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. Rosette Dwarf mutants and standard plants were grown over 4 weeks and plant height and number of leaves were measured. The hypothesis was supported for plant height as Rosette dwarf plants grew significantly shorter than wild type plants (p value= 7.8x10^-16). On the other hand, the hypothesis for the number of leaves was not supported because there was no significant difference between the average number of leaves grown in Rosette Dwarf and Wild Type variations of Brassica rapa.
