Sweetpotato in the Mediterranean is mainly grown in Egypt, Spain, Portugal, and Israel. Yields vary from 34 tons/ha in Israel to 7.8 tons/ha in Portugal. As sweetpotatoes are vegetatively propagated, the differences in yields are probably due to the quality in the propagation material, mainly infection by various viruses. The main viruses affecting sweetpotato in Mediterranean countries are Sweet potato feathery mottle virus potyvirus, Sweet potato sunken vein virus (Sweet potato chlorotic stunt virus) crinivirus, and their combined infection, causing the sweetpotato disease. Eleven other viruses sporadically reported from Mediterranean countries are also reviewed, as well as possible methods for control.
地中海地区的甘薯主要种植在埃及、西班牙、葡萄牙和以色列。产量从以色列的 34 吨/公顷到葡萄牙的 7.8 吨/公顷不等。由于甘薯是通过营养繁殖的，产量的差异可能是由于繁殖材料的质量不同，主要是受到各种病毒的感染。影响地中海国家甘薯的主要病毒有甘薯羽状斑驳病毒马铃薯 Y 病毒科、甘薯陷脉病毒（甘薯黄矮病毒）呼肠孤病毒科，以及它们的复合感染，导致甘薯病害。本文还综述了地中海国家偶尔报道的另外 11 种病毒，以及可能的控制方法。
