![]() Seed of seedless varieties are available from most major seed companies. When the tetraploid plant is bred back, or pollinated, by a diploid or normal plant, the resulting seed produces a triploid plant that is basically a "mule" of the plant kingdom, and it produces seedless watermelons. Doubling a normal (diploid) watermelon results in a tetraploid plant (one having four sets of chromosomes). So, where do the seeds come from? Simply stated, the number of chromosomes (the threadlike bodies within cells that contain the inheritance units called genes) in a normal watermelon plant is doubled by the use of the chemical colchicine. ![]() The obvious question asked about growing seedless watermelons is: "How does one obtain seed of a seedless watermelon?" Obviously, you cannot save seed from a seedless watermelon. Seedless watermelons-sweet inside but without the numerous seeds found in conventional watermelons-are the ultimate in convenience foods. The seedless watermelon is now a reality. This article is excerpted from "Seedless Watermelon Production" by Jerry Parsons, Larry Stein, Tom Longbrake, Sam Cotner, and Jerral Johnson, published by the Texas Agricultural Extension Service. Us this release is unacceptable to you, then you must not If you can direct seed into the garden, rather than starting seedlings in the greenhouse, you should.īy purchasing our watermelon seed, you hereby release us fromĪny and all liability for Watermelon Fruit Blotch Disease , We have talked to many watermelon seed producers and it appears that this disease is almost always found from transplants grown in warm, humid greenhouses. Our seeds are from growers who have tested for this disease by growing isolation lots from seeds and inspecting for the disease, which is the only known way to test seeds for the disease at this time. Too date, their is no way to prove if this disease is present in seeds, and their are many other possible sources for ![]() Research has shown that the early detection of the disease, followed with timely applications of copper based fungicides, can greatly reduce the spread and subsequent damage caused by the disease. While Bacterial Fruit Blotch can be a devastating disease, early detection can help minimize losses. The fruit will begin to decay and make it unmarketable. However, the real damage from this disease occurs after fruit set, when these lesions appear on the fruit. They will change, turn nektonic with yellow halos around the necrosis, possibly appearing on the leaves during any stage of plant growth. In young seedlings, the disease can cause water soaked lesions to appear on the leaves of the plant, and in some cases on the stem as well. The most pronounced spread of Bacterial Fruit Blotch occurs in greenhouses, where optimal conditions for the spread of the disease occur. This bacteria may be seed borne, but infection may also occur from many types of secondary sources before or after planting. The causal organism of Bacterial Fruit Blotch is Acidovorax Avenae Subs Citrulli.
