“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。
“Two lines” hybrid rice N_ (98S) / Teqing from seedling stage began to show a variety of morphological and physiological heterosis. In terms of yield components, the average number of effective panicles per panicle (10.52%) and the number of solid particles per panicle (31.25%) showed the average superiority over the three-line hybrid rice Huayu Gui (44) Spike number (15.92%) and 1000-grain weight (5.22%) two. The theoretical yield of super-pro-11.00% advantage, competitive advantage of 19 76%. Show N_ (9AS) / Teqing have a greater yield potential.
