Genetic Mutation

Definition - What does Genetic Mutation mean?

A genetic mutation is an unexpected sudden change in the plant’s genetic makeup (DNA) and structure that is not related to the plant’s ancestry. Genetic mutations are linked to over-exposure to ultraviolet radiation or chemicals.

MaximumYield explains Genetic Mutation

Radiation breeding to induce a genetic mutation was first discovered in the 1920s by Lewis Stadler at the University of Missouri. This botanist used a dose of x-rays on barley and maize. As a result of a genetic mutation, the barley produced pale yellow, white, and yellow plants with white stripes.

Atomic gardens are often favored for genetic mutation and radiation breeding. Scientists have also sent seeds into orbit around the earth to expose them to more powerful doses of radiation. Some genetic mutations are harmful, while others are encouraged to help the plant produce better-quality crops.
