第二次世界大战以来,随着科学技术的发展,工业产品特别是化肥、农药等在农业上的广泛应用,耕作制度的巨大变革,研究手段的不断完善以及各门学科尤其是基础学科对育种领域的日益广泛而深入渗透,人们对于水稻育种自然规律的认识也逐渐加深,先后提出了许多适应生产和推动生产发展的新概念、新途径和新方法,使水稻育种领域更加宽阔,研究规模更加庞大,研究内容也更加丰富,出现了若干重大突破.回顾最近三十年来国际上水稻育种的基本概况,分析育种工作的主要特点,借以展望今 Since the Second World War, with the development of science and technology, the widespread application of industrial products, especially chemical fertilizers and pesticides, in agriculture, the great changes in cultivation system, the continuous improvement of research methods and the improvement of various disciplines, especially basic disciplines, The field has become more and more deeply penetrated. People’s understanding of the natural laws of rice breeding has also been gradually deepened. Many new concepts, new approaches and new methods to adapt to the production and promote the development of production have been put forward. The fields of rice breeding have become wider and the research scale has become more Huge and rich in research content, a number of major breakthroughs have taken place.Reviewing the basic situation of rice breeding in the world over the recent three decades and analyzing the main features of the breeding work, we can look forward to this
