Plain language summary

AAC Penhold is a high yielding Canada Prairie Spring Red wheat-market-class cultivar with short strong straw. This variety is higher-yielding and has larger kernels than those it was tested against. It also has resistance to rust and common bunt, and moderate resistance to stem rust and Fusarium head blight. This variety provides another resource from which producers can choose when planting red spring wheat.


AAC Penhold, an awned hard red spring wheat (Triticum aestivum L.) cultivar, yielded significantly more grain than check cultivar 5700PR while maturing 2 d earlier and was 7.5 cm shorter in stature. The seed size was significantly larger than 5700PR and 5701PR, with a test weight significantly heavier than both checks. AAC Penhold expressed resistance to prevalent races of leaf rust and common bunt and moderate resistance to Fusarium head blight and stem rust. AAC Penhold had higher grain and flour protein than the checks and improved Hagberg falling number, amylograph viscosity, and water absorption. AAC Penhold is eligible for grades of the Canada Prairie Spring Red wheat market class.
