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艺管理工具，以匹配目前在艾伯塔省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努力，以最大限度地提高受基因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发展植物生长调节剂类生长素的使用，作为提高在非胁迫和非生物胁迫条件下生长的小麦籽粒产量的工具。具体地说，拟议的研究将提供更详细的了解与小麦生长素反应相关的基本因素。通过确定导致小麦生长素反应增强(与增产有关)的性状，并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供提高小麦籽粒产量的新选择。在实践中，如果生产者知道哪些品种对生长素有反应，那么他们就可以有针对性地使用这种增产促进剂来提高这些品种的盈利能力。

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.
