摘要
对湖南省2010-2015年审定的水稻品种的类型及其产量、品质、抗性等主要性状进行分析,结果表明,湖南省近6年来审定的197个水稻品种中,杂交稻品种多达184个,占审定品种总数的93.4%,而常规稻仅13个,占6.6%,优质稻品种（组合）8个,占4.1%;产量较对照增产幅度在2.90%-17.10%之间,年度间产量有稳步上升的趋势,但与对照相比,表现出平缓态势;综合抗性指数整体水平中等偏低;品质育种和抗病育种有待进一步加强。种子企业成为水稻育种研发的主体,但教学科研单位仍是新品种选育的重要力量。
By statistical analysis about the yield, quality and disease resistance the rice varieties, approved for release by the Crop Cultivar Appraisal Commission of Hunan province in Hunan province regional tests during 2010 -2015,The 197 rice varieties examined and approved in Hunan Province in the past 6 years,among them,up to 184 hybrid rice varieties, accounting for 93. 4% , while the inbred rice only 13, accounting for 6. 6% ,8 high quality rice varieties （ combinations）, accounting for 4. 1%. The range of seeds yield was 2. 90% -17. 1% higher than that of controls. There is steady increase in the yield during the 6 years, but it showing a gentle trend when compared with the control. The whole level of comprehensive resistance index is low. Quality breeding and disease resistance breeding need to be further strengthened. Seed enterprise become the main research and development body in rice breeding, while the teaching and scientific research unites are still the important force for new variety breeding.
