摘要杂交水稻经历了由三系杂交稻、两系杂交稻到超级杂交稻的发展历程，取得了一系列重大科技成果，对中国乃至世界的粮食安全做出了巨大贡献。 |
| 9. | The experiment was conducted in a 2 . 4 ha isolated field mimic rice production practice with pollen competition . a japonica gm rice l201 containing bar gene with herbicide basta resistance was used as a pollen donor and six indica hybrid rice varieties and its male sterile ( ms ) lines and two common wild rice ( oryza rufipogon and o . nivara ) that share same aa genome with cultivated rice were used as recipients
本试验选择广州作为华南水稻生态区的代表，以含bar基因(抗除草剂basta )的转基因粳稻l201为花粉供体，模拟大田生产实际，对转基因向籼型两系及三系杂交稻不育系、杂交稻品种及含aa基因组的普通野生稻的基因漂流及其影响因素进行了研究。 |
| 10. | These restorer lines showed both stable and uniform agronomical characters and a good restoring ability , and their testcrossing f1 hybrids had a strong heterosis in grain yield , which indicates that the recurrent selection provides an effective way in breeding of three - line japonica restorer lines and makes it possible the commercial production of three - line japonica hybrid rice in north cold rice growing area in china
这些恢复系性状稳定，恢复度好，测交f1代产量优势明显，表明轮回选择为粳稻恢复系选育提供了一条新的技术途径，并使三系杂交稻在北方寒冷稻作区的大面积推广成为可能。 |
