SUMMARY. A gene designated Sec-N encoding secalin was mapped in the introgressive winter common wheat line Hostianum 273/97 (H273) with the wheat-rye substitution (1В)1R from the octoploid triticale AD825. F₂ seeds from cros-sing the line H273 with the line Hostianum 242/97-2 carrying the wheat-rye 1BL/1RS translocation were analysed. The studied component on the SDS-electrophoregram of total proteins was revealed to be a monomeric secalin which is encoded by the gene at the new locus Sec-N located distally with respect to the Sec-1 locus at a distance of 21,4 ± 2,5% (22,9 ± 3,1 cM). The arrangement of the secalin loci on the 1RS arm indicates that the Sec-N locus is to be homoeologous to the Gli-1 loci of common wheat.
