title: [Detection of genetic determinants that define the difference of near-isogenic Triticum aestivum L. Lines in photoperiodic sensitivity].
abstract: Identification of genetic determinants that define different degrees of line sensitivity to the photoperiod was conducted on material of near-isogenic lines of the soft hexaploid wheat Triticum aestivum L. using SSR markers and markers specific to the Vrn and Ppd genes. It was established that the Ppd-s line contains a dominant Ppd-Dla allele located on chromosome 2D. This allele is characterized by a vast deletion in the gene promoter region. For two other lines (Ppd-m and Ppd-w), introgression of the Ppd-B1 gene on chromosome 2B was shown from the parental Sonora variety, which is slightly sensitive to the length of the day; however, the previously described Ppd-Bla. 1 allele was not found. Another polymorphism that can cause weak photoperiodic sensitivity, an increased amount of the Ppd-B1 gene copies, was detected for these lines.
