摘要
3年研究结果表明,汕优242比当前生产上推广组合威优49早热2d,两者产量水平相当,汕优242稻米品质为二级籼米,3个主要米质指标均优于威优49;对白叶枯病和稻瘟病的抗性及苗期抗寒性也明显优于威优49。该组合适合在我省作中迟熟早稻种植。
The Results of the studies for three years showed :The growth period of the new combination Shan -you 242 of early hybrid rice in normal season was 2 days short than the control combination Wei-you 49,which is a present commercial combination. The yield of 2 combinations were very close. The quality of rice grain of Shan - you 242 was the second grade of the polished long - grained nonglutinous rice,Its three indexes of the quality were all better than Wei - you 49's. The resistance to rice blast,rice leaf blight and low temperature in the stage of young plant was more powerful than that of Wei - you 49 too. According to the results it may be thought that Shan -you 242 is suitable as a middle -late combination of early hybrid rice planted in Hubei.
