正文快照：: 本报讯，我校核农所，植保系科研人员经过近5年刻苦攻关，将杀虫基因成功地导入多种水稻品种中，育成了以秀水11为遗传背景的转基因新品系水稻。9月12日，这一名为“农杆菌介导法培育B.T转基因抗虫水稻研究”课题在杭州通过了专家组鉴定，为新浙大的成立献上了一份厚礼。鳞翅目昆虫二化螟、三化螟、大螟和稻纵卷叶螟等是世界水稻生产中的主要害虫。我国每年受螟虫、纵卷叶螟危害的稻田面积约1334万春顷。据测算，目前一季水稻需防治螟虫2—3次，成本10元/亩左右。如能用抗螟虫的水稻品种替代目前的推广品种，全国一年可挽回稻谷损失30亿至40亿公斤，节约生产成本50亿至60亿元，同时可免受2000万公斤农药的污染。
