Watermelons

Types of Watermelon

About 200-300 varieties are grown in the U.S. and Mexico, although there are about 50 varieties that are very popular.  The modern watermelon lover sees his or her watermelon options as these five types: Seeded, Seedless, Mini, Yellow and Orange.

Where do Seedless Watermelons Come From?

Seedless WatermelonSeedless watermelons were invented over 50 years ago, and they have few or no seeds. When we say seeds, we are talking about mature seeds, the black ones. Oftentimes, the white seed coats where a seed did not mature are assumed to be seeds. But this isn’t the case! They are perfectly safe to swallow while eating, and don’t worry – no seeds will grow in your stomach.

So, how are seedless watermelons grown? Chromosomes are the building blocks that give characteristics, or traits, to living things including plants and watermelons. Watermelon breeders discovered that crossing a diploid plant (bearing the standard two sets of chromosomes) with a tetraploid plant (having four sets of chromosomes) results in a fruit that produces a triploid seed. (Yes, it has three sets of chromosomes). This triploid seed is the seed that produces seedless watermelons!

In other words, a seedless watermelon is a sterile hybrid which is created by crossing male pollen for a watermelon, containing 22 chromosomes per cell, with a female watermelon flower with 44 chromosomes per cell. When this seeded fruit matures, the small, white seed coats inside contain 33 chromosomes, rendering it sterile and incapable of producing seeds. This is similar to the mule, produced by crossing a horse with a donkey. This process does not involve genetic modification.

How to pick a good Watermelon

  1. Look the watermelon over.
    You are looking for a firm, symmetrical watermelon that is free from bruises, cuts or dents.
  2. Lift it up.
    The watermelon should be heavy for it’s size. Watermelon is 92% water, most of the weight is water.
  3. Turn it over.
    The underside of the watermelon should have a creamy yellow spot from where it sat on the ground and ripened in the sun.

Washing that Watermelon

This is true for all fruits and veggies, rinds or not! You should also use clean knives and cutting surfaces, and make sure you have washed your hands prior to preparing the watermelon for eating.
