江西省2012～2017年审定水稻品种与趋势分析

Analysis of Approved Rice Varieties and Their Trend in Jiangxi Province from 2012 to 2017

统计分析了江西省2012~2017年审定的水稻品种的主要性状和发展趋势。结果表明,江西省近6年来审定通过了190个早、中、晚稻品种和8个特种稻品种。在190个早、中、晚稻品种中有杂交稻品种186个,占97.89%,而常规稻品种仅4个,占2.11%;有晚稻品种107个,占56.32%,而早稻品种仅30个,占15.79%。优质稻品种共99个,占总品种数的50%。产量呈逐年上升趋势,但稻瘟病抗性水平偏低,抗病育种有待加强。种子企业是新品种选育的主体,科企合作也是新品种选育的中坚力量。

This paper statistically analyzed the main traits and developmental trend of approved rice varieties in Jiangxi province from 2012 to 2017.The results indicated that 190 early,middle and late rice varieties and 8 special rice varieties had been approved in Jiangxi province in the past 6 years.Among the 190 varieties,there are 186 hybrid rice varieties（accounting for97.89%）,4 conventional rice varieties（2.11%）,107 late rice varieties（56.32%）,and 30 early rice varieties（15.79%）.Ninety-nine high-quality rice varieties have been approved,accounting for 50% of all varieties.The yield of these approved rice varieties showed a rising trend during 2012 ～ 2017,but their resistance to rice blast was relatively low,thus rice disease-resistant breeding needed to be further strengthened.The seed enterprises were the main body of rice new variety breeding,and the cooperation between the enterprises and the research institutions was also the core strengths for rice new variety breeding.
