Genetic Diversity and Core Germplasm Research of 144 Munake Grape Resources Using 22 Pairs of SSR Markers

The Munake grape is a local variety of that widely distributed in Xinjiang, China. This study aims to clarify the genetic structure population, characterize differentiation and gene flow among populations, gather germplasm, establish core germplasm collection. In total, 144 samples were collected from eight geographic populations. Twenty-two SSR markers used diversity as well At each site, average number effective alleles (Ne) was 5.019. Overall, high various populations grapes. Polymorphic information content (PIC) ranged 0.501 0.908, with an 0.728. Estimates indicated Artux population had significant differences other Screening results sampling proportion 95% sample required achieve 100% allelic coverage, or 65% for coverage. analysis based on conventional indicators, index Characterization grapes not only provides valuable resources future mapping functional genome research, but also facilitates utilization molecular breeding
