The characteristics of agronomic traits in the analogue lines of the Kooperatorka and Stepnyak bread wheat cultivars, in which alleles of the photoperiod sensitivity genes were identified by PCR, were studied. The level of recovery of the recurrent genetic background has been identified in the analogue lines, and the allelic state of the Rht8 dwarfing gene has been identified. The effect of the Ppd-D1a allele on the agronomic traits and growth rates of analogue lines, irrespective of other genetic systems, has been established, using the methods of dispersion and discriminant analyses. Differences in the results obtained by these two methods are explained by including intertrait correlations into the discriminant analysis. It has been shown that the most informative traits for discriminating between the lines were the date of heading and the plant height.
