title: [Marking the Vrd1 gene in the bread winter wheat].
abstract: PCR analysis was used to create DNA markers to the Vrd1 gene. DNA of almost isogenic lines with respect to Vrd genes of the cultivars Mironovskaya 808 and Erytrospermum 604 was used. It was shown that in the monogenic Vrd1 dominant genotypes the product of amplification (280 b.p.) is absent in comparison with the DNA of the vrd recessive and monogenic Vrd2 dominant genotypes. The linkage of the marker with the Vrd1 gene has been determined using DNA analysis of plant population obtained as a result of crossing of Erytrospermum 604 (vrd recessive) and Triple Dirk C (Vrd1vrd2). F2 population segragated in two groups on the character of 280 b.p. amplification product "presence/absence". The segregation significantly coincided to the theoretical one (by ?2 test) with 1:3 expectation. The revealed molecular marker identified homozygous dominant Vrd1 plants only. The DNA-marker to Vrd1 gene is nulle-allelic 280(-).
