The research achievements in hybrid rice of scientist Yuan Longping, internationally regarded as the "father of hybrid rice," rewrote the history of rice cultivation in China in the second half of the 20th century. In 2003, Yuan Longping made a breakthrough in bilinear hybrid rice research. In two small demonstration fields, the per-hectare yield of super-class hybrid rice reached 12,112 kg and 12,261 kg and now large scale trials of this super-class hybrid rice are being conducted. Yuan Longping's next goal is to produce super-class hybrid rice with a yield in excess of 13,500 kg per ha before 2008.
Government programs play a significant role in improving sci-tech knowledge by conveying advanced sci-tech achievements to the countryside and to every rural household; examples include the Spark Program, the Promotion of Important Achievements Plan, the Bumper Harvest Plan, and the Prairie Fire Program.
