摘　　要：】１９８８～１９９７年，对１６８３份恢复系及材料的抗病性鉴定，筛选出抗瘟性恢复系及材料２５５份。杂交稻恢复系与Ｆ１代之间的抗病性为显性遗传关系。利用抗病恢复系ＣＤＲ２２，育成杂交稻推广品种３个。The resistance to rice blast caused by Magnaporthe grisea of 1683 hybrid rice restorer lines varieties of materials were identified from 1988 to 1997. 255 varieties or materials were screened that were resistant to blast. There was a dominant inheritance between F 1 hybrids and restorers, and 3 high yielding varieties of hybrid rice were bred using the restorer CDR 22 that was resistant to blast.
