It is not impossible to leave seeds for wheat, but it is not recommended to leave seeds.

Abstract: there are risks in keeping seeds, wheat planting season, it is recommended to purchase new seeds.

Is it possible to keep wheat seeds? A word of advice on promoting agriculture through science: please be careful! The reason for saying this has a lot to do with the pollination system of wheat! And if a friend asks if corn can be planted, science can clearly say: no! Although there is a risk of yield reduction for wheat inbred seeds, this risk is much lower than that of corn, and if farmers can strictly follow the advice of scientific development of agriculture to carry out special seed breeding areas for seed production, such seeds will be more secure. But for wheat hybrids, there is still no seed left. Next, the scientific development of agriculture will introduce the issues related to the retention of wheat seeds.

Wheat hybrids are not allowed to remain

At present, the Institute of Science and Technology of Chinese Academy of Agricultural Sciences has realized three-line wheat breeding, and there are related hybrids in the market. For this kind of hybrids, if seed retention is carried out, there will be separation of hybrid characters, and there will generally be a substantial reduction in yield compared with hybrid corn, so for hybrids, even if farmers have good seed production conditions and techniques, they are also unable to produce seeds, even more unable to retain seeds. To put it bluntly, the risk of reducing production is too high.

Wheat inbred seed

Wheat has a strict self-pollination system, so the most wheat varieties we have seen are also self-pollinated, and it is precisely because of wheat self-pollination that the rate of variety degradation is much lower than that of other crops. The root cause of variety degradation is also caused by the mixing of external farmland pollen introduced by bees or insects. Therefore, if farmers want to retain the seeds of self-bred wheat, scientific agriculture suggests: draw a small area in the middle of the farmland for isolation and protection, harvest and store separately, avoid being introduced by other wheat varieties or foreign pollen, and maintain the purity of the original wheat varieties as much as possible. In this way, even if the seed is left, the rate of variety degradation is much lower. At the same time, if you can select the best when keeping the seed, and the growth is not good and the susceptible plants are removed, it may also be possible to increase the seed yield and improve the varieties.

To sum up, for self-bred wheat seeds, it is not impossible to keep seeds, but it is only because there is a possibility of reducing production, so when leaving the factory, the seed bags will carry the label of no remaining seeds, in order to avoid unexpected losses to farmers. Today, many places withdraw from the seed subsidy, and they do not have to pay for the seeds themselves, and the quality of the seeds produced by professional seed companies is also relatively more guaranteed.

Here is science to promote agriculture, welcome to add attention, with you to grow knowledge.
