摘　　要：采用多菌系人工混合接种鉴定和不同生态试点自然病害鉴定相结合的病害鉴定方法 ,对常规有性杂交、系谱选育成功的小麦创新种质进行了抗锈性和生态适应性鉴定。结果表明 ,小麦创新种质YV98- 15和YV98- 30 15对接种条锈病菌和不同小麦生态试点的条锈病菌具有良好的抗病性 ,并有良好的生态适应性 ,可作为广适性和条锈病的抗源亲本利用 ;除玉溪、德宏田麦和楚雄地麦生态型外 ,YV97- 32、YV98- 16、YV99- 10 19和YV97- 12 14可用作叶锈病的抗源利用 ;所有参试材料对所有生态试点的秆锈菌具有良好的抗病性 ,可用作小麦秆锈菌的抗源亲本 ;丽江、昆明田麦生态型的条锈病菌 ,以及玉溪、德宏田麦和楚雄地麦生态型的叶锈病菌可能与接种病菌不同 。To appraise the rust resistance and ecologiccl adaptability of wheat germplasm that developed by hybridization and pedigree method,the methods of multilian pathogen inoculation and field disease resistance in different environments were used.The result indicated that the stripe rust resistance of YV98 15 and YV98 3015 was excellent in both inoculation and field test conditions.They could be exploited as parents with wide adaptability and stripe rust resistance.YV97 32,YV98 16, YV99 1019 and YV97 1214 could be exploited as parents of leaf rust resistance except the upland ecotypes from Yuxi and Dehong and Chuxiong.Stem rust resistance of the tested materials was excellent in all experimental sites,they could be exploited as parents of stem rust resistant germplasm.Stripe rust germ of paddy field ecotype from Lijiang and Kunming and leaf rust germ from Yuxi and Dehong and Chuxiong was possibly different from the inoculated germ,there seems to be existed new pathogenous form or gene.
