• This QTL fro T. dicoccoides explains gt37 of the
  phenotypic variation in a durum cross.
• Selection will be done using microsatellite
  markers Xgwm2 and Xgwm674.
• Otto et al. 2001. Plant Mol. Biology in press

• QTLfhs-3BS from Sumai3 3BS explains up to 40 of
  the phenotypic variation
• Selection will be done using microsatellite
  markers Xgwm533 and Xgwm493
• This QTL is expected to reduce FHB severity by
  approximately 50

Eyespot resistance genes Pch1, Pch2
Pch1 located on chromosome 7DL can be identified
through its linkage with the Ep-D1b band of
endopeptidase. McMillin et al. (1986) TAG 72
743-747 Pch2 located between RFLP loci Xwg380
and Xcdo347 on chromosome 7A.delaPeña et al
(1997). Genome 40 249-252.
