Test of Selection and Evaluation of New Hybrid Middle-season Indica Rice Combinations in Tongling County

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
