生物技术已经影响到人类生存的各个领域,在农业上,为了尽快获得符合育种目标的新品种,育种家将生物技术与常规育种技术密切结合,进而带来育种水平的提高、创新和突破。从细胞工程、染色体工程、基因工程及分子标记技术四个方面概述了生物技术在玉米育种中的应用概况,综述和追踪了其最新研究进展,总结了各个方面仍然面临的问题。 Biotechnology has affected all areas of human existence. In agriculture, in order to obtain new varieties that meet the breeding objectives as soon as possible, breeders will closely integrate biotechnology with conventional breeding techniques, thereby bringing about improvements in breeding, innovation and breakthroughs. This paper summarizes the application of biotechnology in maize breeding from four aspects of cell engineering, chromosome engineering, genetic engineering and molecular marker technology. It summarizes and tracks the latest research progress and summarizes the problems that various aspects are still facing.
