We provided experiments with the seeds of 73 varieties and lines of hexaploid wheat (2016 harvest), reproduced in the Kharkiv region of Ukraine and in the Chisinau area of Moldova, to elucidate the efficiency of the elaborated accelerated method of assessing genotypes' primary resistance (excluding the adaptation processes induced during plant ontogenesis) to high temperatures and frost. We performed tests under laboratory controlled conditions to evaluate the seeds' germination capacity after exposure to specific doses of heat shock (HS) with a high temperature of +50℃ time for 30 minutes or frost shock (FS) with a negative temperature of -7℃ for 8 hours. Based on the determination of the seed germination percentage of different varieties and lines of common winter wheat exposed to HS or FS, their distribution according to their primary resistance to frost and heat stress was evaluated. The obtained results demonstrated, that by their primary resistance to HS or FS, conditionally wheat varieties and lines can be divided into three groups: with low, medium and high primary resistance to extreme temperatures, including genotypes that after exposure to a chosen dose of temperature stress germinated up to 30%, between 30 and 70%, and more than 70% of seeds, respectively. The data demonstrate that seeds' resistance to HS or FS is specific for different wheat varieties and lines. Among all of them with low, medium and high resistance to FS, respectively 38, 44 and 80% simultaneously showed increased resistance to HS. The summary number of genotypes equivalently distributed in mentioned three groups is equal to 25, which constitutes 50% of the total number of genotypes included in our research. Twelve genotypes were identified (1088, 87, 1101, Kolichuga, Toulouse, 126, 91, Odesskaia 267, 21, 1013, Ovidii and 781) which characterized by a very high plasticity and high summary primary resistance to HS and FS.
