Wheat is grown on about 10 million ha in the tropical highlands and lowlands of the world, where it is an important food source. Many farmers in these areas work under subsistence conditions. Wheat diseases in tropical regions can be severe and require significant efforts to control. For economic and environmental reasons, host plant resistance is the most appropriate and sustainable disease control method. We describe highland and lowland tropical wheat regions and discuss CIMMYT's breeding strategies, philosophies, and progress in developing resistance to the major diseases such as rusts, foliar blights, fusarium scab, BYD, and spot blotch. Additionally, we review the role of national wheat research programs and beneficial spillovers of our combined breeding efforts to other wheat production areas of the world.

为热带高地和低地培育抗病小麦。

小麦生长在世界热带高地和低地上，约一千万公顷，是重要的食物来源。这些地区的许多农民在生存条件下工作。热带地区的小麦疾病可能很严重，需要大力控制。由于经济和环境原因，寄主植物抗性是最合适和可持续的疾病控制方法。我们描述了高地和低地热带小麦地区，并讨论了CIMMYT的育种策略，理念以及对诸如锈病，叶枯病，镰刀赤霉病，BYD和斑点病等主要疾病产生抗性的进展。此外，我们回顾了国家小麦研究计划的作用以及我们联合育种工作对世界其他小麦产区的有益溢出效应。
