Obtain Your Own Seeds of Open-Pollinating Varieties

New hybrid varieties (F1) cannot be propagated from their own seeds; they lose more of their original characteristics with each generation. However, you can obtain your own seeds from old, seed-resistant zucchini varieties. So if you want to obtain your own seeds from a particularly high-yielding variety, you should only Grow a Open-Pollinated Plants in your garden. The variety 'Cocozelle di Tripolis' is a seed-resistant zucchini variety that is very popular with many hobby gardeners.

Cucurbits like to cross-pollinate with each other, which means that the varieties mix. To prevent this, you can keep a sufficient distance from the next pumpkin plant or use an isolation tunnel. Otherwise, you risk taking seeds that produce inedible and even poisonous fruit. Therefore, avoid growing zucchinis and pumpkins at the same time, especially ornamental pumpkins in the same season. Otherwise, the variety may lose its specific characteristics when crossed. It can also lead to increased storage of the bitter substance cucurbitacin. This not only makes the fruit inedible, but also poisonous. The original zucchini varieties produced cucurbitacin as a natural protection against being eaten. In more recent varieties, the bitter substance has been bred out.

And This Is How the Seed Harvest Works:

To do this, the seeds are scraped out of a properly ripened fruit together with the pulp and placed in a bowl of lukewarm water. After a few days, the mixture begins to ferment and the pulp dissolves. The seeds are then washed in a coarse sieve and laid out to dry. When drying, make absolutely sure that the seeds are completely dry, otherwise they will go moldy later. Seeds should generally never be dried in the sun, as this weakens their germination capacity.
