A joint research project being undertaken by Chinese scientists from Hong Kong, the US and China is expected to result in a genetically modified 'super rice' that could yield double the harvest of normal grain by 2008, reports the South China Morning Post . Traditionally, the yield of rice is about 360kg per mu, a Chinese land measurement equivalent to about 0.6 hectares. First-generation hybrid rice, which is already feeding half the population of China, provides about 450kg per mu, a figure that could be doubled to 900kg if the new technology is developed as foreseen.
