[Mapping of apple Co gene using SSR markers].
Columnar apple is an important genetic resource for tree form breeding of apple. In this study, 106 individuals of the F1 population derived from 'Spur Fuji' (coco)x 'Telamon'(Coco) were used as plant materials for screening SSR markers linked to gene. By bulked segregating analysis (BSA), eight SSR markers from the tenth linkage group of apple genome were tested. Finally, three of them, COL, CH02a10 and CH03d11, were identified to be SSR markers of Co gene. Linkage analysis showed that the genetic distance of COL, CH02a10 and CH03d11 to Co locus was 15.3cM, 22.2cM and 3.9 cM, respectively. On the linkage map of these markers, Co gene was located between COL and CH03d11.
