The curious case of white sweet corn: solving the enigma of its color

Sweet corn, a beloved summer treat, is a staple in cuisines worldwide. However, one question that often arises is: why is sweet corn white? The answer lies within the complex genetic makeup of this delectable vegetable.

Pigmentation and Genetics

The color of sweet corn is determined by a specific gene called the Y1 gene. This gene controls the production of carotenoids, pigments responsible for the yellow color in many fruits and vegetables. In white sweet corn, a mutation in the Y1 gene results in the absence of carotenoid production, leading to the characteristic white kernels.

Historical Evolution of White Sweet Corn

The origin of white sweet corn can be traced back to the 19th century. In 1848, a farmer named Aaron Perry crossed a yellow sweet corn variety with a white flint corn variety. The resulting hybrid exhibited white kernels with a sweeter flavor than its predecessors. This hybrid became known as “Perry’s Hybrid,” and it eventually gave rise to the modern-day white sweet corn varieties we enjoy today.
