The invention of agriculture, 10 000 years ago, heralded the dawn of civilization. The constant improvements in technology and crop productivity through selection and breeding of plants have contributed to the growth of human civilization. Bearing in mind that there are natural limits to increased productivity by environmental manipulations, one way to improve and maintain a sustainable level of crop productivity is through the exploitation of biotechnology. Indeed, one major aim of biotechnology is to increase yield, while maintaining stable human ecosystem. Plant biotechnology and molecular breeding have already proved their impact in enhancing the productivity of some of the major agricultural crops. They will continue to contribute to the production of plants with novel traits that are otherwise difficult or impossible to develop by conventional breeding. In an age in which the dynamic field of plant biotechnology advances at an accelerating rate, there is a growing need to explain how that science is applied. After completion of the course the students will: • have a basic knowledge of biotechnology; • be able to perform biotechnological experiments on plants and evaluate the • have good knowledge about application of plant tissue culture techniques in • obtain certain practical training in methods used in plant biotechnology.
