作物是栽培的植物。人类依靠绿色植物将太阳光能转变为食物中的化学能,得以生存和发展。为了让植物更好地服务于人类,有两条途径改良植物的产出,一是改良它的遗传组成,二是改良它的生长环境。改良植物遗传组成的原理、方法和技术正是本课程要讲解的内容,改良植物生长环境的方法和技术是作物栽培学的内容范畴。这门课程的主旨就是讲解如何利用DNA技术培育植物新品种,包括创造跨物种的遗传变异的基因转移育种、精确改良基因组特定位点的基因编辑育种等。学习这门课程之后,你将获得100多年来逐渐形成的作物育种的原理、方法和技术,特别是近30多年来基于DNA技术发展起来的分子育种原理和技术的知识。这些知识可用于为国家为社会为人类培育大田作物的优良新品种(像中国的袁隆平等著名育种家那样),也可以用于为自己家的庭院美化之目的培育独特的花卉蔬菜林木新品种(像英国王室的菲利普亲王那样),还可以用于辨别社会媒体舆论的正确与否,不至于人云亦云。这门课程用英语授课,受众面可以扩大到所有懂英语的本学生、研究生和植物育种工作者;本课程的课件图文并茂,知识点导图脉络清晰;本课程各单元的内容都是由研究领域最熟悉的老师授课,深入浅出,融会贯通,易学易懂。
Crops are cultivated plants. Human beings rely on green plants to convert solar energy into chemical energy in food for survival and development.In order to make plants better serve human beings, there are two ways to improve plant output: one is to improve its genetic composition, and the other is to improve its growth environment. The principles, methods and techniques of improving plant genetic composition are the contents of this course. The methods and techniques of improving plant growth environment are the contents of crop cultivation. The main purpose of this course is to explain how to use DNA technology to breed new plant varieties, including gene transfer breeding by creating cross species genetic variation, gene editing breeding by accurately improving specific genomic sites, etc. After learning this course, you will acquire the principles, methods and technologies of crop breeding gradually formed over the past 100 years, especially the knowledge of molecular breeding principles and technologies developed based on DNA technology in recent 30 years. This knowledge can be used to breed good new varieties of field crops for the country, society and mankind (like famous breeders such as Yuan Longping in China), to breed unique new varieties of flowers, vegetables and trees for the purpose of beautifying their own courtyard (like Prince Philip of the British royal family), and to distinguish whether the public opinion of social media is correct or not, Not to follow suit. This course is taught in English, and the audience can be extended to all students, postgraduates and plant breeders who understand English. The courseware of this course is rich in pictures and texts, and the guidance of knowledge points is clear. The contents of each unit of this course are taught by the most familiar teachers in the research field. They are easy to understand and learn.
