The influence of alternative alleles of the Ppd-D1 gene, differences in the duration of the need for vernalization the presence or absence of ear awns and anthocyanin coloration of the stem in plants of 164 recombinant F7 winter bread wheat lines from a complex combination of crossing varieties of different geographical origin [F1 (Chaika//Cappelle Desperez/2B Chinese Spring) / Kharkiv 81] F2 / Obriy] on the duration of the period before earing, plant height, 1000 grain weight and grain yield was determined. Significant associations were found between all marker traits and the duration of the period before heading, the Ppd-D1a gene and the presence of awns with an increased weight of 1000 grains, as well as anthocyanin coloration of the stem with plant height. Among of the 12 lines that exceeded the grain yield of the more productive standard variety Kuyalnik, there are lines of seven genotypes with 16 different combinations of four marker traits. The awned genotypes with green stem color and the presence of the Ppd-D1a gene were more productive regardless of the duration of their need for vernalization.
