根据粳型光敏核不育系Ｎ５０８８Ｓ“一系两用”的特点，把Ｎ５０８８Ｓ的原种生产程序定为“三圃一田法”（即单株选择圃、分系鉴定圃、混系繁殖圃及原种生产田）．并采用“缩短母本繁殖代数、选择好母本繁殖田、严格操作”等措施防杂保纯，使Ｎ５０８８Ｓ种子纯度始终保持在９９．５％以上。 According to the characteristics of Japonica type photo-sensitive genic male sterile line N5088S “a series of dual-use”, the original production process of N5088S is defined as “three nursery one field method” (ie single plant selection, branch identification, mixed breeding) And the original production field). And adopt “shorten the maternal breeding algebra, choose a good maternal breeding field, strict operation” and other measures to prevent impurity Bao pure, so that the purity of the N5088S seed remained above 99.5%.
