“…Both purple-and blue-grain markers could also be used in studies to measure the degree of natural cross pollination, and of gamete transmission, histological observations and pigment characterization (Bolton, 1968;Griffin, 1987;Whelan, 1989;Keppenne & Baenziger, 1990). Knott (1958) and Whelan (1989) stated that it was difficult to establish levels of open pollination because grains with one allele for blue pigment were difficult to separate from those with no blue allele.…”

“…However, the erratic expression of pigmentation in F1 grains and especially the number of years involved to produce the blue-and purple-grained hybrid components would make the use of these characters very conservative. Keppenne & Baenziger (1990) suggested that this character could be used in separating doubled haploids obtained after anther culture. Assuming that the parental plant was heterozygous the doubled haploid plants should have either deep blue aleurone (genotype BaBaBa) or non-blue seeds.…”

“…Because this may cause male sterility leading to open pollination and hence further variation care should be taken to ensure selfing during any study. Suneson (1964) and Piech & Evans (1979) used the gene symbol B1 (blue), Kuspira et al (1989) coded the gene for blue grain colour Bk (blue kernel), whereas Keppenne & Baenziger (1990), in accordance with Dr. R.A. McIntosh, co-ordinator of gene symbols for wheat, adopted Ba (blue aleurone). The Bl and Ba genes derive from Agropyron species.…”

Wheats with purple and blue grains: a review

1991

View full text Add to dashboard Cite

In addition to white and red grains, wheats with purple and blue grains may occur. Purple grain colour is caused by anthocyanins in the pericarp whereas blue colour is caused by anthocyanins in the aleurone layer. Purple grains occur in tetraploid wheats from Ethiopia, and in one bread wheat accession apparently native to China.Although the use of the purple and blue grain characters as markers has been suggested, their expression is often erratic, especially when heterozygous.No hexaploid wheat with blue grains was described prior to the artificial introgression of genes from diploid wheat and Agropyron species. The number of different sources of blue aleurone gene(s) from Agropyron elongatum is unknown. It is possible that with exchange between researchers the same or related accessions have been used at several research stations. Accessions of diploid wheats are known to possess blue aleurone. The breeding history of a number of purple and blue grained accessions is described. Research should indicate the source species of the gene for blue aleurone of the blue-grained Barevna.Nomenclature: The nomenclature of the species belonging to Agropyron sensu lato (incl. Elytrigia and Thinopyrum) is confusing for the non-specialist. Several nomenclatures are in use. The old Agropyron names will be used in this review, but some synonyms are presented for convenience:Agropyron elongatum (Host) P. Beauv. = Thinopyrum elongatum (Host) D.R. Dewey = Elytrigia pontica (Podp.) Holub; Agropyron glaucum (Desf. ex DC.) Roemer & Schultes = Thinopyrum intermedium (Host) Barkworth & D.R. Dewey; Agropyron intermedium (Host) P. Beauv. = Thinopyrum intermedium (Host) Barkworth & D.R. Dewey = Elytrigia intermedia ssp. barbulata; Agropyron junceum (L.) P. Beauvois = Thinopyrum junceum (L.) L6ve.

“…The blue-grained gene of Th. ponticum was designated Ba1 (Jan et al 1981;Keppenne and Baenziger 1990;Dubcovsky et al 1996; http://www. shigen.nig.ac.jp/wheat/komugi/) and was physically mapped to the region of FL0.71-0.80 on the long arm of chromosome 4Ag using a set of translocations that showed different seed colors (Zheng et al 2006).…”

Blue wheat grain contains different groups of pigments that can be used for making specialty foods or as food colorants. Thinopyrum bessarabicum, a wild relative of wheat, carries a blue-grained gene on chromosome 4J. In this study, we analyzed the mitotic chromosomes of 159 F7 lines derived from the cross between Triticum aestivum cv. Chinese Spring (CS) and a CS-Th. bessarabicum amphiploid by using multi-color fluorescence in situ hybridization, genomic in situ hybridization, and newly developed chromosome 4J-specific DNA markers. Intact chromosome 4J and various 4J chromosomal segments were identified in the 159 lines. The blue-grained gene of Th. bessarabicum was physically localized to the region between the centromere and FL0.52 on chromosome arm 4JL. The chromosomal location of this gene differed from the location of previously reported blue-grained genes. In addition, a strong dosage effect was observed with this gene. These results suggest that the blue-grained gene in Th. bessarabicum represents a novel gene locus for blue aleurone, designated BaThb. The wheat lines and 4J chromosome-specific molecular markers developed in this study will facilitate the introgression and utilization of BaThb for wheat nutritional quality improvement.

Martinek P., Škorpík M., Chrpová J., Fučík P., Schweiger J. (2013) Breeding wheat with blue grain was conducted at the Crop Research Institute in Prague. Initial donor material came from the legacy of Erich von Tschermak-Seysenegg. Long-term crosses with a series of winter wheat varieties were made with the aim of transferring blue grain colour into cultivated varieties. The prospective material was later handed over to Agrotest Fyto, Ltd., Kroměříž, where line no. 6 was selected from the population RU 440. At the end of 2011, the new winter wheat variety Skorpion with blue grain was registered in Austria. It is intended for special use in the food industry. The anthocyanins which it contains are considered to offer health benefits due to their antioxidant effects.
