Upland cotton (Gossypium hirsutum L.) is susceptible to damage by the root-knot and the reniform nematodes, causing yield losses greater than 4% annually in the United States. In addition, these nematodes are synergistic with seeding disease and root rot pathogens that exacerbate diseases and subsequent yield losses. Production practices to minimize nematode damage include crop rotation and nematicides, but these techniques need to be repeated and are expensive. The use of resistant cultivars is deemed the most effective and economical approach for managing nematodes in cotton. Here, we describe the genomes of two nematode-resistant lines of cotton, BARBREN-713 and BAR 32-30. These genomes may expedite the development of DNA markers that can be used to efficiently introduce nematode resistance into commercially valuable Upland lines.
陆地棉（Gossypium hirsutum L.）易受根结线虫和肾形线虫的侵害，在美国每年造成超过 4%的产量损失。此外，这些线虫与引发病害和随后减产的种子病害和根腐病病原体具有协同作用。减少线虫损害的生产实践包括轮作和杀线虫剂，但这些技术需要重复使用且成本高昂。使用抗性品种被认为是管理棉花线虫最有效和经济的方法。在这里，我们描述了两种抗线虫棉花品系 BARBREN-713 和 BAR 32-30 的基因组。这些基因组可能会加速开发 DNA 标记，这些标记可用于有效地将线虫抗性引入具有商业价值的陆地棉品系中。
