Duration of the period up to heading of 107 winter wheat cultivars of different origin has been studied. The most contrast for analyzed character cultivars, as well as F2 Omskaya ozimaya / Numbu Komugi individual plants were investigated with SSR-PCR methods to reveal DNA-markers for QTL of heading temps. Two loci Xgwm512 and Xgwm429 have been revealed to explain 19,3 % (part of influence of the first locus – 8,9 %, of the second – 10,4 %) differences in duration of the period up to heading of the F2 individuals in field conditions.

Key words: winter bread wheat, PCR-markers, QTL, heading
