摘　　要：恢复系明恢８２是以ＩＲ６０作母本，与圭６３０杂交选育而成。具有恢复谱广，配合力好，抗稻瘟病，米质好。用明恢８２配制的汕优８２具有抗稻瘟病性强，大穗粒多，丰产性好，穗期耐高温，结实率高。参加全国、福建省、三明市三级区域试验，产量显著比对照增产，１９９８年３月通过了福建省品种审定，被福建省、三明市列为重点示范推广新组合。该组合已在全国南方稻区各省大面积示范推广。还介绍了明恢８２及其配制的组合汕优８２主要农艺学与生物学特征特性。Minghui 82, developed through crossing IR 60 to Gui 630, is a new indica restorer line with wide scope of restoring and good combining ability. The hybrid combination shanyou 82, i.e. Minghui 82×Zhenshan 97 A, has the characteristics of strong resistance to blast, of large panicle and large grain number, high yield and seed set, good grain quality and tolerance to high temporture in panicle stage. The average yield increases by 7.75% compared with the ckeck in regional, provincial and national yield trials. It was examined and approved for release in Fujian Province in 1997. It was selected as an important item for extension in Sanming City and Fujian Province, and has been extended to large area in southern provinces of China. The major agronomic and biological characters of Minghui 82 and its combination Shanyou 82 are stated in this paper.
