MOLECULAR AND GENETIC CHARACTERISTICS OF THE COLLECTION OF WHEAT VARIETIES (TRITICUMAESTIVUM L.) BY THE ALLELIC COMPOSITION OF THE PHOTOPERIOD SENSITIVITY GENE PPD-D1 AND GENES ENCODING THE CBF FACTORS OF THE FR-B2 LOCUS
The allelic composition of the Ppd-D1 gene influencing the photoperiod sensitivity, as well as the presence/absence of deletions in the Fr-B2 locus, affecting frost tolerance in the collection of 98 varieties of spring and winter wheat, was investigated. It is shown that the alleles of genes associated with cold tolerance have spread in Belarusian wheat cultivars.
