早稻优质米新品系“92010”（金丝月牙）研究初报

A PRIMARY STUDY ON A NEW EARLY RICE VARIETY“92010”(JIN-SIYUE-YA) WITH HIGH QUALITY OF RICE GRAIN

通过复合杂交和连续选择方法培育出稳定遗传的早稻优质米新品系＂９２０１０＂。连续两年的试验和示范种植的结果表明：＂９２０１０＂的生育期比鄂早６号早３～４天，产量与鄂早６号相当，稻米品质为一级籼米，抗稻瘟病和白叶枯病，适合在湖北及类似地区作中迟熟早稻种植。

A new early rice variety '92010' with high quality of rice grain was successfully breeded out by hybridization and systematic sclection.The results of the testing and cultivating as an examplary role for the great scale of production during 1993～ 1994 showed:the growing period duration of '92010' was 3～4 days earlier than E-Zao-Liu-Hao(a main cultivating variety in Hubei Province),the '92010' was the same as the control variety EZao-Liu-Hao in the yield latent potentiality.The rice grain quality of '92010' was the first class of the long shaped corn rice according to the national rice grain quality standard.The resistance to rice blast and leaf blight was more higher than the control varieties.So the '92010' is suit to plant as an early rice with the middlelate mature-period in Hubei Province and similar areas.
