Abstract
Climatic changes in recent years and changes in the areas of different cultures have had an impact for reducing of the plant resistance to pests and diseases, increasing of the appearance of new diseases or strengthening the known ones.Alternariosis is the most damaging disease of tomatoes encountered lately in the Republic of Moldova. The reaction of parents-varietes and reciprocal hybrids of tomato F1 under the action of theA. solani, A. consortiale, A. alternate filtrates was manifested differently at seeds germination, root and stem growth: inhibition, stimulation or unresponsiveness. By bifactorial analysis of variance was found that at the stage of germination the genotype (86.6 to 89.7%) has the majority of the influence in the reaction of parents and reciprocal hybrids of F1 tomatoes under the action of the filtrates from Alternaria spp. culture. Trifactorial analysis of the relations tomatoes genotype x Alternaria species x isolates, based on the root reaction, has demonstrated that 65.1% depends on the genotype, 11.3% - are due to the genotype x Alternaria species interactions and 9.1% - depends on the genotype x isolate interaction. The obtained data reveal that the creation of the tomatoes genotypes, resistant to this disease, by the selection useful genotypes has a real chance of success.
