| Abstract: | The behavior of sexual reproduction of Phytophthora drechsleri was studied by the crosses ofwild type parents with double-marker(drug-resistantce).Parental isolates Phy 607(A-1)and Phy 64(A_2) were reisitant to actidione and sensitive to neomycin,and Phy115(A_1)and Phyll2(A_2)wereresistant to neomycin and sensitive to actidione.From the crosses of isolates Phy607xPhy112,Phy115xPhy64,single-oospore cultures resistant to both actidione and neomycin were 37% and 50% of the total iso-lates respectively in F_1 progenies.Results also showed that those four parental isolates formed oospores bythe stimulation of hormone from the opposite mating type isolates.It is suggested that,three manners ofoospore formation might be present in the cross of intraspecific isolates of P.drechsleri,includinghybridization,and self-fertilization of both parents.However,hyridization might play an important partin sexual reproduction. |
