The Effect of Chromosome Arm 1BS on the Fertility of Alloplasmic Recombinant Lines in Bread Wheat with the Cytoplasm.

The genetic mechanisms of fertility restoration in alloplasmic bread wheat with the barley cytoplasm are poorly explored. The effect of the 1BS chromosome arm on the fertility of bread wheat with the cytoplasm was studied depending on the incompleteness/completeness of the cytonuclear compatibility. (i) Three self-fertile (SF) lines and one partially fertile (PF) line with an incomplete cytonuclear compatibility and (ii) four self-fertile (SF) lines with a complete cytonuclear compatibility were studied.

Study of Androgenic Plant Families of Alloplasmic Introgression Lines () - and the Use of Sister DH Lines in Breeding.

One of the limitations in obtaining the genetic diversity of doubled haploid (DH) lines via anther culture is the development of families of regenerants, and each family represents a clone. This work examines the results of studying this phenomenon in anther culture of alloplasmic ()- and euplasmic lines with 1RS.1BL and 7DL-7Ai translocations and hybrids between them.

[Chromosome composition of wheat-rye lines and the influence of rye chromosomes on disease resistance and agronomic traits].

Identification of the chromosomal composition of common wheat lines with rye chromosomes was carried out using genomic in situ hybridization and 1RS- and 5P-specific PCR markers. It was demonstrated that wheat chromosomes 5A or 5D were substituted by rye chromosome 5R in the wheat-rye lines. It was established that one of the lines with complex disease resistance contained rye chromosome 5R and T1RS.

[Characteristics of common wheat cultivars of West Siberia carrying the wheat-rye 1RS.1BL translocation].

Using genomic in situ hybridization, among the common wheat cultivars produced in West Siberia (Siberian Research Institute of Agriculture, Omsk) with the involvement of the winter wheat cultivar Kavkaz carrying the wheat-rye 1RS.1BL translocation we identified three cultivars with this translocation: Omskaya 29, Omskaya 37, and Omskaya 38. The protein and crude gluten contents in the grain of these cultivars are equal to or exceed the levels observed in cultivars without the wheat-rye translocation.
