“…Consequently, the restoration of fertility of alloplasmic lines under study correlates with the male parent type of mtDNA which substitutes maternal type during backcrossing. This result agrees well with the previous data obtained using Hordeum x Triticum alloplasmic hybrids [36]. An exception is the D-n-05 line, in which the patterns of markers for the rps19-p and orf256 genes were similar to the parental species T. dicoccum.…”

Tetraploid species T. dicoccum Shuebl is a potential source of drought tolerance for cultivated wheat, including common wheat. This paper describes the genotyping of nine stable allolines isolated in the offspring from crossing of T. dicoccum x T. aestivum L. using 21 microsatellite (simple sequence repeats—SSR) markers and two cytoplasmic mitochondrial markers to orf256, rps19-p genes; evaluation of drought tolerance of allolines at different stages of ontogenesis (growth parameters, relative water content, quantum efficiency of Photosystem II, electron transport rate, energy dissipated in Photosystem II); and the study of drought tolerance regulator gene Dreb-1 with allele-specific PCR (AS-MARKER) and partial sequence analysis. Most allolines differ in genomic composition and T. dicoccum introgressions. Four allolines—D-b-05, D-d-05, D-d-05b, and D-41-05—revealed signs of drought tolerance of varying degrees. The more drought tolerant D-41-05 line was also characterized by Dreb-B1 allele introgression from T. dicoccum. A number of non-specific patterns and significant differences in allolines in regulation of physiological parameters in drought conditions is identified. Changes in photosynthetic activity in stress-drought are shown to reflect the level of drought tolerance of the forms studied. The contribution of different combinations of nuclear/cytoplasmic genome and alleles of Dreb-1 gene in allolines to the formation of stress tolerance and photosynthetic activity is discussed.

“…These resistance traits may have been transferred to wheat due to the crossability of wild barley with bread wheat. Chromosomes from H. marinum could be introduced into common wheat through wheat-barley hybrids and back crossing to wheat Trubacheeva et al, 2009). Introgressed segments can be assessed by in situ hybridisation, which readily distinguishes H. marinum chromosomes from those of wheat .…”

We evaluated the applicability of seventy-eight H. vulgare EST markers for studying bread wheat-H. marinum subsp. gussoneanum substitution and addition lines. Of all the markers studied, thirty-six (46%) were amplified in H. marinum ssp. gussoneanum and wheat introgression lines. The identification of wild barley chromosomes using EST markers confirmed the GISH and C-banding data. Thus, it was established that the H. vulgare EST markers can be successfully used to identify the chromosomes of H. marinum subsp. gussoneanum in introgression lines of wheat.
