We used a novel approach that combined direct PCR of plant tissue and SRAP DNA fingerprinting to seek to identify the crosses made in "Brassica rapa" used in the Wisconsin Fast Plants. Our goal was to develop a rapid method for students to use in a biology, botany, or genetics class to identify the parental types (purple stem, non-purple stem) and the F1 generation for "Brassica rapa." Our data indicates that there is detectable polymorphism in the "Brassica Rapa" plants with which to identify the three types of plants.
