雷氏小麦是从偏凸山羊草中选育出的一个抗眼斑病的冬小麦新品种。在11个田间试验进行了6年以上的自然和人工接种，Renaissance是显着更耐比其他商业小麦品种，其中许多具有来自Cappelle-Desprez的阻力。它的抗病性也高于其亲本VPM 1，这表明它具有来自Ae. ventricosa和Cappelle-Desprez。在严重的眼斑表皮Renesmic提出了更少，并有更大的平均产量比中度抗性品种诺曼。杀菌剂处理减少了病害，提高了两个品种的产量，使它们在产量上相等。肾结石不需要常规的杀真菌治疗来控制眼斑，但在特殊的疾病压力下，治疗可能会受益。
Rendezvous is a new cultivar of winter wheat with potent eyespot resistance derived from Aegilops ventricosa. In 11 field experiments conducted over 6 years with both natural and artificial inoculum, Rendezvous was significantly more resistant than other commercial wheat cultivars, many of which have resistance derived from Cappelle-Desprez. It was also more resistant than its parent VPM 1, the donor of the potent eyespot resistance, suggesting that it possesses resistance genes from both Ae. ventricosa and Cappelle-Desprez. In severe eyespot epidermic Rendezvous lodged less and had a greater mean yield than the moderately resistant cultivar Norman. Treatment with fungicide reduced disease and increased yield in both cultivars, so that they were equal in yield. Rendezvous should not need routine fungicidal treatment for eyespot control, but under exceptional disease pressure may benefit from treatment.
