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. Variegated Brassica rapa were grown over 4 weeks and total variegation (phenotype 1) and height (phenotype 2) were measured. After the final week we found that variegated plants showed significantly more variegation in the leaves compared to the wild type. Although the wild type Brassica rapa were found to have a significantly greater height of inflorescence compared to the variegated Brassica rapa. There was no significant difference in total height between the variegated and wild type Brassica rapa until day 21.
