Fig. 4.1 Scheme for deve loping a Mv9kr1 line fr om a Mv9 × CS hybrid via backcrossing with
Mv9. Progenies were selected based on the seed set obtained when pollinated with rye. After each
backcross two self-pollinated generations were tested for crossability with rye in order to select
plants which carry crossability allele kr1 in the homozygous state
