[Genetic diversity of local spring soft wheats (Triticum aestivum L.) of west and east Siberia in gliadin genes].

A considerable polymorphism in gliadin genes was detected in the local wheats of West Siberia (Altai krai, Omsk oblast, and Kurgan oblast) and the local cultivars characteristic of several East Siberian regions (Krasnoyarsk krai, Irkutsk oblast, Tuva, and Yakutia), and the genetic formulas were determined. The common alleles characteristic of the wheats of both regions were detected, namely, Gli-A1f, Gli-A1j, Gli-A1i, Gli-A1m, Gli-B1e, Gli-B1m, Gli-D1a, Gli-A2q, Gli-A2k, Gli-A2u, Gli-D2a, and Gli-D2q, as well as 14 novel alleles unknown earlier. It was demonstrated that several genotypes had formed in Siberia. Of them, the genotypes Gli-Alf_Gli-Ble_Gli-D1a and Gli-Alj_Gli-Ble_Gli-D1a occur both in West and East Siberia, whereas the genotypes Gli-Ali Gli-Blm Gli-D1a Gli-A2new10, Gli-A1m_Gli-B1b_Gli-D1a_Gli-A2f, and Gli-A1m_Gli-B1m_Gli-D1a_Gli-A2u are found only in East Siberia.
