21世纪,农业生物技术将是农业科学以及农作物品种改良研究的带头学科。农业生物技术发展很快,植物细胞器培养,已培育出小麦、玉米、水稻等作物新品种,无性繁殖亦在科研、生产上达到普及程度。植物原生质体培养,既使难度很大的禾本科作物如水稻、小麦、玉米,双子叶植物如棉花、大豆等,都获得了再生植株。原生质体融合首先在烟草上取得突破,随之主要粮食作物均有建树。植物外 In the 21st century, agricultural biotechnology will be the leading discipline in agricultural science and crop variety improvement. Rapid development of agricultural biotechnology, plant cell organelles have been cultivated, wheat, corn, rice and other crops have been breed new varieties, asexual reproduction also in scientific research, production reached popularity. Plant protoplast culture, even if the difficulty of grasses such as rice, wheat, corn, dicotyledons such as cotton, soybean, etc., have been regenerated plants. Protoplast fusion first made a breakthrough on tobacco, followed by major food crops have been built. Outside the plant
