摘要

以農業試驗所保存之落花生種原1182個及育成的高級品系60個，合計1242個品種（系），從1996年秋作至1998年秋作，每年春秋二期作在雲林縣元長鄉感病田進行抗莢果黑斑病篩選；結果顯示落花生植物型間的莢果黑斑病罹病度有差異，平均以Spanish type稍低；而地區間則以美洲的品種較具抗病。種原篩選獲得5個較抗病品系，其中4個屬於Valencia(VA111、VA114、VA220、VA221)，1個為Virginia bunch(VB186)，均來自美洲，將來可做為育種之材料。

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.
