】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。
From 1988 to 1997, the resistance of 1683 restorer lines and materials were identified, and the restorer lines and 255 materials were screened out. The disease resistance between hybrid rice restorer and F1 was dominant genetic relationship. The restorer line CDR22 was used to breed three hybrid rice varieties.
