摘要
挖掘利用地方稻种资源,利用贵州高原粳稻与矮秆籼稻杂交改良,经过2次杂交(纳雍大红谷/南京11//8902S),多代单株选择,育成耐寒保持材料95F076,用其与野败胞质不育系珍汕97A杂交,再连续8代回交,育成新不育系G98A。
G98A, a new rice sterile line, was bred from Zhenshan 97A (a CMS line) × 95F076 [a maintainer line bred from Nanjing 11(a convetional indica variety) × Nayongdahonggu (a local japonica variety) × 8902S (a nuclear sterile line) ] after eight genenations continuously.
