土耳其8个小麦品种农艺性状及抗叶锈性分析
Agronomic Traits and Wheat Leaf Rust Resistance of Ten Turkey Wheat Accessions
摘要
Abstract
To evaluate the leaf rust resistance and the application prospect of eight wheat cultivars from Turkey, the agronomic traits were surveyed in whole growth period for two years and forty-four near isogenic lines (or single gene lines) in Thatcher background with known wheat leaf rust resistance genes were used as differential hosts. All genotypes were inoculated with eight pathotypes of Puccinina triticina at seedling stage. The results indicated that Lr1 ,Lr3,Lr17,Lr20 and some unknown resistance genes might present in the 8 accessions. As revealed by 20 molecular markers closely linked or co-segregated with part of the known Lr genes,the 8 accessions from Turkey were postulated to carry 4 resistance genes, such as Lr1 , Lr3 , Lr1 7 and Lr20 in YJ000900 , Lr1 , Lr1 7 and Lr2O in YJ000906,Lr7 in YJ000901 , YJ000902 , Y J000904 , Y J000905 and YJ000907. However, Lr9 , Lr19, Lr20,Lr21, Lr24 , Lr26 ,Lr28 ,Lr29 ,Lr34 ,Lr35, Lr37,Lr38 and Lr47 were not detected in the 8 accessions. The results showed that 8 wheat accessions from Turkey have poor resistance to wheat leaf rust,cold hardiness and lodging,and low production. These indicate that the test accessions are not suitable for releasing in China and for leaf rust resistance resource.关键词
