What are the rice varieties of Yuan Longping?

When it comes to rice, in addition to eating rice, people will also think of Yuan Longping, the father of Chinese hybrid rice. Because he successfully cultivated hybrid rice, he increased the yield of rice per mu and solved the problem of food and clothing for people. What are the rice varieties of Yuan Longping? Do you know? Let's learn about it.

1. Hybrid rice

Hybrid rice is a high-yielding hybrid rice variety cultivated by Yuan Longping. It is a hybrid rice variety bred by crossing between common rice and wild rice found in Hainan. The gene of Hainan wild rice is different from that of common rice. through hybridization and gene recombination, the offspring gain heterosis by making use of the genetic differences between artificially cultivated rice and wild rice to make Yuan Longping cultivate hybrid rice.

2. Sea rice

Sea rice is not planted in the sea, but on the beach by the sea. Because it is not afraid of short-term immersion in sea water and saline-alkali resistance, the research value is very high. Tianlongyou 619, a high salt-resistant rice variety bred by Yuan Longping's team, has the characteristics of disease and insect resistance, saline-alkali resistance, lodging resistance and yield of 300-400 kg per mu, so it is suitable for planting in saline-alkali land in most areas of our country.

3. Cadmium-free rice

Cadmium (g é) is a kind of heavy metal harmful to human body. It is not the element that our bodies need. Cadmium will be discharged into the environment through waste water, and then into the food through irrigation. Rice is a typical damaged crop, which is where "cadmium rice" comes from. If the human body eats food containing cadmium for a long time, it will get painful disease (that is, bone cancer). The cadmium-free rice cultivated by Yuan Longping "knocks out" the genes that contain cadmium or absorb cadmium in the parents. If the parents are clean, the seeds will naturally be clean.

4. Super hybrid rice

The super hybrid rice variety Xiangliangyou 900 (Chaoyouqian) cultivated by Yuan Longping, the father of hybrid rice, and his team set a record for yield per mu, with a yield of 1203.36 kg per mu in the experimental field. Xiangliangyou 900 rice has balanced growth, large panicle and many grains, high seed setting rate, no major diseases and a new world record in yield.

Yuan Longping devoted all his life to the research of hybrid rice, made outstanding contributions to China's rice development and food supply, and made China's hybrid rice technology lead the world all the time. Because of him, farmers are no longer hungry. No wonder he was welcomed by tens of thousands of young students at the opening ceremony of Hunan Agricultural University and was rated as a "real giant star chase scene" by netizens.
