| 1. | Comparison on some aspects of photosynthetic declination of wild rice and cultivated rices 普通野生稻和栽培稻光合功能衰退的比较 |
| 2. | A preliminary investigation of the genetic variousness of the common wild rice resources in guangxi 普通野生稻遗传多样性保护技术探讨 |
| 3. | Comparison of the genetic diversity of common wild rice and cultivated rice using ssr markers 标记比较亚洲栽培稻与普通野生稻的遗传多样性 |
| 4. | Study on the transfer of the brown leafhopper - resistant genes from common wild rice o . sativa to cultivated rice 普通野生稻抗褐稻虱基因导入栽培稻研究 |
| 5. | Studies on evaluation of the genetic diversity of core collection of common wild rice oryza rufipogon griff . and asian cultivated rice oryza sativa l 普通野生稻和亚洲栽培稻核心种质遗传多样性的检测研究 |
| 6. | ( 3 ) under side by side plantation , the frequency of gene flow from cultivated rice to common wild rice was found to be 2 . 162 % - 7 . 598 % , indicating there exists a relatively high degree of genetic change between them under natural conditions 在自然条件下,两种普通野生稻与转基因水稻l201相邻种植( 0m区) ,在o rufipogon上检测到的基因漂流频率达7 . 598 % ,在o nivara上检测到的基因漂流频率为2 . 162 % ,说明栽培稻与普通野生稻之间有相当高的基因漂流。 |
| 7. | 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。 |
| 8. | Based on data generated , we classify 8 recipients into three categories in terms of possible environmental impact : ( 1 ) low risk of gene flow to common cultivars ; ( 2 ) intermediate risk to common wild rice with same aa genome ; ( 3 ) high risk to ms lines . 2 . development of a specific database for toxin and anti - nutrient proteins bioinformatics is a very useful tool for risk assessment of gm foods 从转基因水稻的环境风险考虑,转基因向常规稻的基因漂流频率及最大距离都较小,相应地其风险也较低;向不育系的基因漂流频率较高,最大漂流距离也较大,相应地其风险也较高,应重点考虑转基因漂流对杂交稻制种纯度的影响及其可能引起的环境风险后果;转基因向普通野生稻的基因漂流频率中等。 |
