湖南是当前我国水稻播种面积最大的省份,野败型雄性不育系发现和利用为我国杂交稻三系配套作出了开创性贡献。及时总结湖南省育种成果,有助于育种家高效选择亲本,减少配组盲目性。基于VBA的编写程序算法,分析了“中国水稻品种及其系谱数据库”中收录的湖南审定品种。1985—2021年,湖南省级审定水稻品种共1 085个。分析发现水稻品种的单产稳步提高,食味品质有改善,稻瘟病和白叶枯病抗性得到改良。

Hunan has the largest planting area and secondary highest output of rice in China. The discovery and utilization of wild abortive male sterile line has made a pioneering contribution to the three lines matching of hybrid rice. Summarizing the rice breeding experience and results in Hunan will help breeders to select breeding parents, thus reducing blindness. Based on VBA programming, the algorithm is compiled to analyze the variety records of Hunan included in the Database for Chinese Rice Varieties and their Genealogy. From 1985 to 2021, 1 085 rice varieties were registered in Hunan. It was found that the yield per unit area of varieties increased steadily, the eating quality and the resistance to rice blast and bacterial blight were improved.
