A total of 88 individuals (17 %) had all four marker alleles associated with the CMD2 gene. In these individuals, themost probable source of CMD resistance is CMD2. A total of 179 individuals had between one to three marker alleles each associated with CMD2. The
progenitors Dabodabo and TMEII were phenotypically resistant. TMEII appeared consistent with the CMD2 gene resistance (showing bands present for alleles of this gene in three markers). However, Dabodabo was less consistent, showing presence of bands for the corres pondingallele for CMD2 gene resistance in only one of the four markers and may represent a new possible source of CMD resistance gene(s). The further use of
Dabodabo in crosses with susceptible CMD parent(s) to test for new CMDresistance gene in this landracewould confirm the observation.
