Combinations of the Ppd-D1, Vrn-A1, Vrn-B1, and Vrn-D1 gene alleles were analyzed using allele-specific primers in 56 varieties and lines of common wheat that were selected in the Lukyanenko Agricultural Research Institute. The significant influence of the combination of these alleles on the time of the beginning of the heading of the studied varieties was determined, which is manifested differently under conditions of long and short photoperiods, as well as depending on whether vernalization occurs. Molecular labeling of wheat Vrn and Ppd gene alleles allows breeders to consciously manipulate the original material (by having information in advance about the adaptive potential of the plants that are involved in the breeding process), as well as to select the allele combinations that are optimal for specific conditions of cultivation. © 2012 Pleiades Publishing, Ltd.

Pilot experiments on using molecular markers in the breeding of winter wheat that were conducted at the Lukyanenko Agricultural Research Institute are described. The most efficient methods for using markers when developing new cultivars are outlined. The genes that are responsible for valuable agronomic traits were identified in varieties that are bred at the Institute. © 2012 Pleiades Publishing, Ltd.

DNA samples of wild relatives, synthetic forms, and introgression lines of common wheat (Triticum aestivum L.) were genotyped with diagnostic molecular markers that are linked to the leaf-rust resistance genes Lr9, Lr35, and Lr47. The Lr9 gene was identified in Aegilops umbellulata and Lr35 and Lr47 were identified in Ae. speltoides. The synthetic forms Avrolata and Avrodes, in which the genomes of Ae. umbellulata and Ae. speltoides, respectively, replaced the wheat D genome, contain the Lr9 and Lr35 genes. The genomes of the introgression lines that were developed using Ae. umbellulata lack Lr9. The Lr35 gene is present in one of the introgression lines that was derived from Avrodes. Some of the wild relatives and the introgression lines may contain additional leaf-rust resistance genes. © 2012 Pleiades Publishing, Ltd.
