World famous biologist Niu Man Chiang, a Chinese American, arrived in southwest China's Guizhou Province Saturday for a seven-day visit.

Niu, founder of the theory of epigene, has successfully created a kind of genetically modified corn, which, for its' high nutrition and economic value, is believed to be the best choice for poverty-alleviation projects.

Last year, the Niu Man Chiang Foundation donated some seeds of genetically modified corn to Guizhou and the pilot cultivation there has proven to be satisfactory.

This kind of corn is sown in some 67 hectares of land in the Guangxi Zhuang Autonomous Region near Guizhou this year, and the acreage is expected to increase to 67,000 hectares there, according to sources with the foundation.

Guizhou's Deputy Governor Mo Shireng told the 89-year-old Niu at a meeting Saturday evening that the province attaches importance to the test cultivation of the genetically modified plant and will expand the growing of it.
