摘　　要：统计分析了重庆市2011—2022年12 a的两系法杂交水稻推广种植面积、主导品种及品种审定情况。结果表明,重庆两系法杂交水稻在推广种植面积上增长迅速,种植面积占比由2011年的5.4%增长到2020年的35.5%;12 a来重庆市农业推广部门对两系法杂交水稻推广力度不断增大,主导品种的数量和比例一度超过三系法杂交水稻;而重庆市在两系法杂交水稻的品种审定上却始终徘徊不前,审定品种数量少,难以满足当前两系法杂交水稻产业发展需求。The planting area,number of dominant varieties and variety registration of two-line hybrid rice in Chongqing from 2011 to 2022 were analyzed statistically.The results showed that the proportion of two-line hybrid rice area to total hybrid rice area in Chongqing increased rapidly from 5.4%in 2011 to 35.5%in 2020.In the past 12 years,the agricultural extension departments of Chongqing had been increasing the promotion of two-line hybrid rice,and the number and proportion of dominant varieties of two-line hybrid rice once exceeded those of three-line hybrid rice.However,the number of registered and released two-line hybrid rice varieties in Chongqing was small,which is difficult to meet the development needs of the current two-line hybrid rice industry.
