چکیده
The Michurinsk State Agrarian University (Michurinsk SAU) is one of the leading centers for breeding apple clonal rootstocks. A diverse collection rootstocks, founded in 1930s by V.I. Budagovsky, maintained at SAU. In present study, 87 rootstocks from this were analyzed using 18 SSR markers to assess their genetic diversity and relatedness. detected polymorphism level was rather high compared previous estimates rootstock variability. total 199 alleles with an average 11.1 per locus. Among alleles, 67 (33.67%) rare 43 (21.61%) unique. PIC value 0.73, expected observed heterozygosity averaged 0.76 0.69, respectively. All studied accessions except two could be identified used marker set. Cluster analysis revealed several groups according rootstocks’ pedigrees origin. Furthermore, Structure main accessions. No significant differentiation sample dwarfing ability detected, while weak leaf color. genotyping data can fingerprinting pedigree verification will facilitate management. addition, on structure may useful further development SAU program.
