Figure Lengend Snippet: Comparison of Lr49 genetic linkage map with the 585 to 617 Mbp interval of Chinese Spring chromosome 4B physical map using Pretzel, a genetic map viewing software ( http://plantinformatics.io ). Markers distal to sunKASP _26 are colinear with the physical map (green connections). The genetic map order of markers proximal to sunKASP _21 does not reflect the physical map order in Chinese Spring (black connections).

Figure Lengend Snippet: Diagrammatic representation of the Lr49 interval and flanking region on chromosome 4B. Both VL404 (resistant parent) and WL711 (susceptible parent) have two sequence haplotypes outside the Lr49 region, while VL404 has only one sequence haplotype within the Lr49 interval. Chinese Spring has only one sequence haplotype across entire region. Each unique sequence haplotype is represented by a different color. Markers mapping within the Lr49 interval are ordered based on their physical mapping location. The Lr49 genetic map does not reflect the physical mapping order as illustrated by comparison of genetic and physical map order across the Lr49 interval. Differences in sequence haplotype structure and physical-genetic map order in VL404 and WL711, relative to Chinese Spring, suggests structural rearrangement or copy number variation (CNV) relative to Chinese Spring.
