中国水稻杂种优势群划分的研究进展

Research Progress on Dividing Heterosis Groups of Rice in China

介绍了杂种优势群的定义及利用农艺性状,系谱关系和DNA分子标记技术构建杂种优势群的方法。综述了中国水稻育种家对水稻杂种优势群划分领域的研究工作进展,提出对中国水稻杂种优势群的划分不但能提高育种效率也是今后水稻杂交育种的必然趋势。

Heterosis groups＇definition and three methods which were mostly utilized in constructing heterosis groups were introduced in the paper. What＇s more, the research progresses about division of rice heterosis groups were given a detailed described. And the author also proposed that the more deeply researches on heterosis groups division of rice in China is necessary, for which would not only raising breeding efficiency, but also would be a inevitable tendency in hybrid rice breeding in future.
