Corn Flowers and Hybrid Seeds
Date of this Version
Plant and Soil Sciences eLibrary (PASSeL) Lesson
An explanation of how hybrid corn is grown and how the monoecious nature of corn is used to manipulate the cross-breeding.
1. Identify the hybrid seed producer’s job as growing the parent lines that the plant breeder has discovered to make hybrid seed that farmers would want to grow.
2. Describe how the monoecious flowers of a large number of male and female parent plants can be manipulated in a growing season in an efficient manner.
3. Predict the correct way to plant the male and female plants to insure that a farmer’s field makes the most possible hybrid seeds.
4. Outline the plant/flower manipulations that must be applied to the plants in the hybrid seed producer’s field during the growing season to produce pure hybrid seed.
