以开发水稻种质资源为重点的日本作物育种工作,一年来成绩显著。1984年农林省属下的科研机构育出一种杂交水稻新品种F_1代,试种后的产量比现有高产品种的产量要高13%,这是日本第一个专利注册的杂交水稻。此外,日本KIRIN·BREWERY公司最近和美国加利福尼亚州植物遗传公司合作培育出“合成种子”,这种新一代的植物的整个生育期要比同类植物短,不经受精过程就能结籽成熟。85年年初,位于东京郊外的某一国立生物实验室成功地把菜豆蛋白质遗传物质转导到烟草和茄科植物细胞中,从而有可能使烟草类作物在近期内成为人类的一种食物新来源。目前由农林省引头,联合各有
The Japanese crop breeding work focusing on the development of rice germplasm resources has achieved remarkable results over the past year. In 1984, research institutes under the Ministry of Agriculture, Forestry and Forestry held a F_1 generation of new hybrid rice varieties. The yield after the trial planting was 13% higher than that of the existing high-yielding varieties. This is the first patent-registered hybrid rice in Japan. In addition, KIRIN · BREWERY, a Japanese company, recently partnered with Plant Genetics Inc. of California, USA, to breed “synthetic seeds” that are shorter in their entire growing period than their counterparts and capable of maturing without being fertilized. In early 85, a National Laboratory of Biology located on the outskirts of Tokyo successfully introduced kidney bean protein genetic material into tobacco and Solanaceous plant cells, making it possible for tobacco crops to become a new source of human food in the near future . At present, the Agriculture and Forestry Department, the United have their own
