Watermelon n Watermelon's botanical name is Citrullus lanatus of the botanical family Curcurbitaceae. It is a cousin to cucumbers, pumpkins and squash. n Watermelons are "vine crops" with spreading growth habits the crops of this family prefer hot and humid weather as is found in the southern United States. n Watermelons need an average of 4 months to mature, from 80 to 120 days. A loose, sandy loam soil is preferred. n The watermelon is comprised of about 90% water, approximately 4 gallons for a forty pound melon. Water supply is critical during the growth and development of the plant and fruit. Water shortages will cause noticeable gaps in production with a reduction in leaf area and overall yield.

Watermelon Varieties About 200 -300 varieties are grown in the U. S. and Mexico, although there about 50 varieties that are very popular. The following are the four varieties you will most likely see at your local store.

Seedless Watermelons n How are seedless watermelons made? Where does a plant without a seed come from? The answer is in the number of chromosomes. A normal watermelon plant’s chromosomes are doubled by the use of the chemical colchicine. Doubling a normal (diploid) watermelon results in a tetraploid plant (one having four sets of chromosomes). When the tetraploid plant is bred back, or pollinated, by a diploid or normal plant, the resulting seed produces a triploid plant. The seeds/plants have three chromosomes and cannot reproduce. Seed of seedless varieties are available from most major seed companies.
