摘  要:
以带有明显淡绿叶标记性状 (pgl基因 ,位于第 1 0条染色体上 )的光 温敏型核不育水稻M 2S为供体 (父本 ) ,以优质早籼保持系中红B为母本杂交 ,再用其F1为母本同珍汕 97B杂交获得三交种 ,F2 选择带明显淡绿叶标记性状的高结实率、综合性状好的材料作为保持系选材加代到F4,F4株系分单株与珍汕 97A测交选择能保持完全不育的保持系 ,进一步回交 ,从而得到株叶型整齐一致、不育性稳定、性状优良的带有明显淡绿叶标记性状的不育系—标 1A。标 1A与中 41 3、明恢6 3配组表现出较强的杂种优势。标 1A无论是在不育系繁种、杂交稻制种还是在大田生产上 ,在苗期就能很容易分辩出真伪种 ,从而能有效减少不必要的损失

摘  要:
A photo thermo sensitive genic male sterile line M2S carrying plg gene(light green leaf)was used as marker donor to develop a morphological marker cytoplasmic male sterility(CMS)line.The hybrid F1 between Zhonghong B and M2S was crossed as female parent with Zhenshan 97B.The plants with high fertility and better agronomic traits as well as light green leaf were selected in following generations.A total of 120 breeding lines were identified in F4 generation and crossed as father parent with a CMS line Zhanshan 97A.After three backcrosses,a new CMS line Biao 1A with pgl gene was developed.Biao 1A has good agronomic traits,stable sterility and excellent flowering habits.The hybrid F1 between Biao 1A and Zhong 413 or Minhui 63 showed strong heterosis.
