[A study of the storage proteins in the introgression lines of common wheat (Triticum aestivum L. x T. timopheevii Zhuk.) resistant to brown leaf rust].

Storage proteins, prolamins, were studied in ten introgression lines of common wheat bred with involvement of Triticum timopheevii Zhuk. and five commercial hexaploid wheat cultivars. The lines are resistant to leaf rust. A comparative analysis of the storage proteins in the Triticum aestivum L. introgression lines and the parental forms allowed us to (1) detect the active genes of prolamins on the chromosomes homeologous groups 1 and 6 in the introgression lines of T. aestivum and T. timopheevii; (2) clarify their origin; (3) identify the chromosome attribution of the products; (4) estimate the degree of introgression and postulate the introgression mechanisms; and (5) predict the bread-making quality of these introgression lines.
