自1955年以来的20年间,从日本遗传育种的研究趋向来看,仍以稻麦材料作为研究中心。方法方面,在导入和发展群体遗传学、生统遗传学的基础上,出现了计量育种,此外抗病育种、利用原子能和化学物质的诱变育种以及细胞染色体工程学育种都正活跃地展开,同时分子遗传学的技术也已引入到育种工作中来。由于集团选择法的采用,目前正在探索加速水稻世代的方法,最近在需要多年才能稳定的、通过种属间杂交所进行的抗赤霉病小麦的育种中,已研究了加速小麦世代的技术,一年中可繁殖4.5～6代。1950年在新设的东北农业试验场麦类霉病研究室
In the 20 years since 1955, from the research trend of Japanese genetics and breeding, rice and wheat materials are still the research centers. In the aspect of methods, based on the introduction and development of population genetics and ubiquitous genetics, metrology breeding has appeared. In addition, disease-resistant breeding, mutation breeding using atomic energy and chemical substances, and cell chromosome engineering breeding are all actively carried out. At the same time, molecular genetics techniques have also been introduced into breeding work. Due to the adoption of the Group Selection Act, methods to accelerate rice generation are currently being explored and the technology to accelerate wheat generations has recently been studied in breeding of scab-resistant wheat through interspecific hybrids that has taken years to stabilize, A year can breed 4.5 to 6 generations. 1950 in the new Northeast Agricultural Experimental Field wheat mold fungi laboratory
