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. VAR mutations were grown over 5 weeks and height (phenotype 1) and coloration (phenotype 2) were measured. Our results showed that mutant genes in B.rapa affected the growth and coloration of the plant. This demonstrated a difference between the plant height and coloration in B.rapa mutants and wild type plants. The wild type plants were visibly taller and had a lower percentage of variegated leaves compared to the mutant plants.
