Abstract

Aim. To determine the nature of the influence of flowering periods on productivity traits in soft winter wheat lines, which were created with the involvement of late-ripening samples of the Western European ecotype. Methods. Research methods are field, laboratory, selection-genetic, statistical. Results. The nature of the manifestation of the "date of flowering" trait in hybrids F1-F3 and selection numbers selected from hybrid populations with the participation of Western European ecotypes of soft winter wheat, the correlation dependence of the date of flowering, grain yield, ear length and the duration of the "flowering-maturity" period were established. Optimums for the manifestation of indicators that determined high yield and ear length were established. Conclusions. For each hybrid population created with the participation of parental components contrasting in duration of vegetation, it is necessary to develop a specific selection plan taking into account intra-population correlations of yield, flowering dates and the duration of the "flowering-maturity" period.
