Can rice keep its own seeds?

Yes, rice can be planted after planting, but the yield is very low.

In the past many years, people planted rice by keeping their own seeds and planting them the next year. Rice will certainly grow like this. Every year after rice harvest in rural areas, rice seeds that fall from rice fields will germinate, and some even grow millet. In other words, rice can leave its own seeds, but even if people leave the rice with the highest yield every year, it may not be harvested every other year.

Why don't we keep our own rice seeds now? Because their seed yield will be lower.

The seeds we bought in the seed market are all hybrid rice from Yuan Longping, so the yield will be much higher than what we keep. I believe everyone will be familiar with the word personality segregation. The existence of trait segregation means that even if hybrid rice seeds are left, high-yield rice may not be planted.

The seeds left by oneself are often eliminated because of low yield. Seeds bought from seed companies are generally cheaper and relatively secure, so it is better to buy rice seeds.
