摘要

农作物审定品种退出机制构建于《中华人民共和国种子法》《主要农作物品种审定办法》等法律法规基础上,是我国品种管理的主要措施和手段之一。回顾了我国审定品种退出制度的发展,从数量分布、审定时间分布、品种使用年限等方面进行了统计分析,以期从品种退出角度,为品种管理与利用机构提供系统、完整的参考与技术支持。结果表明,我国在品种退出相关政策上逐步改进;截至目前,停止推广品种发布于2008—2015年,共计11批991个,涉及稻、小麦、玉米、棉花、大豆、油菜和马铃薯等7种农作物;停止推广品种在农作物种类、品种数量上分布不均,最多的是稻品种(占总退出品种数的31.58%),年退出品种数最多的是2012年(257个),最少的是2011年(21个);品种使用年限在不同农作物间、相同农作物间的差别均较大, 2008—2015年所有停止推广品种的平均使用年限为12 a, 2009—2015年所有停止推广品种的平均使用年限为10 a。
        The withdrawal mechanism of crop variety certification was based on the laws and regulations,such as "The seed law of the People's Republic of China" and" The methods for examination and approval of main crop varieties",which was one of the main measures and means of variety management.The development of withdrawal mechanism of crop variety certification was reviewed,and the quantity distribution,the authorized year distribution,the service year of different withdrawn national authorized crop varieties were studied,so as to provide more systematic and technical support for the relevant seeds management and utilization institutions.The results showed that the withdrawal policy of variety had been gradually improved.From 2008 to 2015,there were 991 varieties of 11 batches had been withdrawn,covering 7 crops including rice,wheat,maize,cotton,soybean,rape and potato.The withdrawn varieties were unevenly distributed in terms of crop types and varieties number.The varieties number of rice was the largest(accounting for 31.58% of the total number of withdrawn varieties).The withdrawn varieties number was the largest in 2012,which was 257,and the least was in 2011,which was 21.The service life of varieties was largely different among different crops and different varieties of the same crop.The average service life of all stop-promoting varieties from 2008 to 2015 was 12 years,and the average service life of all stop-promoting varieties from 2009 to 2015 was 10 years.
