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. Non-purple, yellow-green (NPYG) were grown over 4 weeks and height and color were measured. It was hypothesized that the color of the NPYG will be a lighter yellowish-green color than the standard Brassica rapa while the height will increase in the NPYG compared to the standard Brassica rapa due to the lack of Anthocyanin. The data showed that there was no statistically significant difference between the height of the mutant (NPYG) and the standard Brassica rapa. However, the data showed that there was a difference in color between the standard and NPYG Brassica rapa. It was found that the NPYG was a lighter yellow green for both its true leaves and cotyledons.
