大多数硬粒小麦（Triticum durum）品种由于其霜冻敏感性而仅具有较低的抗寒性。因此，在北美和中欧，硬粒小麦通常在春季播种，以避开当地的冬季条件。然而，如果有耐霜冻性增强的硬质合金品种，可以在秋季播种，这些地区的硬质合金产量潜力可以得到更好的开发。一个因素限制育种提高耐霜冻性的变化，在发生霜冻胁迫跨年。“Weihenstephaner Auswinterungsanlage”是一种半受控测试，将植物暴露在所有天气条件下。半受控试验中的可移动玻璃盖可防止植物被雪覆盖，起到防冻保护的作用。在这项研究中，基于这种半控制试验的不同耐霜冻评分进行了评估，并与田间耐霜冻数据进行了比较。我们的研究结果说明了潜在的“Weihenstephaner Auswinterungsanlage”作为一个间接的选择工具，耐霜冻硬质合金育种计划，特别是当常规的耐霜冻数据从外地不可用。
Most durum wheat (Triticum durum) varieties possess only low winter hardiness due to their frost susceptibility. In North America and Central Europe, durum wheat is therefore typically sown in spring to circumvent the local winter conditions. However, the yield potential of durum in these regions could be much better exploited if durum varieties with increased frost tolerance were available, which could be sown in autumn. A factor limiting breeding for increased frost tolerance is the variation in the occurrence of frost stress across years. The ‘Weihenstephaner Auswinterungsanlage’ is a semi‐controlled test that exposes the plants to all weather conditions. Snow coverage of the plants, serving as frost protection, is prevented by the movable glass lid of the semi‐controlled test. In this study, different scorings for frost tolerance based on this semi‐controlled test were evaluated and compared with frost tolerance data in the field. Our results illustrate the potential of the ‘Weihenstephaner Auswinterungsanlage’ as an indirect selection tool for frost tolerance in durum breeding programmes, especially when regular frost tolerance data from the field are not available.
