The experience was carried out on the basis of the Far Eastern Agricultural Research Institute (Khabarovsk Territory) from 2018 to 2020. The object of research is a collection of spring bread wheat. As a result of the research, samples with the minimum duration of the growing season (72-75 days) were identified: Dian 81 V-418 (China); Calispero (France); KWS 240-3-13 (Germany); Libertina, Odeta, Kitri (Czech Republic); Iset 45, Nerda, Chelyaba rannyaya (Russia). A high grain yield (38.3–52.2 centner/ha) was noted in the collection varieties – Chi Mai 1, Dian 81 V-418 (China); Boett (Sweden); KWS 240-3-13, KWS Jetstream (Germany); Lyubava, Laska, Sudarynya (Belarus); Yoldyz, Al Varis (Tatarstan); Kitri, Odeta (Czech Republic); Calispero, Eleganza, Cornetto (France); Sibirskaya 24, Iset 45, Grenada, Klara, Kalinka, Nerda, Start, Burlak, OmGAU 100, Tulaykovskaya 116 (Russia), exceeding the standard variety Khabarovskaya by 1.3–15.2 centner/ha. The largest grain (35.1–46.7 g) formed genotypes FAO 26.415 (Afghanistan); Chi Mai 1, Dian 81 V-418 (China); Hayat, Yoldyz, Bulyak, Al Varis (Tatarstan); Libertina, Odeta, Kitri (Czech Republic); Cornetto (France); KWS 240-3-13, KWS Jetstream (Germany); Sibirskaya 24, Grenada, Klara, Kalinka, Nerda, Start, Burlak, Ekada 214, Stolypinskaya 2, OmGAU 100, Omsk yubileynaya, Botanicheskaya 81, Tulaykovskaya 116, Kinelskaya volna, Iren 2 (Russia). It was found that the Boett variety (Sweden) was characterized by high resistance to lodging in the agroecological conditions of the region. The selected collection samples are a valuable source material, and are of interest for further breeding work to create highly productive varieties of spring bread wheat under the conditions of the Khabarovsk Territory.
