Resistance to Wheat Scab and Agronomic Traits of Some Wheat Materials from China and Abroad in Huang-huai Wheat Area

32 wheat materials of China and overseas were examined on resistance to wheat scab in Huang-huai wheat area by using artificial inoculation,and the relationships between resistance to wheat scab and agronomic traits were analysed .The results showed that all of the materials were infected by wheat scab,but severity of disease had significant differences,6 of them were identified as resistant(R),12 as moderately resistant (MR),9 as moderately susceptible(MS),5 as susceptible(S).The result showed that there were no correlation between resistance to scab and agromomic traits,such as plant height, spike length and spike density .
