Multiple marker analysis was used to screen for the CMD2 gene, where four markers associated with this gene were used. Of the tested genotypes 83 % showed at least one marker allele for the CMD2 gene. Two CIAT genotypes (CR52A-31 and AR14-10) had all four marker alleles. TMEII had three alleles associated with CMD2 while Dabodabo had one
marker allele. This suggests that Dababo may have alternative genes than CMD2 for CMD resistance. The F1 families showed segregation for the CMD2 gene. A total of 88 individuals (17 %) had all four marker alleles associated with the CMD2 gene. A total of 179 individuals had between one to three marker alleles each associated with CMD2. A total of 91 individuals had no marker allele associated with the CMD2 gene
