摘　　要：对滇麦7号和滇麦12号在云南省7个试验点[丽江(海拔2240 m)、楚雄(海拔1773 m)、红河(海拔1672 m)、保山(海拔1654 m)、昆明(海拔1603 m)、玉溪(海拔1507 m)和临沧(海拔1476 m)试验点]开展适应性评价,并进行成株期抗条锈基因(QYr.nwafu-4BL、Yr5、Yr10、Yr15、Yr18、Yr26、Yr29、Yr39、Yr41、Yr65、Yr67、Yr78和Yr80)检测,旨在为推动云南省小麦优势区域布局和抗条锈病品种选育提供理论参考。结果表明,红河试验点2个小麦品种产量较高,其生育期、株高、群体结构和抗逆性均表现较优异;2个品种间比较,滇麦7号的农艺性状表现较优异。对2个品种进行成株期抗条锈基因检测发现,滇麦7号携带2个抗病基因Yr78+QYr.nwafu-4BL,滇麦12号携带4个抗病基因Yr5+Yr65+Yr67+QYr.nwafu-4BL。综上,红河试验点的农艺性状表现较优,滇麦7号表现优于滇麦12号,适合在全省推广种植;2个品种在成株期表现出较高的条锈病抗性,其抗性在一定程度上是由抗性基因的加性效应决定。Adaptability evaluations of Dianmai 7 and Dianmai 12 were conducted at seven experimental sites in Yunnan Province,including Lijiang(altitude of 2240 m),Chuxiong(altitude of 1773 m),Honghe(altitude of 1672 m),Baoshan(altitude of 1654 m),Kunming(altitude of 1603 m),Yuxi(altitude of 1507 m)and Lincang(altitude of 1476 m),and the stripe rust resistantce genes(QYr.nwafu-4BL,Yr5,Yr10,Yr15,Yr18,Yr26,Yr29,Yr39,Yr41,Yr65,Yr67,Yr78 and Yr80)were detected at adult plant stage,so as to provide theoretical references for the promotion of the layout of dominant regions of wheat and the breeding of cultivars with resistance to stripe rust in Yunnan Province.The results showed that the two wheat cultivars at the Honghe experimental site had high yields,and their growth period,plant height,population structure and stress resistance all performed well;Dianmai 7 exhibited superior agronomic traits compared with Dianmai 12.Detection of stripe rust resistant genes of the two cultivars at adult plant stage revealed that Dianmai 7 carried two resistance genes,including Yr78+QYr.nwafu-4BL,and Dianmai 12 carried four resistance genes,including Yr5+Yr65+Yr67+QYr.nwafu-4BL.In conclusion,the agronomic traits of the Honghe test site are superior,and Dianmai 7 performs better than Dianmai 12,which is suitable for popularization and planting in Yunnan Province;the two cultivars show higher resistance to stripe rust at adult plant stage,and their resistance is partly determined by the additive effect of resistance genes.
