Virden is a six-row feed barley (Hordeum vulgare L.) developed at the Agriculture Canada Research Station, Brandon, Manitoba, and is adapted to the western Canadian prairies. This cultivar is late maturing, strong strawed, mid-height to tall, with large, yellow-aleuroned kernels. Virden is resistant to common root rot and stem rust, and is moderately resistant to net blotch, false loose and covered smuts. There is an average 4% increase in yield when compared to Heartland, for all of western Canada, and an average 5 and 8% increase in yield when compared to Heartland and Bedford, respectively, for Manitoba.Key words: Barley (feed) cultivar, Hordeum vulgare

The effects of potassium chloride (KCl) fertilization on common root rot severity (CRR, incited primarily by Cochliobulus sativus), chemical composition of plant tissue, and the grain yield of two barley cultivars (Hordeum vulgare L.) were studied at three locations in northern North Dakota in 1984. KCl was applied at 0, 46 and 188 kg KCl ha−1. Barley cultivars sown were Morex and Azure, with the former being the more susceptible to CRR at all sites. All sites tested ’’high’’ in available soil potassium (greater than 500 kg ha−1). Fertilization with KCl significantly reduced CRR severity of both cultivars at all sites. KCl fertilization dramatically decreased nitrate concentrations and increased chloride concentrations in the plant tissues of both cultivars. Morex accumulated more tissue nitrate than Azure at all levels of KCl fertilization. Thus, increased nitrate concentrations of the plant tissue were correlated with increased CRR severity on both cultivars. Grain yields were significantly increased by KCl fertilization at one site. Increased residual soil chloride was present after harvest at those plots receiving the high rate of KCl. The role of plant nitrate in CRR severity deserves more attention.Key words: Root rot (common), barley, fertilization (chloride), chloride-nitrate interaction, Cochliobulus sativus, Hordeum vulgare L.

Sunray, a spring triticale (×Triticosecale Wittmack) cultivar, is adapted to the Canadian prairies and represents an improvement in ergot resistance for Canadian triticale. Sunray is resistant to the prevalent races of leaf rust, stem rust, common bunt and common root rot and is moderately resistant to grain sprouting. Sunray is short-statured with excellent lodging resistance and grain yield; grain volume test weight and seed mass were similar to the check cultivars. Sunray matures 2 d earlier than Pronghorn and AC Certa, and similar to AC Ultima. Sunray is eligible for the grades of Canada Triticale.

Kernel colour is an important marketing trait for both malting and feed barleys. Therefore a study was initiated to investigate the kernel colour of 75 Canadian barley (Hordeum vulgare L.) cultivars at three locations (Charlottetown, Ottawa and Bentley) across Canada in 1991 and 1992. Kernel colour was measured by an Instrumar Colormet Spectrocolorimeter. Kernel colour was found to be brighter at the two locations in eastern Canada (Charlottetown and Ottawa) than at the location in western Canada (Bentley). Two-row cultivars on average were more discoloured than six-row cultivars; eastern two-row were more discoloured than western two-row. Covered barleys were less discoloured than hulless barleys in five of the six environments, but covered barleys at Bentley in 1992 were more discoloured than hulless barleys. Kernel discolouration appeared to be associated with susceptibility to net blotch for six-row cultivars. More studies are needed on kernel discolouration of barley.

AAC Vitality is a six-row spring feed barley (Hordeum vulgare L.) cultivar developed by the Eastern Cereal and Oilseed Research Centre, Agriculture and Agri-Food Canada. AAC Vitality had high grain yield, good resistance to lodging, and good resistance to straw break. It was late in heading and maturity. Its seed color was bright. AAC Vitality was moderately resistant to net blotch and spot blotch. AAC Vitality performs well in Ontario.

AC Copia, a cultivar of spring triticale (X Triticosecale Wittmack), was developed at the Research Station, Research Branch, Agriculture and Agri-Food Canada, Swift Current, SK. It is widely adapted to the Prairie Provinces of Western Canada. AC Copia represents an improvement in test weight over other currently available Canadian cultivars of triticale. It is very resistant to the prevalent races of leaf rust, stem rust and common bunt, and moderately resistant to common root rot.

Selection Of

Field trials distributed throughout the Prairie Provinces in western Canada indicate that any location is suitable for the selection of wheats for resistance to common root rot caused by Cochliobolus sativus, providing the level of infection is sufficiently high. Wheat lines originally selected for resistance were consistently resistant in field tests at all locations. Three of four lines were significantly more resistant than Thatcher, one of the most resistant of the commercial varieties. A high consistency in the reaction of lines selected for susceptibility also was evident in the tests. A significant interaction in the analysis of variance found between wheat lines and locations might be interpreted as indicating the occurrence of differentially pathogenic races of the fungus. Other explanations, however, are offered for this interaction effect.

The effect of varying interplant competition on common root rot and yield was examined in barley over a 4-yr period. One experiment studied the effects of thinning. Other tests with a constant level of interplant competition examined the effects of interplanted root-rot-resistant barley or oat cultivars on the root rot reaction and yield of susceptible barley cultivars. Increasing interplant spacing by thinning reduced root rot significantly in Gateway and Bonanza barley in 1 out of 4 years, but yield was increased significantly only in Gateway in 2 out of 4 years. Yield reduction due to root rot was significantly less in 1 out of 2 years when the distance between Gateway plants was increased due to the interplanting of oats. The lack of a consistent reduction in root rot or yield loss by reducing plant competition or interplanting with moderately resistant barley or oats precludes use of lower seeding rates or mixed crops as an economic method of reducing root rot.Key words: Interplant competition, common root rot, barley

More than 2000 wheat collection samples were studied for seedling resistance to 4 diseases. Noncoincidence of results obtained after inoculation of leaf segments placed on water solution of benzimidazole (60 ppm) and intact plants was found for 3 foliar diseases (leaf rust – Puccinia recondita, dark brown leaf spot blotch – Bipolaris sorokiniana and septoria glume blotch – Septoria nodorum). Sixty-three entries were resistant to leaf rust; 26 of them have gene for resistance Lr26 (non-effective under field condition), 25 – gene Lr24, 4 – gene Lr19, 8 – gene Lr9 and 2 – gene Lr41. Samples 181-5, Fielder, Butte 66, Raj 1972 and Soisson were moderately resistant to spot blotch; 181-5 – to common root rot and Moking and MN 81330 – to glume blotch. Very high level of partial resistance to 3 diseases was found in late generations of somaclonal lines of weakly and moderately resistant initial genotypes: to leaf rust in lines of cv. Spica, to leaf spot blotch – in lines of 181-5, to common root rot – in that of 181-5 and cv. Vera; moderate resistance to glume blotch was identified in lines of cv. Spica.
