Barley Breeding

AC Stephen is a six-rowed spring feed barley (Hordeum vulgare L.) cultivar developed by the Eastern Canada Barley Breeding Group, Agriculture Canada, and is adapted to Eastern Canada. It was selected from an OAC Kippen/Léger cross. AC Stephen has high yield, good test weight and is resistant to powdery mildew (Erysiphe graminis DC. ex Merat. f. sp. hordei Em. Marchal). Key words: Hordeum vulgare L., six-rowed barley, feed barley, high yield, powdery mildew

Representative Samples

The response of barley composite cross XLII to selection for resistance to powdery mildew was evaluated. Representative samples from eight cycles of recurrent selection were inoculated with two isolates of Erysiphe graminis f.sp. hordei. Frequencies of resistant plants were determined for each cycle. The resistance in composite cross XLII increased with selection. Increased selection pressure in 1986 resulted in a more rapid increase in resistance than in previous years. Multiple alleles occurring in the Ml-a locus did not seem to have a negative effect on the accumulation of resistance in composite cross XLII. Key words: Hordeum vulgare, barley, Erysiphe graminis f.sp. hordei, powdery mildew, response to selection, recurrent selection.
