| 摘 要： | “两系”杂交稻N_(98S)/特青从苗期就开始表现有多种形态和生理上的杂种优势。在产量构成因素中,表现平均优势的是亩有效穗数(10.52％)和每穗实粒数(31.25％);表现对“三系”杂交稻华优桂_(44)竞争优势的是亩有效穗数(15.92％)和千粒重(5.22％)两项。理论产量超亲优势达11.00％,竞争优势达19 76％。表明N_(9AS)/特青有较大增产潜力。

| Abstract: | From the seedling stage, N98S/Teqing, a two-line hybrid rice, exhibited heterosis in morphological and physiological characters.In yield components,the panicles per mu and filled grains per panicle of this hybrid rice showed 10. 52% and 31. 25% mid-parent heterosis respectively. It also presented heterosis over HuaYougui 44, a check strain of three-line indica hybrid rice , in panicles per mu by 15. 92% and 1000-grain weight by 5. 22%. The theoretical yield showed 11% heterobeltosis and 19. 26% standard heterosis. proving that N98S/ Teqing has a potential for increased yield. |
