国际水稻研究所(以下简称IRRI)自六十年代建所以来,始终把培育新品种作为工作的重点。在过去的二十年培育了86个良种;同时,育种研究实践大大地丰富了水稻遗传学和育种学知识,在一定程度上改变了世界稻米研究和生产的落后状况。进入八十年代的前夕,该所的科学家们汇集一起,认真总结了二十年来的经验,并展望了今后的研究方向。现就该所的若干研究动向作一简要介绍:一、坚持早熟、高产、多抗、优质的育种目标IRRI一九六六年育成的第一个品种IR_8,具有较高的增产潜力,之后的品种选育向着多
International Rice Research Institute (IRRI) Since its establishment in the 1960s, the IRRI has always focused its efforts on cultivating new varieties. In the past two decades, 86 breeding varieties have been cultivated. Meanwhile, the practice of breeding research has greatly enriched the knowledge of rice genetics and breeding, to a certain extent, changed the backwardness of the world’s rice research and production. On the eve of the 1980s, scientists at the institute brought together two decades of experience and looked forward to future research directions. Here are some of the research trends for a brief introduction: First, adhere to precocious, high yield, multi-resistance, high quality breeding objectives IRRI Breeding 1966 IR_8, has a higher yield potential, after Breed breeding toward more
