“…It can be suggested that H. marinum chromosome 7H m carries a red coleoptile allele at the orthologous locus Rc-H m 1. This gives additional support to the conclusion made earlier by Pershina et al (2009) that H. marinum chromosome 7H m possesses an ability to compensate for absence of chromosome 7D of common wheat. Because it, as well as the Aegilops Rc-S1 alleles originating from Ae.…”

“…The aim of the current study was to find potential sources of 'strong' Rc alleles conferring very high levels of anthocyanin production and to study the effect of genetic background on Rc expression. Wheat genetic stock collections, intraspecific wheat (Kuspira and Unrau 1958) and wheat-alien (Silkova et al 2006;Troubacheeva et al 2008;Pershina et al 2009) chromosome substitution lines and wheat-alien chromosome addition lines (Driscoll and Sears 1971;Friebe et al 1993Friebe et al , 1995Friebe et al , 2000 are good models to investigate this issue, as they can be used in comparative analyses of gene expression in different genetic backgrounds. Furthermore, since common wheat relatives can be a potential source of useful genes, analysis of wheat-alien lines carrying Rc genes originating from different species may result in the discovery of more desirable alleles.…”

Anthocyanin accumulation in vegetative organs has a relationship to stress resistance in plants. In wheat, ability to accumulate anthocyanins in the coleoptile is inherited and controlled by the Rc (red coleoptile) genes. The aim of the current study was to find potential sources of 'strong' Rc alleles conferring very high levels of anthocyanin production and to study the effect of genetic background on Rc expression. We measured the relative anthocyanin content (OD530) in the coleoptile of different wheat and wheat-alien genetic stocks and accessions to find potential sources of 'strong' Rc alleles conferring very high levels of anthocyanin production. The OD530 values varied from 0.514 to 3.311 in genotypes having red coleoptiles. The highest anthocyanin content was detected in coleoptiles of four Triticum dicoccoides accessions originating from Israel and the Russian T. aestivum cultivar 'Novosibirskaya 67', suggesting that their Rc alleles can be used to increase anthocyanin content in the coleoptile of wheat cultivars. It is also suggested that rye Rc alleles, such as that of Russian cultivar 'Selenga', can be used to increase anthocyanin content in triticale seedlings.

“…The salt tolerance of the wheat-H. marinum amphiploid was intermediate to that of its parents (Islam et al 2007). Alloplasmic wheat-barley substitution and addition lines were produced by Pershina et al (2009) from H. marinum ssp. gussoneanum Huds.…”

Wheat–barley hybridization: the last 40 years

2013

View full text Add to dashboard Cite

Several useful alien gene transfers have been reported from related species into wheat (Triticum aestivum), but very few publications have dealt with the development of wheat/barley (Hordeum vulgare) introgression lines. An overview is given here of wheat 9 barley hybridization over the last forty years, including the development of wheat 9 barley hybrids, and of addition and translocation lines with various barley cultivars. A short summary is also given of the wheat 9 barley hybrids produced with other Hordeum species. The meiotic pairing behaviour of wheat 9 barley hybrids is presented, with special regard to the detection of wheatbarley homoeologous pairing using the molecular cytogenetic technique GISH. The effect of in vitro multiplication on the genome composition of intergeneric hybrids is discussed, and the production and characterization of the latest wheat/barley translocation lines are presented. An overview of the agronomical traits (b-glucan content, earliness, salt tolerance, sprouting resistance, etc.) of the newly developed introgression lines is given. The exploitation and possible use of wheat/barley introgression lines for the most up-to-date molecular genetic studies (transcriptome analysis, sequencing of flow-sorted chromosomes) are also discussed.

“…For instance, in nearly isogenic lines a significant negative effect of Gpc B1 (from T. dicoccoides) on MTG of grains and test weight of grains [87,88] was recorded. Interestingly, in alloplasmatic line with substitution of chromosomes 1H mar (1B), 5H mar (5D), 7H mar (7D) and alloplasmatic ditelosomic supplemented line 7HL mar , the protein content in grain is higher than in the culti var of common wheat Pyrotrix 28, which Pershina et al [89] explain by the influence of chromosomes of wild barley H. marinum subsp. gussoneanum.…”

Studies on identification and localization of quantitative traits for grain protein content (QGpc loci) on chromosomes in Triticum aestivum and Triticum durum are reviewed. Association of QGpc with vari ous traits of morphology, physiology, adaptation and tolerance to abiotic and biotic stress is shown. Genetic and environmental QGpc contexts that should be taken into account when using molecular markers in breed ing for the grain protein content are considered.
