继杂交水稻、玉米之后,陕西农垦科教中心研究员李殿荣,用近30年心血,换回了世界上第一个投入大面积使用的杂交油菜品种“秦油二号”,令世界刮目!目前这一油菜品种,已推广到全国十多个省、区,种植面积占油菜种植总面积的四分之一。比寻常品种可增产30％左右,每亩净增菜籽30公斤以上,最高产量可近400公斤,仅今年增加社会效益就达8亿元。 在1991年加拿大世界第八届杂交油菜学术研讨会上,当我国专家宣布这项成果时,引起震动。为此进行大量投入、多年艰苦努力的澳大利亚、美国等专家、学者,无不感到诧异。世界著名育种专家、加拿大道奈博士声称:“秦油二号的成功,展现了油菜杂交优势利用的广阔前景。” 与动物杂交不同,象水稻、小麦、油菜等农作物,雄雌同花,要实现杂交育种,首先必须有雄性不育的植株,育种学上叫做“雄性不育系”;还要有使雄性不育系产生后代,而且后代也是雄性不育的“保持系”;再下来还要有与不育系杂交的“恢复系”。三系配套 Following the hybrid rice, corn, Shaanxi Land Reclamation Science and Technology Research Fellow Li Dianrong, with nearly 30 years of hard work, in exchange for the world’s first large-scale use of hybrid rapeseed varieties “Qinyou II” make the world scratch! The current Rape varieties, has been extended to more than a dozen provinces, autonomous regions, planted area of ​​rapeseed planting a quarter of the total area. Than ordinary varieties can increase about 30%, a net increase of more than 30 kg rapeseed per mu, the highest yield of nearly 400 kg, only this year increased social benefits reached 800 million yuan. At the 8th Canadian Hybrid Rape Symposium in 1991, when our experts announced the result, they were shocked. Many experts and scholars from Australia, the United States and other countries who have invested heavily in this effort and worked hard for many years are all surprised. World-renowned breeding expert, Dr. Dawn of Canada, said: “The success of Qinyou II demonstrates the bright future of rape hybridization.” Unlike hybrids of animals, such as rice, wheat, rapeseed and other crops, To achieve hybrid breeding, we must first have male sterile plants, breeding is called “male sterile line”; also have to make male sterile lines produce offspring, but also offspring of male sterility, “keep the line”; Have a hybrid with the sterile line “restore system.” Three series of matching
