The influence of inoculum concentration on the reaction induced in species and cultivars of commercial cereals by two isolates of ergot (Claviceps purpurea (Fr.) Tul.) was investigated. Differences were observed among and within species with respect to each of the three components of the disease reaction, i.e., frequency of sclerotia, size of sclerotia, and amount of honeydew produced. Spring wheat (Triticum aestivum L.) was less susceptible than the other cereal species. Significantly fewer sclerotia were produced on spring wheat except at high and low inoculum concentrations and the sclerotia were smaller and the honeydew less abundant. Inoculation of selected cultivars within each of the cereal species showed that only cultivars of spring wheat and durum wheat (T. durum Desf.) differed in the expression of the disease reaction. The spring wheat cultivar Kenya Farmer, and durum wheat cultivar Carleton were less susceptible than the commercial cultivars. Inoculum concentration affected sclerotial frequency in the species and cultivars tested but did not affect sclerotial size and honeydew development. The two isolates used in this study differed in their ability to induce sclerotia and also affected sclerotia size and honeydew production.

Moderately Resistant

Glenavon hard red extra strong spring wheat (Triticum aestivum L.) is adapted to the Canadian prairies. It combines 2 to 6% higher grain yield with improved test weight compared to AC Corinne, Glenlea and Wildcat. It is resistant to moderately resistant to prevalent races of leaf and stem rust, resistant to loose smut, and of intermediate resistance to common bunt. Glenavon is eligible for all grades of the Canada Western Extra Strong wheat class.

AC Elsa, hard red spring wheat (Triticum aestivum L.), is adapted to the Canadian Prairies. It combines high grain yield with high grain protein concentration in a short strawed background. It has improved resistance to leaf spots compared with the check cultivars, and resistance to prevalent races of leaf rust, stem rust, loose smut, and common bunt. AC Elsa is eligible for grades of Canada Western Red Spring wheat. Key words: Triticum aestivum L., red spring wheat, cultivar description, yield, protein, disease resistance

Abstract Yield losses caused by pests, including aphids, can be substantial in cereals. Breeding for resistance against aphids is therefore desirable for enhancing the economic and environmental sustainability of cereal production. The aim of our study was to reveal the degree of antibiosis against Metopolophium dirhodum (Walker) (Homoptera: Aphididae), in four cultivars of spring wheat, Triticum aestivum L. (‘Alicia’, ‘Odeta’, ‘Libertina’, ‘Astrid’), and two cultivars of emmer, Triticum turgidum ssp. dicoccum (Schrank ex Schübler) Thell. (‘Rudico’, ‘Tapiruz’) (both Poales: Poaceae) under controlled laboratory conditions. Using age-stage, two-sex life table, we quantified responses of M. dirhodum to each cultivar and to project population growth. The spring wheat and emmer cultivars varied in their suitability to M. dirhodum. The cultivar most susceptible to M. dirhodum was the emmer cultivar ‘Rudico’; the projected population size of M. dirhodum on this cultivar was one order of magnitude larger than those on other cultivars. The most resistant cultivar was the spring wheat cultivar ‘Libertina’. Since emmer is commonly used as a gene source for breeding T. aestivum, we advocate that care be taken to avoid the transmission of genes responsible for suitability to aphids from emmer to T. aestivum.

Solubility characteristics and amino acid composition of the endosperm proteins of one line of Triticale, its durum wheat and rye parent cultivars, and one cultivar of hard red spring wheat were compared. Quantitative distribution of the soluble protein fractions and amino acid compositions showed that the proteins of Triticale are intermediate in these properties between analogous properties of the proteins of its durum wheat and rye parents. The major differences between the hard red spring wheat and the other three species were its lower content of water-soluble proteins and higher content of insoluble or gluten proteins. This appears lo be the main reason for the superior breadmaking quality of the hard red spring wheat cultivar compared with the other species used in this study.
