The plant breeding process requires a number of steps and a total of 10-12 generations to complete. An interactive animation has been created to help you/your students understand the general steps involved. At the completion of this activity you/your students should be able to:
- State the expected number of years it takes to develop a cultivar in traditional breeding programs and explain why it takes that long.
- Define the terms homozygous and heterozygous.
- Define the terms genotype and phenotype.
- Explain what molecular markers are and how they are used in a traditional breeding program.
- Identify the point in the breeding program during which the breeder works with the most genotypic variation.
- Identify the point in the breeding program during which the breeder plants lines in the most locations.
- Explain how and when genetic engineering can work in conjunction with traditional breeding.
