Abstract

New genetic sources for enrichment bread wheat genofond of valuable breeding traits were developed by introgressive hybridization. Using for crossings of  bread  wheat with relative speciese and amphiploids are long-term for breeding : for productivity – T. turgidum, T. turanicum; for grain quality– T. sphaerococcum, T. dicoccum, T. polonicum, T. compactum, Ae. cylindrica; amphiploids Avrotica, AD 221-4, AS 7, ПЕАГ, T. miguschovae ; for resistance against causative agents of separate disease and its complex– T. turgidum, T. durum, Ae. cylindrica; amphiploids Avrotica, AD 221-4, AD 7, ПЕАГ, T. miguschovae, for resistance against Tilletia caries (DS) – Avrotica, and T. miguschovae. Frost resistant forms of wheat were obtained  of crossing withT. turgidum, T. durum, Ae. cylindrica, Avrotica, AD 221-4.

It is necessary to use early ripening dwarf and semidwarf   bread wheat varieties for crossings with relative speciese and amphiploids of wheat. Last years more 60 lines from distant hybrids were included in breeding programs as sources  and donors of valuable traits.
