四川省小麦品种多点抗性监测试验总结（To summarize the resistance monitoring test of Wheat Varieties in Sichuan Province） To summarize the resistance monitoring test of Wheat Varieties in Sichuan Province Sichuan varieties, resistance to stripe rust and near isogenic lines with a total of 102 branches in Zitong, Pengan, Pingshan plant, Yaan, Guangyuan and Pixian get stripe rust disease nursery, the performance of the material such as table 1. Among them, Zitong, Pengan, Yaan, and Guangyuan five nursery natural disease, Pixian nursery inoculation, the strain from Sichuan collected samples of reproduction, a new type of pathogenic disease contains Chuanmai 42. Yaan nursery due to rain, serious lodging, the order is wrong, is not included in the results. In four nursery naturally occurring, showed disease resistance materials of Chuanmai 42, wheat 9, apricot wheat No. 2 and No. 8 wheat, Mianmai 37, Mianmai 39, Chuanmai 43, Guinong 22-1, Guinong 001, 54, R97, CP93-10-3-2, on 99-1-22V-2 and SW18155 30375 and Chuannong 18 and Chuannong 19 and Chuannong 23, Chuanmai 46 and Chuanmai 47, Mianmai 42, C1, C5, Le Mai, Chuannong 25, Chuanmai 50 and Chuanmai 52 and Chuanmai 51 and Chuanmai 45 and Chuanmai 43 and near isogenic lines, Yr5 Yr8, Yr9, Yr10, Yr15 and Yr26 were a total of 36, accounting for 35.3% of the total. Near isogenic lines of these resistant materials and near isogenic susceptible disease nursery in Pixian have showed Chuanmai 42, wheat 9, apricot wheat No. 2 and No. 8 wheat, Mianmai 39, Mianmai 42, C5, Le Mai, Chuanmai 43 and Chuanmai 45, Guinong, 22-1 Guinong 001, concept 54, Chuannong 25 and Yr26 a total of 14, accounting for 38.8% of the total.
