The raw genotyping data is supplied in supplementary details (Extra file 1: Table S1). To analyze only highquality SNP information, markers with 4 or additional missing information (about 300 SNPs in all) had been eliminated in the information set. Noninformative SNPs, i.e., those which are monomorphic and are for that reason not segregating, have been also eliminated, resulting lastly in 3630 polymorphic markers. The marker segregation was tested against a typical Mendelian expectation ratio (1:1) so as to analyze segregation distortion, and these markers displaying segregation distortion (stated at 0.05) had been eliminated to prevent map artifacts. Therefore, a total of 2865 polymorphic SNPs (40 on the total) were identified (Table 1) and chosen for their respective map construction, from which 1970 segregated (1:1) for the `MxR_01′ parent and 895 for `Granada’. An instance of the way we proceeded is shown in Further file two: Figure S1. A total of 282 polymorphic SNPs were situated in scaffold (Sc) 1 with the peach genome assembly v1.4,6-Dichloropyrimidin-5-amine site 0 segregating for the `MxR_01′ parental. Of those, 265 markers could possibly be grouped and ordered inside a single linkage group with several markers cosegregating in the identical position (Extra file 2: Figure S1). One particular SNP for each position was selected (26 in all) to get a simplified map. Similarly, maps corresponding for the other scaffolds (3, 4, five, 6, 7, and 8) have been obtained with the exception of Sc2, for which the map was not constant with all the expected genome position and had substantial gaps (higher than 30 cM), and was discarded for becoming not appropriate for QTL evaluation. A total of 178 SNPs had been located in the `MxR_01′ simplified map, representing a total distance of 480 cM (Table 1). The marker density varies in between 1.98 cM/marker (for LG8) to 4.08 cM/marker (for LG6). On typical, one marker per two.94 cM was found inside the `MxR_01′ map.SNPs chosen MxR_01′ 26 0 40 29 14 15 21 33 178 Granada’ 0 13 0 10 8 20 16 7Map distance (cM) MxR_01′ 75.01 0 87.28 69.95 50.eight 61.18 70.45 65.37 480 Granada’ 0 59.08 0 22.46 39.61 75.75 50.87 16.70Marker density (cM/marker) MxR_01′ 2.89 X two.18 two.41 3.63 four.08 three.35 1.98 Granada’ X four.54 X two.25 four.95 3.79 three.18 2.For each scaffold, the total number of SNPs present inside the array (Total SNPs) and the number of polymorphic markers with the percentage of the total (in parentheses) are indicated.

X indicates those situations where there were not sufficient markers to make a genetic map and for which marker density could for that reason not be calculated.S chez et al. BMC Plant Biology 2014, 14:137 http://www.biomedcentral.com/14712229/14/Page 5 ofFor `Granada’, a decrease number of polymorphic markers was obtained as compared to `MxR_01′ (Table 1). Following exactly the same approach as described for `MxR_01′, the maps for Scs two, four, five, six, 7, and eight have been obtained for `Granada’. No map was obtained for Sc1 and Sc3. Only the linkage groups of Sc6 and Sc7 showed evenly distributed marker.
