Lesson Objectives1. A hybrid seed producer will grow the parent lines that the plant breeder has discovered to make hybrid seed that farmers would want to grow.
2. Large numbers of plants from the lines that are to be the male and female parents can be manipulated in a growing season in an efficient manner because corn has monoecious flowers.
3. Planting the male and female in the correct way can insure that a farmer’s field makes the most possible hybrid seed.
4. The several plant/flower manipulations must be applied to the plants in the hybrid seed producer’s field during the growing season to produce pure hybrid seed.
