摘要/Abstract

摘要： 为评估抗草铵膦转基因水稻明恢86B大规模推广后演化为杂草的生态风险，在农田生态环境下比较了明恢86B、明恢86和杂交稻组合汕优63的生存竞争能力、繁育能力、落粒性、种子生存能力以及对常规除草剂氟吡磺隆的耐药性。结果表明，无论在适宜季节还是非适宜季节，明恢86B和明恢86的生存竞争能力和繁殖力都低于杂交稻组合汕优63，尤其在非适宜期时，汕优63的生存竞争力、繁殖力明显强于明恢86B和明恢86。主要表现在植株较高、分蘖较多以及高产。明恢86B的生存竞争力和繁殖力都略低于明恢86。3个材料的落粒性都不强，且尚未见自生苗产生。在浅埋和深埋处理下，明恢86B种子的生存能力弱于汕优63和明恢86。3个材料对除草剂氟吡磺隆的耐药性无明显差异。表明抗草铵膦转基因水稻86B在中国南京地区环境条件下演化为杂草的可能性较小。

Abstract: To evaluate potential environment safety for release of transgenic rice Minghui 86B, the potential ecological risk of weediness of transgenic glufosinateresistant rice Minghui 86B was assessed. The surviving and reproduction ability，seed shattering, seed viability of transgenic glufosinateresistant rice Minghui 86B, Minghui 86 and hybrid rice Shanyou 63 were comparatively evaluated in field, as well as their tolerance to flucetosulfuron in greenhouse. The surviving and reproducing abilities of Minghui 86B and Minghui 86 were lower than that of Shanyou 63 both in the appropriate season and in the unfavorable season, especially in the latter. The surviving ability of Minghui 86B was lower than that of Minghui 86. The seed shattering of the three rice materials were weak, and no volunteer seedlings were found. After shallow and deep buried, the seed viability of transgenic rice was weaker than those of Shanyou 63 and Minghui 86. The tolerance of the three rice materials to herbicides flucetosulfuron was similar. It is concluded that potential weediness of the transgenic glufosinateresistant rice Minghui 86B, was low in Nanjing, China.
