摘　　要：培矮６４Ｓ／Ｃ９６２１１是以两系籼型不育系培矮６４Ｓ为母本，以粳型恢复系Ｒ１８３为父本杂交的杂种一代。该组合具有良好的株叶形态与旺盛的生理机能，株型紧凑，上部３片功能叶修长、挺直、窄凹、厚实，基本符合袁隆平提出的水稻两系法超高产育种株叶形态模式；杂种优势强，产量高，比汕优６３（作中稻）、汕优６４（作二晚）分别增产１０％和２０％以上；中抗稻瘟病和白叶枯病；米质符合国家二级米标准；可以在生产上直接应用。Peiai 64S/C96211 was a hybrid rice F1 generation of crossing twoline Indica sterile line as female parent with Japonica restoring line R183 as male parent.The combination has compact plantleaf type and powerful physiological function.Its upper three functional leaves were slenden straight narrow and thick.All these characteristics corresponded to the plantleaf type model of super high yield rice which was proposed by MrYuan Longping.Peiai 64S/C96211 has strong heterosis and increased yield over 10%20% than Shanyou 63 (planted as middleseason rice)and Shanyou 64(planted as lateseason rice).Its resistances to blast and blight were middle,and rice quality was up to the second class of the Ministry Criteria for high grain quality rice.The combination may be applied directly in the production.
