Identification of segregation distortion SSR loci distributed throughout the ‘Katy’ LG3, using data from subsets of the outcrossing populations ‘H×K’, ‘G×K’ and ‘C×K’ carrying the PPM.

aMarker position (Mb) within the peach genome scaffold_3 which size estimated by IPGI was 22.02 Mb. bS-genotypes of the selected seedlings were: S1S1 and S1S4 in ‘H×K’; S2S2 and SCS2 in ‘C×K’; S1S1, S1S2 and S2S2 in ‘G×K’. cSegregation type as per JoinMap 3.0. dChi-square test was performed for the expected ratios 1∶2:1 () (a) and 1∶1 (//) (b). eObserved ratios differ significantly from expected at P<0.05 for 2 (a) or 1 degrees of freedom (b).
