摘　　要：对８０份籼型杂交水稻恢复系的抗褐飞虱特性鉴定表明，３０份材料对褐飞虱抗性达中抗以上水平，其中１２份材料的持抗性优于ＡＳＤ７。将这１２份材料的抗级为０～３级、持抗期＞７ｄ的优质抗性材料归为一级抗性材料。经杂种优势的测定、外观米质评价、白叶枯病和稻瘟病抗性鉴定，筛选出对两病一虫达中抗水平，与协青早Ａ的杂种产量比对照汕优１０号增产１２．９％的杂交水稻新恢复系埃红／台１０５９；以及高抗褐飞虱、高抗稻瘟病、中抗白叶枯病且外观米质极好的恢复系ＬＳ－２／密阳４６。The characters of resistance to brown planthopper (Nilaparvata lugens ) of 80 restorers in indica hybrid ricewere evaluated. It was found that 30 restorers express medium- or higher-grade resistance. Twelve of them show super toASD7 in durable resistance. These materials, 0- 3 degree of resistant grade and durable resistance>7d, were divided intofirst degree of resistant materials. After testing heterosis, assessing apparent rice quality, evaluating resistance to rice leafblight and rice blast, two new restorers were selected. One restorer, Aihong/Tai 1059, expressed medium grade of resistanceto rice leaf blight and rice blast and brown planthopper. The yield of its hybrid with Xieqingzao A increased 12. 9% than thatof CK Shanyou 10. Another, LS-2/Milyang 46, possessed such characteristics as high resistance to brown planthopper andrice blight, medium resistance to rice leaf blight, and excellent apparent rice quality.
