This page summarizes a learning activity, developed in part by SolCAP, that is found in the Plant and Soil Sciences eLibrary as well as here. It discusses the basic process used in a traditional breeding program. Crossing, genetic variation, selection, and elements of DNA technology are discussed within this activity. The material is aimed towards high school or introductory life science undergraduate students.

Introduction

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.
