Molecular characterization of a diverse Iranian table grapevine germplasm using REMAP markers: population structure, linkage disequilibrium and association mapping of berry yield and quality traits

In this study forty-five table grape Iranian cultivars were assessed by using 42 retrotransposon-microsatellite amplified polymorphism (REMAP) markers also analyzing population structure, linkage disequilibrium and genomic regions associated with most important berry yield and quality traits. The phenotypic results showed the great diversity of the Iranian germplasm and their suitability for genetic and association studies. The studied grape cultivars were divided into three populations. A significant level of LD was observed in 1.22% of the retrotransposon marker pairs ( P
