Abstract
Brassica rapa is a small flowering plant that is often used in classroom experiments due to its small size, low-maintenance growing conditions, and quick life cycle. Several mutant lines have been bred and briefly described, although not much is known about the actual genetic changes and therefore all the downstream effects of that mutation. Nine different mutant lines of Brassica rapa were grown to more carefully identify the phenotypes affected by the mutations. One mutant is the petite B. rapa (dwf/dwf), which is often characterized by shorter stems, smaller leaves, and darker green color. Petite B. rapa (dwf/dwf) were grown over 4 weeks and plant height and mass of the reproductive system were measured. There was no observable difference in the height of the petite B. rapa (dwf/dwf) and wild-type B. rapa. There was no statistically significant difference between the flower mass of the petite B. rapa (dwf/dwf) and wild-type B. rapa.
