小麦条锈病在我省主要是在滇中、滇西及滇西北、滇西南的部分县发生危害,是小麦稳产高产的主要病害。目前,在这些地区的一些主要生产品种如“阿波”、“778”、“云麦26”、“24—26”、“大理32”等品种均高度感染条锈病。同时随着小麦栽培水平的不断提高,锈病流行危害的频率亦渐加大。因此,小麦条锈病的危害已成为当前这些地区进一步发展小麦生产的障碍,是急待解决的问题。选育抗锈良种是防治锈病的一项经济有效的措施。但抗锈良种在生产上常常出现抗锈性变化而失去利用价值。60年代以来,我省“南大2419”及“阿波”小麦的抗条锈性
Wheat stripe rust in our province is mainly in central Yunnan, western Yunnan and northwestern Yunnan, southwestern part of the county of harm, is the main wheat yield stable and high yield. At present, some of the major production varieties in these areas such as “Apollo”, “778”, “Yunmai 26”, “24-26” and “Dali 32” are all highly infected with stripe rust. At the same time, as the level of wheat cultivation continues to increase, the frequency of the epidemic is also increasing. Therefore, the harm of wheat stripe rust has become an obstacle to the further development of wheat production in these regions, which is an urgent issue to be solved. Breeding rust-resistant varieties is a cost-effective measure to prevent rust. However, rust-resistant seeds often appear in the production of rust-resistant changes in the loss of value. Since the 1960s, our province “Nanda 2419” and “Abo” wheat stripe rust resistance
