What rice varieties did Yuan Longping develop?
When it comes to rice, besides thinking of the rice we eat, everyone also thinks of the father of Chinese hybrid rice - Yuan Longping. It was because he successfully developed hybrid rice that the per-mu yield of rice increased and people's food and clothing needs were met. As for what Yuan Longping's rice varieties are, do you know? Let's find out below.
1. Hybrid rice
Hybrid rice is a high-yield hybrid rice variety developed by Yuan Longping. It was produced by crossing ordinary rice with wild rice discovered in Hainan to obtain heterosis, thereby developing this rice variety. The genes of Hainan wild rice differ from those of ordinary rice. Through hybridization and gene recombination, the offspring obtain heterosis. By utilizing the genetic differences between artificially cultivated rice and wild rice, Yuan Longping developed hybrid rice.
2. Seawater rice
Seawater rice is not planted in seawater, but on tidal flats by the sea. Because it withstands short-term soaking in seawater and is salt-alkali tolerant, its research value is extremely high. The highly salt-resistant rice variety developed by Yuan Longping's team - Tianlongyou 619 - has characteristics such as resistance to pests and diseases, resistance to salt and alkali, resistance to lodging, and a per-mu yield of 300-400 kg. It is suitable for planting in saline-alkali land in most areas of our country.
3. Cadmium-free rice
Cadmium (gé) is a heavy metal harmful to the human body. It is not an element our bodies need. Cadmium is discharged into the environment through wastewater, then enters food through irrigation. Rice is a typical victim crop, and this is how "cadmium rice" comes about. Long-term consumption of cadmium-containing food by humans can cause itai-itai disease (i.e., bone cancer disease). The cadmium-free rice developed by Yuan Longping works by "knocking out" the cadmium-containing or cadmium-absorbing genes in the parent plants. Once the parent plants are clean, the seeds are naturally clean.
4. Super hybrid rice
The super hybrid rice variety "Xiangliangyou 900 (Chaoyou Qianhao)" developed by "the father of hybrid rice" Yuan Longping and his team set a per-mu yield record. In the experimental field, this rice variety reached a per-mu yield of 1203.36 kg. Xiangliangyou 900 rice grows evenly, has large panicles and many grains, a high seed-setting rate, and no major diseases, and its yield set a world record.
Yuan Longping devoted his life to the research of hybrid rice, made outstanding contributions to the development of rice and the food supply of our country, and also kept our country's hybrid rice technology leading the world. Because of him, farmers no longer go hungry. No wonder that at the opening ceremony of Hunan Agricultural University, he was welcomed by tens of thousands of young students lining the roads, and was rated by netizens as "a truly massive star-chasing scene."
