Screening and identification of resistant peanut varieties and strains to Aspergillus flavus

Several peanut varieties,including cultivars and varieties from ICRISAT and varieties (lines) developed by Fujian Agriculture and Forestry University,were inoculated with powerful Aspergillus flavus strains to determine their resistance to the fungal infection. The results showed that three varieties,including Minhua 6,had greater fungal resistance than the controls,Kanghuang 1 and Yueyou 9. The infection rate was less than 30% and the infection index less than 6.0. These varieties could provide resistance genes for A.flavus resistance breeding. Kanghuang 1 is a MS variety to A.flavus. The evaluation of peanut’s resistance to A.flavus was also discussed.
