Detailed introduction to the rice variety Guyou No. 14
After the "father of hybrid rice" Yuan Longping bred hybrid rice in the 1970s, the world experienced a second Green Revolution. However, hybrid rice seed production procedures are complicated and expensive, and there are many fake seeds on the market. How to breed apomictic rice that can be used as seed generation after generation became the long-cherished wish of many breeders. Now, apomictic rice bred by researcher Chen Jiansan, a famous breeder at the Chinese Academy of Agricultural Sciences, and other experts has realized this wish. The biggest features of apomictic rice: besides not needing annual seed production, it has also made great breakthroughs in rice quality, yield and resistance
