- Аннотация: Phytophthora infestans strains collected from the Northern Caucasus during 2001 and 2002 (3 field populations from Northern Osetia, Ingushetia, and Stavropol Region (Kislovodsk)) were analyzed on the mating types, resistance to fungicide metalaxyl, izozyme loci Pep-1, Pep-2, and Gpi, haplotypes of mitochondrial DNA, potato and tomato races, occurrence of the oospores. In the populations mating types A1 and A2 were in comparative ratio, rare oospores were found. Majority of tested isolates were sensitive to metalaxyl. Complex potato races predominated in all studied populations, virulence genes R1 - R4, R7, R8, R10 and R11 were often, R5, R6 and R9 were rare. Maximal race diversity was found in the population from Ingushetiya. Tomato race T0 also predominated in all investigated populations except population from Ingushetiya where ratio T0:T1 was about 1:1. All isolates were 100/100 at Gpi-1 locus. At locus Pep-1 the genotype 100/100 prevailed, the frequency of heterozygote 92/100 was very low (4-14%). At locus Pep-2 genotype 100/100 also prevailed, but heterozygote 100/112 occurred often, too. The ratio of Pep-2 genotypes is in accordance with Hardy-Wainberg equilibrium at 95% level of significance. Mitochondrial haplotypes IIa and Ia occurred in the populations, other described haplotypes were not found. Genotype 112/112 was the rarest; it was identified only in the Northern Osetiya and Ingushetiya (12% and 9% respectively). So, it evidences about possibility of some income of sexual reproduction in P. infestans populations diversity in the Northern Caucasus.
