Harvest hard red spring wheat

Abstract

Harvest is a hard red spring wheat that meets the end-use quality specifications of the Canada Western Red Spring wheat class. Harvest is adapted to the wheat growing regions of the Canadian prairies based on data from the Central Bread Wheat Cooperative Registration Test conducted in 1998, 1999 and 2000 and grown in Manitoba and Saskatchewan. The overall grain yield of Harvest was significantly higher compared with the check cultivars Neepawa, Roblin, AC Majestic and AC Barrie, but yielded significantly less than the check cultivar McKenzie. Harvest matured similar to McKenzie and Neepawa, 1 d later than Roblin, 1 d earlier than AC Barrie and significantly earlier than AC Majestic. Harvest was significantly shorter than the check cultivars and had the lowest lodging scores. The test weight of Harvest was similar to McKenzie and AC Barrie and significantly higher than Neepawa, Roblin and AC Majestic. Harvest demonstrated moderate resistance to leaf rust and loose smut and very good resistance to stem rust. Resistance to common bunt was fair, similar to Neepawa and AC Barrie. Resistance to Fusarium head blight was similar to the susceptible check Roblin and poorer than the other checks. Harvest had very good preharvest sprouting resistance with lower sprouting scores than the best check in 2 of 3 years of testing, and it maintained its falling numbers after natural or artificial weathering of spikes. End-use quality tests indicated that Harvest was within the range of the checks for most end-use quality traits.
