Barley yellow dwarf viruses (BYDVs) are recognized as serous pathogens of wheat,which is transmitted by different species of cereal aphids in a circulative, non-propagative manner.It is critical to find diverse sources of resistance to reduce yield losses caused by virus and its vector aphids.From 2007 to 2013, the identification and evaluation of resistance of 251 wheat resources to BYDV-GAV and its vector Sitobion avenae were carried out by artificial inoculation of viruliferous aphids in the field.The results showed five varieties of KOK, KOK IPPCAS, Astron, tp19 and Amigo-6 from abroad are not only resistant to aphids but also to BYDV-GAV.Six cultivars showed resistance to BYDVGAV, including 00zhong13, Zhong4, Xinong979, Linyou21, 878 and H9020-17-25-6-4.

摘要 新课程标准提出,要实现学生从“接受式学习”向“探究式学习”的转变,教师由知识外在灌输型向学生内在感悟型的转变。在以教师为主导,学生为主体的教学活动中,最关键的就是对问题情境的设置。创设适合学生身心发展和认知规律的问题情境可以充分调动学生的参与性,让学生围绕具体的问题展开探究性学习,使学生的思维在问题的思考与探索中得到促进与发展,让学生的自主性、独立性、能动性和创造性得到张扬,真正成为学习的
