Studies on the Feasibility of Multi-advantage Integration from the Rice Variety Suijing No.5

用丰产、抗病、优质的藤系 137为母本与抗盐碱、耐冷凉、抗倒伏、熟期早的绥粳 1号为父本进行杂交 ,聚集亲本优良性状 ,去其不良性状 ,经过田间系统选育、特性鉴定与室内考种 ,育成了集丰产、优质、抗盐碱、耐冷凉、抗病、抗倒伏、早熟于一体的多优集成新品种绥粳 5号。

By sexual hybridation, the female parent-tengxi 137 with high yield, disease resistance and high quality crossed with male parent Suijing No.1 with saline-alkali and cold resistamce. We developed a multi-advantage integration new rice variety suijing No.5 which gathered parents advantages.
