“…The material for the study was wheat-barley (T. aestivum-H. marinum ssp. gussoneanum Hudson 4x) ditelosomic (DT) substitution lines of the homoeologous group 7 chromosomes (Efremova et al 2013;Efremova et al 2018). To obtain substitution lines, the 44-chromosomal ditelosomic addition line (2n = 44 = 42 + 2 t) with the telocentric chromosome 7HL mar of the wild barley H. marinum, derived from common wheat cv.…”

The effects of alien substitutions of chromosomes on the heading time of ditelosomic (DT) wheat-barley substitution lines in which the chromosome 7HL mar from Hordeum marinum ssp. gussoneanum 4x replaced the chromosomes 7A, 7B and 7D of common wheat were studied. The plants were grown under short and long day illumination in greenhouse and in the field. The lines studied were found to differ in response to the length of the day. Under short day conditions, DT7HL mar (7B) and DT7HL mar (7A) showed an increase in the period before heading. In this case, the substitution effect of chromosome 7B was more significant than the effect of chromosome 7A. Under these conditions, the substitution of chromosome 7D did not have a significant effect on the heading time. Under long day conditions in the greenhouse and under natural conditions of a long day in the Novosibirsk region, substitution lines came into ear earlier than under a short day conditions and did not differ in the heading time. Allele-specific primers established the allelic composition of the genes Vrn-A1, Vrn-B1, Vrn-D1 and Vrn-B3 in ditelosomic lines. It was shown that the two DT7HL mar (7A) and DT7HL mar (7D) lines have the same genotype -VRN-A1b/VRN-B1c/vrn-D1/ vrn-B3 and that the DT7HL mar (7B) line has the genotype -VRN-A1a/VRN-B1c/vrn-D1. The results show that regardless of the genotype for the Vrn genes, the wheat-barley substitution lines react to the change in the photoperiod, especially in the absence of chromosomes 7B and 7A.

“…Pyrothrix 28 (Pyr28), was used as the paternal form for pollinating monosomic 7A, 7B and 7D lines of common wheat cv. Saratovskaya 29 (S29) (Efremova et al 2013). Among the F 1 hybrids obtained, plants with a chromosome configuration in metaphase 1 (M1) meiosis of 20" + 1' + t' were selected.…”

“…A practical application of the present findings is the detection of individual H. marinum chromosomes in breeding lines—for example, the material obtained in breeding programs after the hybridization of wheat with this interesting and complex salt- and waterlogging-tolerant group [ 21 , 22 ]. Several substitution lines with improved tolerance have been developed and are available for further use [ 20 , 23 ].…”

Crop Wild Relatives (CWRs), as potential sources of new genetic variants, are being extensively studied to identify genotypes that will be able to confer resistance to biotic stresses. In this study, a collection of barley wild relatives was assessed in the field, and their phenotypic variability was evaluated using a Barley Description List, reflecting the identified ecosites. Overall, the CWRs showed significant field resistance to various fungal diseases. To further investigate their resistance, greenhouse tests were performed, revealing that several CWRs exhibited resistance against Fusarium culmorum, Pyrenophora teres, and Puccinia hordei G.H. Otth. Additionally, to characterize the genetic diversity within the collection, DNA polymorphisms at 21 loci were examined. We successfully employed barley-specific SSR markers, confirming their suitability for identifying H. spontaneum and even H. marinum, i.e., perennial species. The SSR markers efficiently clustered the investigated collection according to species and ecotypes, similarly to the phenotypic assessment. Moreover, SSR markers associated with disease resistance revealed different alleles in comparison to those found in resistant barley cultivars. Overall, our findings highlight that this evaluated collection of CWRs represents a valuable reservoir of genetic variability and resistance genes that can be effectively utilized in breeding programs.

“…Several studies have been carried out on alloplasmic lines of wheat with the cytoplasm of Triticum, Aegilops, Secale, and Agropyron (Reddy et al, 2015;Gavrilenko, Yermishin, 2017;Iefimenko et al, 2018;Kondratskaya et al, 2018). Alloplasmic lines of Hordeum, Solanum, Gossipium, Brassica, Avena and other genera containing the cytoplasm of relative species were obtained (Efremova et al, 2013;McGrath et al, 2015;Iefimenko et al, 2018). Research on the genetics of crop immunity has identified the prospects of using wild species in breeding to protect crops from pests and diseases and to enrich the adaptive potential of crops (Zaviryukha et al, 2017).…”

The purpose of the study was to obtain new breeding genotypes containing a nuclear genome of a sugar beet sterility maintainer and sterile cytoplasm of wild beet (Beta patula L.). The donors of a new sterile cytoplasm of B. patula plants were selected by the indirect cytological traits of cytoplasmic male sterility (CMS), especially pollen sterility, abnormal development of the anthers, mosaic patterns of anthers and flowers. The anthers were examined for morphological traits of pollen and microspore degeneration in CMS. During reciprocal crosses, (i) the expression of recessive alleles of the nuclear genes of the CMS sterility maintainers was analysed, (ii) the peculiarities of hybridisation of the experimental genotypes with sterile B. patula cytoplasm were studied, and (iii) the selection of linked genes for hypocotyl colour Rr and one-or two-year growth cycle Bb was carried out. The obtained backcross offspring of BC 3 S B. patula had 95% fertility, 100% CMS-0 type sterility, and sugar content between 19.5% and 21.5%. Recombination in the locus of linked genes of the one-and two-year growth cycles and hypocotyl colour RB rb in hybrids F 1 , B. patula and backcross offspring was detected. At the same time, the oneand two-year growth cycle in seed plants was restored only in the 4th cycle of backcross. Recombinant genotypes with a red hypocotyl and two-year growth cycle BC 3 S B. patula had multi-seed fruits, single or branched stems of seed plants and were chimerical by sterility (CMS-1 and CMS-0 types). The obtained alloplasmic introduced lines containing the cytoplasm of B. patula have economically valuable properties as parent components for the development of new triploid hybrids. The experimental triploid hybrids had root sugar content from 19.5% to 20.5% and dry matter content from 25% to 29%. Alloplasmic lines with the new CMS of B. patula are recommended for sugar beet breeding.
