通过品种改良,植物育种和育种学的基本原理以往一直对粮食增产发挥着重大作用。由于过去十几年中在墨西哥、印度、巴基斯坦和其它亚洲各国采用了小麦新品种,以及通过“绿色革命”使菲律宾、印尼、印度等国获得了新的水稻品种,已经成功地、广泛地使人们认识了植物育种的作用。日本也有不少同样的情况。例如原产热带、亚热带的水稻已经向北发展到东北、北海道等寒冷地区,不应忘记,在这些成果的后面,从引种、杂交、选择到育成新品种等方面,有多少育种工作者的大量辛勤劳动。近年来,在这种常规育种技术的基础上,应用植物组织培养和细胞及分子遗传学理论与技术,逐渐形成了将为植物育种提供新技术的研究领域。本文就“细胞基因工程育种”的最近动态及其应用范围,包括作者所作展望,概要介绍如下。
Through the basic principles of variety improvement, plant breeding and breeding, it has always played a major role in increasing grain output. Thanks to the introduction of new wheat varieties in Mexico, India, Pakistan and other Asian countries in the past decade or so and the new rice varieties obtained in the Philippines, Indonesia and India through the “Green Revolution”, which have been successfully and widely used People recognize the role of plant breeding. There are many similar situations in Japan. For example, native tropical and subtropical rice has moved northward to the northeast and Hokkaido and other cold areas. We should not forget that after these achievements, there are a large number of breeding workers in terms of introduction, crossbreeding, selection and breeding of new varieties Hard work. In recent years, based on this conventional breeding technology, the application of plant tissue culture and cell and molecular genetics theory and technology has gradually formed the field of research that will provide new technologies for plant breeding. This article on the “cell genetic engineering breeding,” the recent developments and its scope of application, including the author’s prospects, summarized as follows.
