SummaryClonal selection is an important method for varietal improvement in grapevine. Ampelometric and morphological markers fail to differentiate clones from their parent genotype. Molecular markers offer the opportunity to identify the clonal material. In this study, five clones of the grapevine variety ‘Kishmish Chernyi’ were analysed using microsatellite (SSR) and AFLP markers. These clones differed significantly in their bunch characteristics including berry size, shape, and colour. Microsatellite (SSR) analysis using 24 primers could not distinguish between these clones. The allele profiles of the clones and the parent variety were identical. AFLP analysis using 13 primer pair combinations yielded 592 markers ranging in size from 50 – 500 bp. Of these, 79 markers (13%) were polymorphic. The majority of the polymorphic markers (75/79) were detected in the clone ‘Sharad Seedless’. Three AFLP primer combinations detected unique markers in three clones which could be useful for future identification. 相似文献

Twenty-one rootstock accessions were analyzed with seven grape microsatellite (SSR) primers and seven AFLP primer combinations. SSR primers detected 56 alleles across 21 genotypes and primer heterozygosity varied from 0.617 to 0.856. Similarly 252 AFLP bands were obtained with seven primer pairs. The average similarity index for different rootstocks was relatively low and ranged from 0.068 to 0.36 for AFLP data and from 0.13 to 0.36 for SSR data. A combination of three SSR primers was sufficient to distinguish 21 rootstocks. In cluster analysis majority of rootstocks belonging to same species grouped together. Although the dendrograms obtained with two marker systems were not identical, rootstocks belonging to same species or having common parents were grouped together in both the dendrograms. 相似文献
