| Abstract: | Objective] The study aimed to choose the good new medium hybrid rice indica combinations which can adapt to plant in Huoshan of Anhui Province. Method] With Ⅱyou838 as CK, the economic characters, yield performance and growth period traits of 11 medium hybrid rice indica combinations were compared, and the comprehensive situations of 11 medium hybrid rice indica combinations was reviewed. Result] Compared with CK, the yield of 11 medium hybrid rice indica combinations was higher, the yield of 26you543, IIyou346, fuyou198 were all increased over 8.0%; the plant height of each combinations was 116.9-130.8 cm, effective panicle was 166.5-228 panicle/hm~2, seed setting rate was over 80%, growth period was 139-142 d. Conclusion] 26you543, IIyou346 had high yield, good disease-resistance and grain quality, temperate growth period, they were suitable for planting in ecological region of Huoshan District. |
