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. The petite mutant was carefully looked into in comparison to the wild type of B. rapa. The growth rate and flowering rate was measured at 21 days old in order to determine the effects of the genetic changes in the petite mutant. On average, it was statistically significant that the petite B. rapa were smaller and the flowering was less than the Wild Type. It was concluded that the petite plants were shorter through our experimental processes.
