| Abstract: | The upland rice variety 'Huhan 3',a drought-resistant donor,was crossed with 'Hanfeng B' and then continuously backcrossed.The segregating generations were screened under water stress according to drought resistance and selected in normal paddy field according to yield performance, and thus a water-saving and drought-resistant sterile line 'Huhan 2A' and its maintainer line 'Huhan 2B' were bred. |
