In 1963, when Cheng Xiangwen was assigned to work as a seed cultivation technician at a farm in Henan province's Xunxian county, corn production in the area was just above 750 kilograms per hectare.
Even though the farmers worked hard, they could not harvest enough corn, a food staple, to feed their families due to low yields. The situation hit home with Cheng, who had just graduated from vocational school.
"After that, I made up my mind to cultivate new corn varieties so the land would produce more grain," said 84-year-old Cheng, chief expert in corn cultivation at the Hebi Academy of Agricultural Sciences in Henan.
