Avid gardeners may be able to create new and exciting hybrids in their own backyards. As exciting as the process might be, you should keep in mind that many varieties are hybrids, and the seed from these will be unpredictable. The original hybrids are derived from a controlled cross between two selected parents. Seeds saved from these hybrids often do not resemble either parent, and are often inferior in quality. Anther drawback of this technique is that some vegetables do not breed true to seed.
Potatoes are a good example.
This is primarily why potatoes are grown from tubers rather than seed. The small balls that form at the top of the plants contain thousands of seeds. If collected when mature and planted, the seeds will produce potatoes. Unfortunately, the resulting plants are exceeding variable in color, shape and quality. Thoroughly dry the seed to prevent premature death of the seed and to ensure proper storage until spring.
