Climate change is already unfolding on Canada's prairies. Canada is a top global exporter of pea, a crop mainly grown in western Canada. Pea crops on the prairies yield poorly and inconsistently in warm summers because they experience heat stress in the growing season. Yield instability and reductions negatively affect the pea industry and exports. Pea cultivars (varieties) tested in the last decade have shorter crop life cycles and likely more aborted flowers and pods in warm or dry summers, resulting in low yield. Our pea cultivars need to be more heat tolerant. Surprisingly, the pea crop is still waiting to be improved for a range of stresses.

气候变化已经在加拿大的大草原上展开。加拿大是全球最大的豌豆出口国，这种作物主要种植在加拿大西部。大草原上的豌豆作物在温暖的夏天产量很低，而且不稳定，因为它们在生长季节会经历热胁迫。产量不稳定和减产对豌豆产业和出口产生不利影响。在过去十年中测试的豌豆品种（品种）作物生命周期较短，在温暖或干燥的夏季可能会有更多的花和豆荚败育，导致产量低。我们的豌豆品种需要更耐热。令人惊讶的是，豌豆作物仍在等待一系列压力的改善。
