摘　　要：介绍了培杂丰2的选育过程和主要特征特性,指出培杂丰2是利用两系不育系培矮64S为母本、以优质恢复系R0245为父本配组育成的高产高抗感温型两系杂交稻新组合,具有丰产性好、高抗稻瘟病、品质较优、生育期适中、易制种等优点,2006年12月通过了广东省农作物品种审定;同时总结了该组合高产栽培与制种的技术要点。Peiza-feng2 is a new two-line temperature-sensitive type hybrid combination with high yielding and high resistance to disease , which was bred through cross breeding between the Dual-purpose mala sterile line Peiai 64S as female parent and restorer R0245 with fine grain quality as male parent. It was characterized by high yield, high resistance to rice blast, fine grain quality, moderate growth duration and easy seed production. The breeding procedure, characteristics, major techniques of cultivation and hybrid seed production of Peiza-feng2 were introduced in this paper. It was registered and released for commercial production in Guangdong province in December, 2006.
