23份中国小麦微核心种质抗叶锈性评价
Evaluation of Wheat Leaf Rust Resistance of 23 Chinese Wheat Mini-Core Collections
摘要
Abstract
[Objective] The objective of this study was to determine the leaf rust resistance of 23 mini-core wheat accessions,and to detect the Lr genes related to resistance.[Method] Resistance evaluation and resistance gene postulation of the 23 accessions were carried out with 12 Puccinia triticina races with different virulences at seedling and adult stages.A series of molecular markers linked to wheat leaf rust resistance genes were used for marker test of these accessions.[Result] The 23 accessions from wheat mini-core collections all showed good resistance except Chinese Spring and were postulated to carry some resistance genes.Lr34 and unknown Lr genes in Huoqiu,Laoqimai,Fengmai 1 l,Shanhongmai,Hongheshangtou,Fumai,Galaohan and Zhengyin 4.Lr34 was found in Chinese Spring.Lr1 and Lr34 were found in Jianmai and Xiaofoshou.Lr34 and Lr32 were identified in Tongjiabaxiaomai and Honghuamai.Lr10,Lr34,Lr16 and Lr32 were postulated in Kefeng 3.Lr1,Lr2c and Lr32 were found in Atlas 66.Lr1 and Lr17 were postulated in Yannong 15.Lr26,Lr16,Lr42 and LrZH84 were found in Baitiaoyu.Lr26 combined with suggested Lr14a in Muzongzhuoga.Lr1,Lr34 and Lr32 were postulated in Jinhuangmai.Lr26,Lr37,LrZH84 and maybe Lr15 were detected in Yunmai 34.Lr1 and Lr16 in Bainong 3217.Besides,Bailanghuimai and Shanmai may carry un-known resistance genes to wheat leaf rust.[Conclusion] The results indicated that the resistance genes in response to leaf rust disease were relatively richer in the 23 Chinese wheat mini-core collections,and the Chinese wheat mini-core collections could be applied in breeding programs for leaf rust resistance.关键词
