[Genetics determination of wheat resistance to Puccinia graminis F. sp. tritici deriving from Aegilops cylindrica, Triticum erebuni and amphidiploid 4].

The lines of winter soft wheat developed in the Plant Breeding and Genetics Institute contain new effective introgressive Sr-genes. Line 85/06 possess SrAc1 gene, lines 47/06, 54/06, 82/06, 85/06, 87/06, 238/06, and 367/06 possess SrAc1 and SrAc2 derived from Aegilops cylindrica, line 352/06 - SrTe1 and SrTe2 from Triticum erebuni, line 12/86-04 - SrAd1 and SrAd2 from Amphidiploid 4 (Triticum dicoccoides x Triticum tauschii).

[Genetic determination and inheritance of resistance to Fusarium graminearum L. in wheat].

A genetic basis of resistance of winter wheat to Fusarium graminearum causing Fusarium head blight was defined as a result of F1, F2, BC1 hybrid analysis in the crosses of some lines and varieties with highly susceptible variety Odesskaya polukarlikovaya. It was found out that resistance to Fusarium graminearum inherited regardless of resistance to rust, mildew and Septoria.
