AC Foremost, red-seeded spring wheat (Triticum aestivum L.), combines high grain yield with resistance to prevalent races of common bunt (caused by Tilletia laevis Kuhn in Rabenh. and T. caries (DC.) Tul. & C. Tul.), and loose smut except T9 (caused by Ustilago tritici (Pers.) Rostr. in a semidwarf, photoperiod insensitive background. AC Foremost has improved pre-harvest sprouting tolerance compared with Biggar, AC Taber, and Genesis; improved resistance to leaf rust (caused by Puccinia recondita Roberg ex Desmaz.) and leaf spots (caused by Septoria spp. and Pyrenophora tritici repentis (Died.) Drechs.) compared with Neepawa and Biggar, and earlier maturity compared with Biggar, AC Taber, and Genesis. AC Foremost is eligible for grades of the Canada Prairie Spring (Red) 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

Helios hard red spring wheat (Triticum aestivum L.) has expressed high grain yield and medium time to maturity. The straw length and strength, volume weight, and seed size were intermediate to the check cultivars. It expressed resistance to prevalent races of stem rust and loose smut, intermediate resistance to common bunt and Fusarium head blight, and moderate susceptibility to leaf rust and leaf spots. It expressed resistance to pre-harvest sprouting and high Hagberg falling number. The end-use suitability of Helios was similar to that of the controls and, therefore, it is eligible for all grades of the Canada Western Red Spring (CWRS) wheat class. Key words: Triticum aestivum L., cultivar description, grain yield, disease resistance, Hagberg falling number

AC Crystal is a red-seeded spring wheat (Triticum aestivum L.). In combining high grain yield and resistance to prevalent races of common bunt in a semidwarf, photoperiod-insensitive background it is similar to AC Taber. It has improvements relative to AC Taber: resistance to prevalent races of loose smut, except race T9, and stronger gluten properties. AC Crystal has improved resistance to leaf spots compared to Neepawa, AC Karma, and AC Foremost. It is eligible for grades of the Canada Prairie Spring (Red) wheat class. Key words: Triticum aestivum L., cultivar description, loose smut resistance, common bunt resistance, high yield, red spring wheat

A pathogen transmitted by the eriophyid mite, Aceria tulipae, infects a number of Gramineae producing symptoms similar to wheat spot mosaic virus (1). An electron microscope study of leaf ultrastructure from systemically infected Zea mays, Hordeum vulgare, and Triticum aestivum showed the presence of ovoid, double membrane bodies (0.1 - 0.2 microns) in the cytoplasm of parenchyma, phloem and epidermis cells (Fig. 1 ).
