Abstract
Goal. To define optimal conditions for storage of bread wheat seeds of several varieties after reproduction at
some research institutions of
Results and Discussion. The seed germinability of bread wheat (Triticum aestivum L.) varieties was
monitored: 67 accessions of lutescens,
49 accessions of erithrospermum and several
accessions of graecum, ferrugineum, milturum, which were stored with the seed moisture content of 5-8% under
controlled conditions. Seeds of these accessions were reproduced in the Plant
Production Institute nd. a. V.Ya. Yuriev of NAAS (Eastern Forest-Steppe of
Conclusions. The seed moisture content of 6-7% is recommended for long-term storage of
seed accessions of different bread wheat varieties in the National Depository. The
initial seed germinability is expected to be preserved for up to 10 years with
this seed moisture content and at unregulated temperature in the Depository. To
prolong the period of maintenance of the initial seed germinability, storage at
