摘要
条锈病和叶锈病是严重威胁我国小麦生产的两种主要病害。为了挖掘与利用抗病资源,以改良我国小麦品种的抗病性,利用人工接种的方法对我国小麦微核心种质中的57份材料分别进行了条锈病与叶锈病成株期抗性评价。结果表明,具有条锈病成株抗性的材料有35份,具有叶锈病成株抗性的材料有27份。兼抗2种病害的材料有14份,占全部材料的24.6%。在所有抗病材料中,对条锈免疫或近免疫的有9份,对叶锈免疫或近免疫的有10份,对2种病害的抗性都达到近免疫或高抗的材料有3份,分别为梭条红麦、郑引4号和浙麦1号。本研究不仅为抗条锈和叶锈病育种提供了有价值的抗源材料,也为深入研究我国小麦微核心种质提供参考。
Stripe rust and leaf rust are two main diseases threatening wheat production seriously in china.The resistance of wheat varieties in China can be improved effectively by digging and utilizing the germplasm resources of wheat with resistance to these diseases.In this study,57 accessions of Chinese wheat mini-core collections were inoculated to evaluate their resistance to stripe rust and leaf rust at adult stage,respectively.The results showed that,there were 35 cultivars with adult stage resistance to stripe rust and 27 cultivars with adult stage resistance to leaf rust.There were 14 cultivars with adult stage resistance to both stripe rust and leaf rust,accounting for 24.6%of all materials.Among all the resistant cultivars,9 were immune or near immune to stripe rust and 10 were immune or near immune to leaf rust.Furthermore,there were 3 cultivars,Suotiaohongmai,Zhengyin 4 and Zhemai 1,with nearimmune or high resistance to these 2 diseases.This study not only provided valuable resistant resources for wheat breeding,but also provided reference for further studying the Chinese wheat mini-core collections.
