GENETIC ANALYSES OF ENDOTHIA PARASITICA: LINKAGE DATA FOR FOUR SINGLE GENES AND THREE VEGETATIVE COMPATIBILITY TYPES

The loci cre, met and ts segregate independently in Endothia parasitica. The phenotype brown (br) seems to be determined by an allele at or very near the cre locus. The vegetative compatibility types (v-c) 5 and 39 are determined by different alleles at a locus that is not linked to cre, met or ts. Analysis of two crosses of v-c 5 strains by v-c 10 strains provides evidence that these two v-c groups are different at 5 or more v-c loci.
