Often meet food friends ask themselves whether the food can be planted? Why don't the seeds from your own plants grow very well? Is there any vegetable seed I can keep? ... The seeds that we use are usually bought from seed companies, and they're basically one generation hybrids. They all combine the advantages of other plants, such as high-yielding and disease-resistant cucumbers.The following content also has some reference value for raised garden beds.

We use the seeds we buy to plant vegetables and the seeds we leave behind are the second generation hybrid seeds. Then the characteristics of these seeds are divided into several kinds, such as high yield and no disease resistance, high yield and disease resistance, low yield and disease resistance, low yield and no disease resistance. If we happen to have seeds that are high yielding and disease resistant, if we happen to have seeds that are high yielding and not disease resistant or low yielding and disease resistant, especially if we have seeds that are low yielding and not disease resistant, we should cry. Even if you manage it well, it may not be as long as you want.

So back to the original question, can I keep my own food? The answer is definitely yes.

Of course, on the Internet there are also genetically modified seeds sterilized technology, left seeds can not germinate. On the one hand, the country has strict control over genetically modified seeds, and there are few genetically modified seeds in China. On the other hand, whether extinction technology (terminator gene) is allowed to be used in genetically modified seeds is very controversial. There is no reference, so this aspect will not be discussed.

You must know the specific reasons why the vegetables you planted are not always good.

So are there any seeds to keep?


I don't know if you often hear some uncles and aunts say "this is local food" when you buy vegetables as a child. What is local food?


My understanding is that it's grown from local seeds that have been passed down. Take, for example, local cucumbers. It's just been using retained seeds. Remember when we were young, the kind of corn, a lot of wheat was also sown with retained seed. And then it kind of fades away. In general, the older seeds are likely to be genetically pure seeds similar to AABB, even if hybridized, they may still be genetically pure seeds.

However, as the number of seed retention increases, due to environmental and natural hybridization reasons, the genes of seeds will also change, and gradually the relatively pure seeds that can be retained gradually disappear.

Of course, the seeds screened by hybridization also have a variety of high yield, disease resistance and other advantages, which is more advantageous. Personal advice is better not to use their own seeds to sow, after all, time consuming, if you choose a bad seed is not worth the loss.
