Development of novel tools to increase wheat grain yield under normal and abiotic stress conditions

有必要开发新的和修订的农学管理工具，以匹配目前在阿尔伯塔种植的硬红春小麦品种的遗传能力，并帮助指导未来的育种工作，以最大限度地提高受基因型x环境x管理因素影响的产量潜力。该项目的总体目标是进一步开发植物生长调节剂类生长素的使用，作为在非胁迫和非生物胁迫条件下提高小麦产量的工具。具体地说，这项研究将为小麦生长素反应性的基本因素提供更详细的了解。通过确定导致小麦生长素反应增加的性状（相对于产量增加），以及表征这些性状如何受到非生物胁迫的影响，我们可以为生产者提高小麦产量提供新的选择。在实践中，如果生产者知道哪些品种对生长素有反应，那么他们就可以针对这些品种使用这种增产促进剂，从而提高其经营的盈利能力。

There is a need to develop new and revised agronomic management tools to match the genetic abilities of the Hard Red Spring wheat cultivars which are currently grown in Alberta and help direct future breeding efforts to maximize yield potential which is influenced by genotype x environment x management factors. The overall objective of this project is to further develop the use of the plant growth regulator class, auxins, as a tool to increase wheat grain yield grown under non-stress and abiotic stress conditions. Specifically, the proposed research will provide a more detailed understanding of the fundamental factors associated with auxin responsiveness in wheat. By determining the traits that lead to increased auxin response (with respect to increasing yield) in wheat, and characterizing how these traits are affected by abiotic stress we can provide a novel option to producers for increasing wheat grain yield. In practice, if producers know which cultivars are auxin responsive, then they can target the use of this yield enhancing promoter to these cultivars and improve the profitability of their operation.
