| Abstract: | Objective] The study was to provide the theoretical basis to improve the yield level of rice.Method] With rice varieties of Qianyou 88,Yinong 1,Qiannanyou 2058 and Ⅱyou 838(CK)as materials,the high yield characteristics of different varieties was studied.Result] The yield of Qianyou 88,Yinong 1,Qiannanyou 2058 was 12 990.0,12 823.5 and 12 460.5 kg/hm2 resp.,increasing by 20.0%,18.5% and 15.1% than that of CK varietyⅡyou 838.Compared with CK variety,the effective spikes of Qianyou 88,Yinong 1,Qiannanyou 2058 were increased by 15.1%,24.5% and 3.5% resp.;their 1 000-grain weight were increased by 2.7%,4.2% and 11.4% resp.;their total spikelets number were increased by 10.5%,11.7% and 8.3% resp.and their biomass was 187.0,98.0 and 220.0 g/m2 higher.The sink capacity of Qianyou 88 and Yinong 1 were 13.4% and 16.4% bigger than that of CK resp.The advantage of dry matter production of the 3 varieties above manifested at the middle and later stage.Conclusion] The average yield of Qianyou 88,Yinong 1 and Qiannanyou 2058 reached 12 757.5 kg/hm2. |
