“…They were also the highest yielders on the Cu-ameliorated soil, with a relative grain production up to 1.5 times higher than Park. These results also agree well with the findings of studies conducted on 5RL/SBS, 5RL/4AS and 4BL/5RL near-isogenic lines, and their non-translocation wheat parents, which indicated that the lines with 5RL wheat-rye chromatin were Cu-efficient (Graham et al, , 1987Podlesak et al, 1990;Schlegel et al, 1991). From the current study, it is evident that the Cu-efficiency gene(s) on the chromosome 5RL offers potential for exploitation by crossing to otherwise well-adapted, but Cu-inefficient Kenyan or Canadian cultivars.…”

“…This suggestion differed from the earlier report of Graham (1984), which indicated that 5RL/4AS and 5RL/5BS wheat-rye translocation lines had higher Cu concentrations in the leaf tissues, and higher Cu uptake from Cu-deficient soils. Schlegel et al (1991) confirmed a high Cu-efficiency for grain yield in the winter wheat 'Viking' with 4BL/5RL, by growing the cultivar on Cu-deficient soil. This locus has subsequently been mapped in rye (Schlegel et al, 1993).…”

A greenhouse study was conducted to determine the Cu-efficiency of 5A/5RL wheat-rye translocation lines and nine wheat genotypes grown in a Cu-deficient orthic dark grey chernozemic soil. The soil used was characterized by pH 5.4 and 0.48 #g Cu g-l soil (DTPA), and was obtained from a known Cu-deficient site at Stony Plain, Central Alberta. Twelve genotypes (three 5AJ5RL wheat-rye translocation lines and nine wheat cultivars) and two Cu treatments (soil amended with 145 #g Cu kg -l soil, and non-amended) were used. The efficiency for Cu use was evaluated for grain yield and yield components. 5A/5RL wheat-rye translocation lines individually and as a group showed significantly (p<0.05) higher grain yield both in +Cu and -Cu treatments compared to wheat genotypes without the wheat-rye chromosome translocation. 5AJ5RL wheat-rye translocation lines demonstrated Cu-efficiency ranging from 70-127% for grain yield. Only two wheat cultivars (Kenya Leopard and Columbus) showed comparable efficiency (70 and 76% respectively). Wheat cultivars Kwale, Kenya Tausi, Roblin, Katepwa, Park, Oslo and Biggar showed low Cu-efficiency (10-36%). The study confirms that the 5AJ5RL wheat-rye translocation confers useful levels of Cu-efficiency to wheat, that can be used as an additional source of variability in breeding programs.

“…This trait on chromosome 4B is inherited in a simple Mendelian dominant manner (Driscoll and Sears 1965) and the "hairy peduncle" has been mapped to a region about 45 cM from the centromere on the long arm of chromosome 5 (5RL) (Schlegel et al 1993). Graham (1984) confirmed earlier reports from Merker (1975), Graham (1978), and Harry and Graham (1981) that a copper efficiency character was also located on 5RL and Schlegel et al (1991) mapped the copper efficiency gene(s) (Ce) to the 5RL2.3 band using Giemsa C banding and isoenzyme analysis. Cereals such as wheat and barley are intolerant of low levels of available copper, such as those found in many cereal-growing districts, but cereal rye is known to be copper efficient and can grow well on impoverished soils.…”

The physical length of the rye segment of a 4BS.4BL-5RL translocation derived from the Cornell Wheat Selection 82a1-2-4-7 in a Triticum aestivum 'Chinese Spring' background was measured using genomic in situ hybridization (GISH) and found to be 16% of the long arm. The size of this translocation was similar to previously published GISH measurements of another 4BS.4BL-5RL translocation in a Triticum aestivum 'Viking' wheat background. Molecular maps of both 4BS.4BL-5RL translocations for 2 different wheat backgrounds were developed using RFLP analysis. The locations of the translocation breakpoints of the 2 4BS.4BL-5RL translocations were similar even though they arose in different populations. This suggests a unique property of the region at or near the translocation breakpoint that could be associated with their similarity and spontaneous formation. These segments of rye chromosome 5 also contain a gene for copper efficiency that improves the wheat's ability to cope with low-copper soils. Genetic markers in these maps can also be used to screen for copper efficiency in bread wheat lines derived from the Cornell Wheat Selection 82a1 2-4-7.

“…In several alien substitution lines of common wheat, rye chromosome 5R was substituted for chromosomes of wheat homologous group 5 (Sears 1967, Bielig & Driscoll, 1970. Other lines contained wheat-rye translocations for chromosome 5RL (Graham et al, 1987;Schlegel et al, 1991;Vahl et al, 2001).…”

Effect of alien 5R(5A) chromosome substitution on ear-emergence time and winter hardiness in wheat-rye substitution lines

et al. 2006

Ear emergence time and response to vernalization were investigated in 12 alien substitution lines in which a pair of chromosomes 5A of recipient spring wheat cultivars was replaced by a pair of chromosomes 5R of Siberian spring rye 'Onokhoiskaya'. The recipients were 12 spring cultivars of common wheat, each carrying different Vrn genes. Spring rye 'Onokhoiskaya' had the Sp1 (now called Vrn-R1) gene for spring growth habit located on chromosome 5R, but its expression was weaker. The Vrn-R1 gene had no effect on growth habit, ear emergence time and response to vernalization in wheat-rye substitution lines. Ears emerged significantly later in the 5R(5A) alien substitution lines than in the recipient wheat cultivars with the Vrn-A1/Vrn-B1/vrn-D1 or Vrn-A1/vrn-B1/Vrn-D1 genotypes. No difference in ear emergence time was found between most of the 5R(5A) alien substitution lines and the cultivars carrying the recessive vrn-A1 gene. The presence of the Vrn2a and Vrn2b alleles at the Vrn2 (now called Vrn-B1) locus located on wheat chromosome 5B was confirmed.The replacement of chromosome 5A by chromosome 5R in wheat cultivars 'Rang' and 'Mironovskaya Krupnozernaya', which carries the single dominant T.T. Efremova ( ) · O.I. Maystrenko · V.S. Arbuzova · L.I. Laikova · G.M. Panina · O.M. Popova · O.V.gene Vrn-A1, converted them to winter growth habit. In field studies near Novosibirsk the winter hardiness of 5R(5A) wheat-rye substitution lines of 'Rang' and 'Mironovskaya Krupnozernaya' was increased by 20-47% and 27-34%, respectively, over the recurrent parents.
