Screening techniques and sources of resistance to Fusarium head blight - Mexico, DF (Mexico) CIMMYT : 1988 - Printed

Fusarium head blight of wheat (FHB) causes great losses in wheat grain yield and animal production in the Yangtze River region of China. More than 300 FHB-resistant wheat sources have been selected. About 40 of them have been used in wheat breeding. The predominant species identified from 2450 samples of isolates from 21 provinces of China was Fusarium graminearum. A significant difference was found in virulence of isolates. But no pathogenic specificity of isolates of F. graminearum was found. There were no significant differences in pathogenicity between ascospores and conidia or between 1 to 2 and 100 spores per 5 micro L suspension. Inoculation
