近年来小麦条锈病在四川连年大发生。究其原因,最主要是大面积生产小麦品种抗锈性的丧失。分析本省小麦品种抗锈性现状,是新审定品种区试抗性水平有较大提高,但新品种一经大面积推广后抗锈性衰退现象十分严重。目前本省已采取多种有效措施,包括提高品种审定时的抗锈性指标,实行老品种“退役”制,加大品种更换的力度和合理品种布局,以及建立科学的抗锈性评价体系等。但要进一步提高本省小麦品种的整体抗锈性水平以控制小麦条锈病的发生和为害,还需要加强品种抗源及其抗性遗传背景的研究,加强学科间协作和对外交流,加大良种补贴面等。
In recent years, wheat stripe rust occurred in successive years in Sichuan. The reason, the most important is the loss of rust resistance of large-scale production of wheat varieties. Analysis of the current situation of the rust resistance of wheat varieties in the province, the newly approved varieties of regional test resistance levels have greatly improved, but after a large area of new varieties of anti-rust recession is very serious. At present, the province has taken a variety of effective measures, including improving the rust resistance of varieties at the time of validation, the implementation of old varieties “retired ” system, increase the variety of replacement efforts and reasonable varieties of layout, and establish a scientific evaluation system of rust Wait. However, to further improve the overall anti-rust level of wheat varieties in the province to control the occurrence and damage of wheat stripe rust, further research on the genetic background of anti-source and resistance of cultivars should be conducted, inter-disciplinary cooperation and foreign exchange should be strengthened, Face and so on.
