沙氏囊线虫是甜菜栽培中最重要的生物胁迫因子。线虫可以通过轮作、用杀线虫剂熏蒸或种植抗性作物来控制。然而，由于杀线虫剂对环境的毒性影响，它们已不再被允许使用，作物轮作制度在农艺学上往往是不切实际的，而且迄今为止甜菜种质中还没有遗传抗性。因此，在过去几年中，已经应用了其他控制线虫的策略。例如，鉴定了野生甜菜品种的遗传抗性并将其转移到优良育种材料中。今天，几种耐线虫的甜菜品种已经上市。此外，基于基因工程的不同方法已被开发用于提高植物线虫的抗性。然而，甜菜种植中线虫的有效控制仍然是一个巨大的挑战。
The cyst nematodeHeterodera schachtiibelongs to the most important biotic stress factors in sugar beet cultivation. Nematodes can be controlled by crop rotation, by fumigation with nematicides or by growing resistant crops. However, nematicides are no longer admitted to be used because of their toxic environmental impacts, the crop rotation system is often agronomically impracticable and the genetic resistance is so far not available in sugar beet germplasms. Thus, alternative strategies for nematode control have been applied in the past years. For instance, genetic resistance from wild beet species were identified and transferred into the elite breeding materials. Today several nematode tolerant varieties of sugar beet are commercially available. In addition, different approaches based on genetic engineering have been developed to improve plant nematode resistance. Nevertheless, an effective control of nematodes in sugar beet cultivation still remains a great challenge.
