Learn the principles and practices of plant breeding online
This course provides a foundation in the principles of genetics as applied to plant breeding. Learn about genetics, plant reproductive processes, systems of inheritance (hybridisation, mendalian genetics and more), plant breeding within the horticultural industry.
Course Aims:
- Describe the commercial and scientific nature of the modern plant breeding industry, on a global basis
- Describe the structure and function of genetic material
- Describe gamete production in plants.
- Explain the results of mono hybrid and dihybrid inheritance in plants.
- Investigate the role of systematic botany in horticulture.
- Explain a variety of different plant breeding techniques.
- Review current developments in plant breeding.
