信杂粳 1号是利用广亲和光温敏不育系培矮 64S与典型粳稻豫粳 3号配组选育而成的两系亚种间杂交粳稻组合。通过合理确定双亲播期 ,加强父本栽培管理 ,适时适量喷施“九二○” ,抓好稻粒黑粉病防治等措施 ,可有效提高制种产量。并对光温因子对制种的影响以及父母本幼穗分化特点进行了分析
Xinjingjing 1 was a cross between two lines of inter-subspecific hybrid japonica rice using a combination of Guang’ai photo-thermo-sensitive genic male sterile Pei’ai 64S and typical japonica rice Yujing 3. By reasonably determining the sowing date of parents, strengthening the management of male parent cultivation, timely spraying “九二 ○” and timely measures such as prevention and control of rice powdery mildew can effectively increase seed production. The effects of light and temperature on seed production and the differentiation characteristics of parents were also analyzed
