The inheritance was determined for the reaction of strawberry to Alternaria alternate strawberry pathotype and its host-specific toxin (AF-toxin). Susceptible cv. Morioka-16 and resistant cv. Hokowase were used for the crosses. Susceptibility to the pathogen and sensitivity to the toxin were both inherited as a single locus with two alleles expressing incomplete dominance when heterozygous. Susceptible cv. Morioka-16 was found to be susceptible heterozygote and resistant cv. Hokowase was found to be resistant homozygote. Furthermore, susceptible homozygote selected from F1 progenies was more susceptible to the pathogen and also more sensitive to AF-toxin than cv. Morioka-16, susceptible heterozygote.
