Investigating novel quantitative genetics approaches in barley genetics

为了满足人类的需求，粮食产量必须增加。大麦是加拿大农业的主要作物。Cerela、安大略省农业部和圭尔夫大学之间的这个合作项目的目标有三个。首先，我们将通过将新鉴定的抗病高产大麦品系与现有品种杂交，并从数千个后代中选择最好的品系来开发新的大麦种质。其次，我们将评估育种、气候变化和管理对大麦产量的长期影响。最后，我们将利用DNA信息和先进的统计方法对大麦品种的表现进行估计，并确定影响重要性状的关键基因。这项工作具有经济、环境和社会影响。这项工作将产生改良的大麦种质，估计随着时间的推移遗传和环境变化如何影响这种作物，并开发加速育种进程的方法。

To meet human demands, grain production must increase. Barley is a key crop for Canadian agriculture. The goals of this collaborative project between Cerela, the Ontario Ministry of Agriculture, and the University of Guelph are three-fold. First, we will develop new barley germplasm by crossing newly identified disease resistant and high yielding barley lines with established cultivars and selecting the best lines from 1000s of progeny. Second, we will evaluate the long-term impacts of breeding, climate change, and management on barley yields. Finally, we will develop estimates of barley cultivars' performance using DNA information and advanced statistical methodologies and identify key genes that contribute to important traits. This work has economic, environmental and social impacts. The work will generate improved barley germplasm, estimate how genetic and environmental changes have affected this crop over time, and develop methods to accelerate breeding progress.
