Study of donor properties of common wheat cultivars that are source of resistance to <i>Septoria nodorum </i>Berk
Study of inheritance seedling resistance to Septoria nodorum Berk of 8 common spring wheat and 18 common winter wheat demonstrated that more efficient donors of this traits are cultivars Burgas 2, Jamhill, Flex, Hand, Sage, Coker 47-27 and Fiume. Winter accessions - Burgas 2 and Jamhill have only recessive juvenile gene. The resistance of spring cultivars Coker 47-27, Fiume and winter crops Flex, Hand, Sage is controlled by two complementary recessive genes. The rest of studied spring crops cultivars (Coastal, Cotipora, Frondoso, Mara, Toropi, IL-1) and samples of winter cultivars (Carifen 12, Coker 68-8, Harvest Queen, HC, Neuzuchtung, Redhart, Transfer, Disponent, Moro, Oenus, Wiehenstephan 625/65, Zarya, PI 525450) have 3-4 resistance genes with complex interaction.
