汕优桂33(原名汕优3624—33)是我所新育成的多抗高产新组合,生育期与汕优二号相似或稍早,抗性和产量均优于汕优二号,在南方稻区的华南南部可作双季早稻,在其他地方可作中、晚稻。一、组合来源及试验试种表现汕优桂33足用珍汕97A 与我所新育成的恢复系3624—33配制而成的,1977年晚稻用IR36与 IR24杂交,计划把 IR36的多抗性和IR24的丰产性结合起来,1980年挑选51个抗性好的株系大区观察,并进行测交筛选,
Shanyougui 33 (formerly Shanyou 3624-33) is a new combination of polyculture and high yielding that I developed. Its growth period is similar to Shanyou No.2 or earlier, its resistance and yield are better than those of Shanyou No.2, The southern part of the southern part of the rice area can be used as a double season early rice, and can be used for middle and late rice in other places. First, the combination of sources and experimental test performance Shanyou Guiying 33 with Zhenshan 97A and my newly-built restorer line 3624-33 prepared by the late rice in 1977 with IR36 and IR24 hybrid, plan to IR36 multi-resistance In combination with the high yield of IR24, 51 resistant and resistant strains were selected in 1980 for observation and screening by screening,
