Studying varieties of winter durum wheat in interstation test on economic and valuable features

Abstract

The purpose of the research was to identify sources of economically valuable traits of winter durum wheat for their further use in the breeding process. The material for the research was 53 varieties of winter durum wheat of various ecological origins: Federal State Budgetary Scientific Institution, Agrarian Research Center “Donskoy”, Federal State Budgetary Scientific Institution “National Grain Center named after P.P. Lukyanenko”, Federal State Budgetary Scientific Institution “North Caucasian Federal Scientific Agrarian Center” (Russia) and Selective Genetic Institute (Ukraine). High frost resistance characterized the following varieties: Helios (90.9%), Bosphor (91.1%), Lakomka (92.2%), Terra (92.9%), Amazonka (93.0%), Aksinit (94.6 %), Cyprida (95.4%). The sources of early ripeness were varieties: Diona, Krucha, Donskoy yantar, Helios, Continent, etc., heading, which was noted from May 20 to 22; short stems: Kurant (77.4 cm), Diona (83.6 cm), Donskoy yantar (84.2 cm), Aqueduct (84.9 cm), Zhivitsa (84.6 cm), Continent (85.1 cm) , Laska (85.1 cm); coarse grains: Yakhont, Lakomka (40.3 g), Krucha (41.2 g), Belka (41.5 g), Siniora (41.6 g), Odari (43.0 g), Continent (43.2 g ), Bella (44.5 g), Bosphor (45.3 g); high productivity: Amazonka (8.86 t/ha), Yakhont (8.90 t/ha), Lakomka (9.60 t/ha), Donskoy yantar (8.87 t/ha), Krupinka (9.20 t / ha), Belka (9.21 t/ha), Siniora (9.24 t/ha), Gavan (9.28 t/ha), Citrina (9.65 t/ha), etc. Identified genotypes of valuable traits and properties can contribute to the implementation of breeding programs to create varieties of winter durum wheat.
