Abstract:
A total of 1242 varieties including 1182 accessions of germplasm and 60 breeding lines of peanut (Arachis hypogaea L.) were screened for pod rot disease resistance at fields. There were 5 crop seasons screening from 1996 fall crop to 1998 fall crop. Almost all tested varieties were susceptible to pod rot disease, but Spanish type varieties were more resistant than other types when comparison of means of pod rot severity for botanical types of peanut. Four Valencia type varieties (VA111、VA114、VA220 and VA221) and one Virginia bunch type variety (VB186) showed highly resistant to pod rot disease and all of them introduced from America could be used as breeding parents.
