Now a lot of vegetable seeds, will be marked with the words “do not leave seed”, why is this

Many farmers in rural areas like to keep seeds, especially when growing some vegetables, because they think it is convenient, they don’t have to worry about the quality of seeds, and they can save money on seeds. In recent years, however, they have gradually discovered that some farmers have written clearly on vegetable seed bags after use that they should not save the seeds. They are also very confused, why can’t they keep the seeds after years of growing vegetables?

Some vegetable seed packets now bear the words “No seed reserved” because the seeds of this vegetable variety are hybrids. With the development of agricultural technology, seeds of many crop varieties used in agricultural production in China now use hybrid generations.

And as far as vegetable varieties are concerned, first-generation hybrids are also widely used. As a result, farmers of many varieties are unable to save seeds. If the offspring of the first generation of hybrids are retained and used in agriculture, it will lead to severe production losses.

First, any vegetables grown by farmers who wish to continue planting next time must be the original seeds used for planting. This is because primary vegetable seeds are self-pollinated by different species of plants during flowering and pollination. Even after several generations, there is little difference between the generations.

Most vegetable seeds sold in the market are labeled as hybrid seeds. Since it is a hybrid seed, it should be propagated by pollination of the male and female parents of a pure line variety. Seeds will inherit the dominant characteristics of the background parent and the background parent. The basic purpose of cross breeding is to maximize seed resistance and improve vegetable yield and quality.

The first-generation crop hybrids are widely used in agricultural production because of the outstanding advantages of first-generation crops in yield and quality. However, the second generation hybrids are characterized by severe separation. This means that if the seeds of the first hybrids are used in agriculture, field growth will be disorderly and uneven. In addition, according to the law of plant genetics, more than 95% of isolated plants are inferior plants, and only about 0.05% of individual plants are superior to hybrid parents, which will lead to a severe reduction in yield and income. And vegetable seed also obtained patent, this also involves vegetable seed cultivation technology.

Generally, farmers have no problem growing their own seeds. However, when it comes to large-scale commercial use, this is actually an infringement. Some people don’t understand and don’t know this. But in the long run, it is beneficial to the development of agriculture and the development of Chinese vegetable seed enterprises.

There is also “cheating” for commercial gain. Although some vegetable seeds are not clearly labeled with traditional or hybrid seeds, if the words “do not save seeds” still appear at this time, farmers may be concerned that more seeds will be left behind after these seeds are sold, leading to fewer repeat customers and affecting next year’s sales plans! After all, the main purpose of such seed companies is to make money.

In fact, from another point of view, the quality of vegetable seeds is not good. I touched 25 Japanese baby squash and sweet potatoes. I know they were first planted in Weifang, Yantai and other places at that time, and they taste and look very good.

However, over the past few years, some growers have been using second and third generation seedlings, resulting in an overall deterioration in quality. In fact, not only vegetable seeds, but many seeds and even land.

Therefore, on the one hand, not keeping vegetables is for the benefit of farmers. Otherwise, if output and quality decline, a year’s effort will be wasted; On the other hand, seedless vegetables can guarantee property rights to the maximum extent and maximize the profits of seed enterprises.

To be honest, the rural economy has developed so much that there is really no need to use second-generation seeds to prevent the risk of declining yields and quality. In the process of agricultural planting, the selection of varieties is the most important step. It is very important to select disease-resistant, high-yielding and high-quality vegetable varieties. Keeping seeds is risky. Don’t be hasty.
