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. Purple stem hairy Brassica rapa were grown over 4 weeks and anthocyanin production and above ground biomass were measured. Our hypothesis that purple stem hairy Brassica rapa produced more anthocyanin was supported. However, the purple stem hairy Brassica rapa had a significantly smaller biomass compared to the wildtype Brassica rapa. This indicates that more anthocyanin production can decrease the above-ground biomass in Brassica rapa.
