N5047_s是1980以HPGMR农垦58_s为不育基因供体,与中粳品种“中黎”杂交,经过多代连续选择而成,具有不育性稳定,育性转换明显,开花习性较好,可育阶段自交结实率高,抗稻瘟和白叶枯病等特点。用N5047_s与R9-1配制的组合,经三年的大面积示范,一般每亩比鄂宜105等常规粳稻增产50～70公斤,与晚籼杂产量相近,成为第一个应用于生产的两系法杂交粳稻组合。 N5047_s was a hybrid of HPGMR cultivar 58_s as a sterile gene in 1980 and a medium japonica variety “Zhongli”. After several generations of continuous selection, N5047_s had stable sterility, obvious fertility transformation, good flowering habit and fertility Self-self-solid stage, resistant to rice blast and bacterial blight and other characteristics. With the combination of N5047_s and R9-1, after three years of large-scale demonstration, the conventional yield of conventional japonica rice per mu is higher than that of Ezhou 105 by 50-70 kg, which is similar to that of late indica hybrid rice and became the first two Method of Japonica Hybrid Rice Combination.
