationship. From total 53 RAPD and ISSR primer investigated, 28 could amplify clearly and consistently. All bands obtained from ISSR and RAPDs primer were polymorphic. The dendrogram realized from the RAPD and ISSR markers grouped the 19 genotypes into two major clusters. Cluster I comprised 'Bey Apple', 'Fatty Apple', 'Golden Delicious', 'Yellow Belly Apple', 'Bride Apple', 'Green Belly Apple', 'Summer Apple', 'Yomra Apple', 'TavAYanbaAYA +/-', 'Black Belly Apple', 'Chest Apple', 'Local Marble', 'English Apple', 'Willow Apple', 'Arabian Girl', 'Yellow HA +/- dA +/- r' and cluster II contained 'Starking Delicious', 'Mahsusa', 'Amasya Marble'. Genetic diversity data from this study will be helpful in using and exploiting the wild genetic material for breeding purposes as well as for further research.
