[Genomic Markers Associated with Cold-Hardiness in Brassica rapa L.].

Brassica rapa L. is a valuable and widespread species, but its cultivation in risk farming areas requires high-quality cold-hardy varieties to be developed. Mechanisms of the cold stress response in plants involve expression of numerous genes, including ribosomal ones, and are related to plant chromosome variability.

Integration of Physical, Genetic, and Cytogenetic Mapping Data for Cellulose Synthase () Genes in Flax ( L.).

Flax, L., is a valuable multi-purpose plant, and currently, its genome is being extensively investigated. Nevertheless, mapping of genes in flax genome is still remaining a challenging task.

[The Use of Specific DNA Markers for the Identification of Alleles of the FAD3 Genes in Rape (Brassica napus L.)].

A search was conducted for the alleles responsible for the quality of food-grade rapeseed oil in a collection of 21 samples of spring and winter oilseed rape of Belarusian and Russian breeding. We also developed A- and C-gene-specific DNA markers to assess the genomic polymorphisms of rape for FAD3 genes and selected plants with a low content of linolenic acid for use in the selection process. The development of a method for identifying FAD3 alleles, which control the level of linolenic acid in rapeseed oil, as well as of the design for new dCAPS markers, enabled the identification of plants homozygous for individual FAD3A and/or FAD3C genes in the F2-generation.

[Allelic Composition in the VRN-A1, VRN-B1, and VRN-B3 Genes of Double Haploid Lines of Hexaploid Triticale].

Vernalization genes are associated with the adaptation capability, heading dates, and yield potential of grain crops. The allelic composition in the Vrn-A1, Vrn-B1, and Vrn-B3 genes was defined in 42 lines of double haploids of hexaploid triticale, which were produced through in vitro anther culture. Two alleles (Vrn-A1a and vrn-A1) were found at the Vrn-A1[ital] locus and three alleles (Vrn-B1a, Vrn-B1c, and vrn-B1) were found at the Vrn-B1 locus.
