    摘要:

    本文介绍了日本水稻育种成果及存在问题,近60年来日本农林省登记的品种有352个,连续种植20年的品种有越光、笹锦,日本晴等。试验表明,随年代的演变选育的品种有高产、早熟、矮秆,抗倒伏,抗稻瘟病的趋势,米质和耐冷性也明显提高。但近年来出现品种单一化现象,遗传资源也很贪乏,就育成的品种数量和作用而言,育种进展不大。

    Abstract:

    This report introduces the results and major problems of rice breeding in Japan. In the last 60 years, 352 rice varieties were registered in the Ministry of Agriculture and Forestry for Japan. Some varieties have been grown for 20 years running, such as Koshihkari, Sasanishik, Zhovbare etc. The experiments had shown that the selected varieties are trending to high-yield, early-maturity, short-straw, loding-resistant, resistent to rice blast and significant inereas in rice quality and coldtolerance, with the development of years. As far as the number of varieties and yield goes, work on selecting new varieties have slowly developed, which genetic resource were very po (?) r and the phenomenon of singular varitey has arisen in recent years.
