| Research Abstract |
Apple cultivar 'Wijcik' is a columnar mutant of 'McIntosh'. Columnar growth habit of 'Wijcik' is characterized by compaction of the internodes and reduced lateral shoot growth, and controlled by a single dominant gene, Co, on linkage group 10. In this study, we identified three SSR markers (Mdo.chr10.12, 10.13 and 10.14) that co-segregated with Co by fine mapping. Mdo.chr10.12 and 10.14 are well suited for marker-assisted selection because the sizes of the alleles linked to Co are different from those found in common ancestors of current apple breeding germplasm. We delimited the Co region between SSR markers 11-1 and 14-3, and identified an insertion mutation in the Co region.
