Meloidogyne paranaensis is responsible for considerable losses in coffee production. Because of the distribution of this species in the main Coffea arabica producing regions, there is a need for management practices to ensure the sustainability of coffee production. In this work, we evaluated the agronomic performance of resistant clones of the Conilon coffee cultivar Vitoria Incaper 8142 in areas infested by M. paranaensis in the west region of Minas Gerais, Brazil. Clones 2V, 3V, and 6V presented the lowest number of nematodes per gram of roots and were considered resistant to M. paranaensis. All other clones were considered tolerant to this nematode, and one had good vegetative growth but allowed nematode reproduction. Clones of Vitoria Incaper 8142 of C. canephora represent an alternative to coffee production in areas infested by M. paranaensis including areas traditionally cultivated with C. arabica.

Conilon咖啡品种Vitoria Incaper 8142在田间条件下对巴拉那根结线虫的抗性

巴拉那根结线虫造成咖啡生产的巨大损失。由于该物种分布于主要阿拉比卡咖啡产区，需要管理实践来确保咖啡生产的可持续性。在这项工作中，我们评估了 Conilon 咖啡品种 Vitoria Incaper 8142 的抗性克隆在受感染的地区的农艺性能。M. paranaensis位于巴西米纳斯吉拉斯州西部。克隆 2V、3V 和 6V 的每克根中线虫数量最少，被认为对M. paranaensis. 所有其他克隆都被认为对这种线虫具有耐受性，其中一个具有良好的营养生长，但允许线虫繁殖。Vitoria Incaper 8142 的克隆C. canephora代表在受感染的地区替代咖啡生产M. paranaensis包括传统上种植的地区阿拉比卡咖啡豆.
