Hich detects LrcSV2 within this cross. This analysis permitted the reduction within the LrcSV2 interval between markers FSs132 and FSs122. These final two markers have been utilized to screen 708 added F2s (1292 in total). Recombinant evaluation with internal markers and rust phenotyping of 22 11 defined a smaller interval between markers FSs135 and FSs99. These two markers delimit a area of about 1.9 Mb on the CS chromosome 4BL (Figure 4).LrcSVwmcFSsFSsFSsFSsFSsFSsFSsFSsFSsFSsFSsFSsFSsFSsFSs592184048Ma rkerRust1.9Mb579365941 579366075 BI-0115 Epigenetics 580394110 580394253 581288651 581288883 582411372 582411571 582527979 582528950 583148752 583149000 583637490 583637692 584386274 584386514 585235413 585235659 587387066 587387298 588106759 588106971 589095026 589095231 589452477 589452675 590311020 590311229 590628353 590628579 591516393 591516642 591611295Pos i ti on withi n chromos ome 4B i n Chi nes e Spri ng302 327 478 528 537 740 746 860 966 1022 1058 1060 1093 1099R R R R R R R S R R R -0 0 0 11 1 1 0 1 1 0 1 0 1 1 0 0 0 1 H 1 0Recombinant01Figure four.
