摘　　要：与三系杂交水稻相比,两系水稻具有育种效率高、繁制种成本低、丰产优势强、品质相对优等优势,近年来在以重庆为代表的长江流域稻区得以迅速发展。为明确重庆市两系稻产业现状及发展趋势,本文统计了2006—2015年10年间重庆市两系水稻的种植面积、主推品种及两系品种的审定情况。结果显示,10年间两系稻在种植面积上呈明显的增长态势,2014年占水稻种植总面积的17.2%,推广面积最大的两系水稻品种是‘Y两优1号’和‘深两优5814’。在品种推广上,两系主导品种比例由2006年的5.9%上升到2015年的31.3%,且两系主导品种全为优质稻品种;在品种审定上,10年间重庆市审定(认定)的两系稻品种几乎全部为市外育种单位选育的品种,重庆市内农业科研单位在两系稻品种审定上一直保持着零的记录。Compared with three-line hybrid rice, two-line rice has the advantage of higher breeding efficiency,lower cost of seed production, higher yields, and relatively superior quality and so on. In recent years, varietyregistration and application of two-line rice was developed rapidly in the Yangtze River Basin represented byChongqing. In order to explicit current status and developing tendency of two-line rice industry, this articleanalyzed the planting area, main varieties and variety certification of two-line rice in Chongqing from 2006 to2015. The results showed that, the planting area of two-line rice increased rapidly in recent 10 years, covered17.2% of the total planting area in 2014, and‘Yliangyou No 1＇and‘Shenliangyou5814＇had the biggestspreading area. In cultivar promotion, the rate of dominant varieties of two-line rice rose from 5.9% in 2006 to31.3% in 2015, which had good quality. As to the variety certification, during the 10 years, almost all varietiescertificated by Chongqing were from other agricultural scientific research units, Chongqing agriculturalresearch unites maintained a record of zero in variety certification of two-line rice.
