At present, as much as 50 percent of China's total number of rice paddies grow Yuan Longping's hybrid rice species and these hybrid rice paddies yield 60 percent of the total rice production in China. Due to Yuan's hard work, China's total rice output rose from 56.9 million tons in 1950 to 194.7 million tons in 2017; about 300 billion kilograms of rice has been produced over the last twenty years, compared to the estimated amount that would have been produced without the hybrid rice species. The annual yield increase is enough to feed 60 million additional people.
