摘　　要：[目的]筛选适合安徽省铜陵地区种植的优质、高产、抗性强、生育期适中、综合性状优良的新品种(组合)。[方法]对引进的12个中籼水稻品种(组合)进行区域试验,分别为Y两优342、扬两优818、中优9号、Y两优90、玉优12、徽两优932、徽两优348、宝两优6号、G两优1号、五山丝苗、Y两优8025、Y两优6611,对照为Ⅱ优838。[结果]徽两优348产量居第1位,比对照增产10.93%,品质5等;五山丝苗产量居第2位,比对照增产10.26%,品质5等;Y两优342产量居第3位,比对照增产9.60%,品质5等;G两优1号产量居第4位,比对照增产8.94%,品质3等;Y两优90产量居第5位,比对照增产8.61%,品质3等;徽两优928产量居第6位,比对照增产6.62%;玉优12产量居第7位,品质4等。Y两优8025、Y两优6611产量比对照增产5.00%,Y两优8025品质5等,Y两优6611品质较好,为2等。宝两优6号产量一般,扬两优818、中优9号减产。[结论]筛选出的高产组合徽两优348、五山丝苗、Y两优342与高产优质组合G两优1号、Y两优90适宜于铜陵县推广种植;Y两优8025、Y两优6611可在铜陵县示范种植;宝两优6号、扬两优818、中优9号不适宜在铜陵县种植。[Objective] The aim was to screen new hybrid middle-season indica rice cultivars （combinations） with good quality, high yield, strong resistance, good comprehensive characteristics and suitable for planting in Tongliang Area of Anhui Province. [ Method] Introduced 12 middle-season indica rice cultivars（combinations）, Y liangyou 342, Yangliangyou 818, Zhongyou No. 9, Y liangyou 90, Yuyou 12, Huilian- gyou 932, Huiliangyou 348, Baoliangyou No. 6, G liangyou No. 1, Wushansimiao, Y liangyou 8025, Y liangyou 6611, were chose to con- duct the regional test, and taking U you 838 as control. [ Result] The yield of Huiliangyou 348 was the first, increased 10.93% than that of control, and its quality belonged to 5 grade ; the yield of Wushansimiao was the second, increased 10.26% than that of control, and its quality belonged to 5 grade ; the yield of ~ liangyou 342 was the third, increased 9.60% than that of control, and its quality belonged to 5 grade ; the yield of G liangyou No. 1 was the fourth, increased 8.94% than that of control, and its quality belonged to 3 grade; the yield of Y liangyou 90 was the fifth, increased 8.61% than that of control, and its quality belonged to 3 grade ; the yield of Huilaingyou 928 was the sixth, in- creased 6.62% than that of control ; the yield of Yuyou 12 was ihe seventh, and its quality belonged to 4 grade. The yield of Y liangyou 8025 and Y liangyou 6611 both increased 5.00% than that of control, the former＇ s quality belonged to 5 grade, and the latter＇ s quality was better and belonged to 2 grade. The yield of Baoliangyou No. 6 was normal, and that of Yanglaingyou 818 and Zhongyou No. 9 reduced. [ Conclu-sion ] The selected high yield combinations are Huiliangyou 348, Wushansimiao, Y liangyou 342, and the selected high yield and good quality combinations are G liangyou No. 1 and Y liangyou 90, they are all suitable for planting in Tonghng Town; Y liangyou 8025 and Y liangyou 6611 are suitable for demonstration planting in Tongling Town; Baoliangyou No. 6, Yangliangyou
