Aim. Determination of molecular genetic polymorphism of maize varieties and lines (Zea mays L.) of Ukrainian and world selection by Dhn1 and ZmDHN13 dehydrin genes. Methods. Polymerase chain reaction (PCR), PAAgel-electrophoresis. Results. Maize varieties and lines of different geographical origin and different years of creation were analyzed by Dhn1 and ZmDhn13 dehydrin genes. Conclusions. The use of directional primers revealed five different alleles of the Dhn1 locus, which differed in the size of the amplification product: 186, 190, 194, 196 and 200 bp. The most common allele was 196 bp (46.2%). Two alleles of the ZmDhn13 locus were detected: 86 bp and 82 bp. Allele frequency 86 bp was 61.5% and the allele frequency 82 bp was 38.5%. The sequences of the dehydrin genes Dhn1 and ZmDhn13 are not conservative, deletions and / or insertions within these genes are observed. Accordingly, the structure and functional activity of the dehydrin proteins that encode these genes in different genotypes can vary greatly. Keywords: Zea mays L., dehydrins, genes, drought resistance.

Determination of reduction in leaf photosynthesis due to drought conditions is complicated by plant-to-plant variability in the progressive onset of drought stress. In this study a method of analysis was developed to quantitatively compare the reduction in leaf photosynthesis due to drought stress for an old and a new maize (Zea mays L.) hybrid introduced 30 yr apart in Ontario.Key words: Maize, leaf photosynthesis, drought stress, non-linear fitting, hybrid difference
