摘　　要：从1981～2003年,通过在小麦条锈病、白粉病、赤霉病若干个重病区设点,多点异地,自然发病与人工接种相结合,并以反应型与严重度相结合,评价品种的抗病性,提高了鉴定的准确性和可靠性。本文对抗源多样化、品种的合理布局、持久抗性等方面总结了经验与教训。The identification of wheat resistance of stripe rustpowder mildew and head blight was carried out by Institute of Plant Protection,Sichuan Academy of Agricultural Science in disease in recent 23 years.According to the reaction type and disease severity of disease,the resistant level of tested materials was evaluated.Based on disease resistant level,many resistant materials were screened out and recommended to breeder,which accelerated the wheat resistance breeding works in Sichuan.The experiences about the diversification of resistant genes and cultivars planting in different regions was also discussed,to improve the efficiency of wheat resistance identification to benefit wheat resistant breeding.
