Types & Availability

More than 300 varieties of watermelon are cultivated in the United States and South America, where complementary growing seasons provide a year-round supply of watermelon in an array of shapes, colors and sizes. The development of seedless varieties revolutionized the watermelon market, making this age-old fruit appealing to today’s more discriminating consumers. Because there are so many varieties, they are often grouped according to characteristics, like fruit shape, rind color or pattern, and size.

The most common watermelon types are: Seeded, Seedless, Mini, Yellow, and Orange. Learn more.

PLU/UPC

Watermelon PLUs include the following:

  • 4031 – Red Seeded Watermelon
  • 4032 – Red Seedless Watermelon
  • 4347 – Fresh Cut/Half Watermelon *Stop and Shop
  • 4340 – Yellow Seeded Watermelon

The series of PLU codes available for retailer assignment range from 4342 to 4376. They can be used to distinguish a specialty watermelon, a unique size or cut melons.

PLU codes in the PLU codes database represent conventionally grown fresh produce. To identify an organic item, the prefix of ‘9’ is inserted in front of the 4-digit conventional PLU code. There are no other existing established prefixes other than the ‘9’. Any other prefix used or length other than the standard 4-digit or 5-digit number is not part of the internationally standardized list of PLU codes for use with fresh produce. For more information, visit https://www.freshproduce.com/resources/supply-chain-management/plu-codes/.

These are UPC codes established for watermelon so far. All are for use with generic watermelon manufacturer #033383:

Yield: Using safe handling practices, as outlined by USDA, this cutting sequence resulted in the highest yield of cut fruit. Remember to wash your watermelon before cutting. 

Hollow heart three phases shown side by side

Hollow Heart

Hollow Heart is a condition that can sometimes occur in watermelon, previously thought to be as a result of disruptive weather patterns. While the internal cracking has no negative impact on the taste, quality or safety of the product, its appearance upon cutting may raise questions with customers who are not familiar with the symptom. These materials will provide you and your produce department staff with all the current scientific and regulatory information on the subject.

Recently University of Florida/IFAS Extension and the Florida Watermelon Association collected and assembled new research in a Watermelon Field Guide, a handy visual reference that growers can take to the field to identify the pests, diseases, injuries, disorders and other challenges to growing watermelon in Florida. Updated information on Hollow Heart excerpted from the Field Guide is below (based on research using seedless watermelons because the market is mostly seedless): 
Hollow Heart
Description: Hollow heart is a fruit disorder where small to large “cracks” or “gaps” in the internal tissue appear. These gaps in seedless watermelon when cut across the fruit between the stem and blossom ends typically divide the fruit into three lobes. Dense white tissue (see photo on far right) is often associated with hollow heart. Farmers sometimes refer to this white tissue as “second growth.”
Cause: Research conducted at the University of Delaware has provided evidence that links poor pollination during fruit set as the primary cause of hollow heart. Older theories, including excessively high nitrogen rates or fluctuations in irrigation, have not been proven.
Key features: In most seasons, poor pollination is much more common early, such as during the first fruit set stage. Poor pollination can be caused by lack of pollinators; however, in most years, the cause of pool pollination is due to poor weather conditions (cold, cloudy) for several days. Seedless watermelon cultivars are much more susceptible to hollow heart.
