| 1. | Method for oryza sativa indica male sterile line maintainer line and f sub1 ; true to variety seed testing 籼型水稻不育系或杂交种与保持系种子真实性室内检验方法 |
| 2. | The results showed that the proline content of leaves from the maintainer lines were higher than those from the sterile lines 结果表明:在甜菜营养生长阶段的4个时期中,脯氨酸含量基本表现为保持系高于不育系。 |
| 3. | Fertility expression of thermo - sensitive genic male sterile genes under the backgrounds of indica cytoplasmic male sterile lines , restorer lines and maintainer lines 温敏核不育基因在籼型三系遗传背景下的育性表达 |
| 4. | Proline content of leaves from three cytoplasmic male sterile lines and their maintainer lines in sugarbeet were studied during their vegetative growth stage 摘要以甜菜3个细胞质雄性不育系及其相应保持系为材料,对营养生长阶段叶片中的脯氨酸含量进行了研究。 |
| 5. | This result also indicated that there were significant differences between maintainer lines and the sterile lines on physiological and biochemical properties during their vegetative growth stage 说明不育系和保持系在营养生长阶段生理生化代谢上已经存在差异。 |
| 6. | The average frequency of shoot regeneration in the cms line was 30 . 0 % and 2 . 34 % respectively and that in maintainer line was 30 . 0 % and 3 . 54 % respectively . on the other hand , explants of different sections of cotyledon resulted in different shoot regeneration abilities 不育系子叶与下胚轴的平均芽再生率分别为30 . 00和2 . 34 ;而保持系的平均芽再生率分别为30 . 0和3 . 54 。 |
| 7. | The male sterile lines and their respective maintainer lines of brassica napus , b . campestris and b . juncea were chosen as the parents in interspecific crosses with b . napus , b . campestris , b . juncea and eruca sativa in order to investigate male sterile cytoplasmic effects on the interspecific cross incompatibility 摘要选择甘蓝型、白菜型、芥菜型三种类型油菜雄性不育系和保持系分别与甘蓝型、白菜型、芥莱型油菜和芸芥进行种间杂交,研究十字花科种间杂交亲和性雄性不育细胞质遗传效应。 |
