The aim and tasks of the study. Determination of the optimal seed storage conditions for rye seed samples after monitoring results under model experiment.
Materials and methods. The material for the study were samples of seeds of rye: sterility maintainers L.1201 B L.961358 B L.90691 B L.120337 B; hybrid populations: Koroleva, Kharkiv'yanka and sterile line L.1201 A, L.90691A. Seeds were dried to moisture content 5, 6, 7% and kept in conditions of model experiment "accelerated aging" at 37 °C during 12 months. Monitoring of seed viability was performed after 4, 8 and 12 months of storage by seed germination test and length of seedlings.
Results and discussions. In model terms "artificial aging for 12 months" conducted monitoring of the seed lines and varieties of rye with a moisture content of 5-7% in terms of vigor, germination and seedling length. The low humidity conditions can be traced decisive influence genotype than the variation of the moisture content in the investigated range.
Seed germination after 4, 8, 12 months of seed storage under modeling conditions have lower indexes for lines L.1201 A, L.90691 A, compared with the majority of sterility maintainers and rye varieties. The length of the seedlings doesn’t always image the influence of storage conditions on the population status of seeds. There was advantages of the effect of genotype on seed moisture level in the range of 5-7% for the life of the
Conclusions. The most of the samples of rye in the conditions of model experiment show the benefits of endurance to store seeds with moisture content 5 and 6 %. There was a lower performance storage capacity for sterile lines L.1201 A, L.90691 A than majority- sterility maintainers and hybrids of rye. Seedling length does not always demonstrate the effect of storage conditions influence on the state of populations seeds.
