If you are negligent in selecting a high quality fruit for its seeds, the resulting tomato plant will also suffer in quality.
Below are a few key components to look for when selecting the right tomato for its seeds: • Be certain that you extract seeds from an open-pollinated, rather than a hybrid, tomato.
• Make sure the tomatoes you select are fully ripe.
Seeds from an overly ripe tomato could already be on their way to germinating or even accumulating mold growth • Save seeds from the best-looking, best-tasting fruits on the plant.
When you save from the very best, the resulting plants will be predisposed to having those same desired attributes.
• It's fine to save seed from plants that have suffered from blight or one of the many wilt that affect tomato plants.
Slice the tomato across its exact middle.
Slicing will facilitate squeezing out the seeds more effortlessly in the next step.
Gently squeeze the seeds and their adjoining membrane into a plastic or glass container.
Pour 2-3 cups of water over the seeds.
It's important to label your container so you don't forget which variety of tomato seed you've saved.
Let it sit for two to three days, until you see white mold growing on top of the water.
This is a sign that the membrane around the seeds has begun to break down.
Pour away the mold and as much of the water as you can, including any seeds that happen to be floating.
Seeds that are floating are considered "bad" and they will not germinate at the time of planting.
Make sure you rinse the seeds a few times, while pouring off the water and any seeds or excess material that may be floating.
Then gently pour the seeds through a very fine mesh strainer and rinse well, using your fingers to remove any membrane that is still stuck to the seeds.
Label a paper plate with the tomato variety, and place your seeds on it.
Be sure that the seeds are in a single layer so they dry well and do not mold.
Set the labeled plate aside for a few days so that the seeds dry out fully.
Once there are dry, put the seeds in a container and label them as you don't want to mix them with other seeds type.
It makes life easy and the selection better when the time comes for planting.
