Q Your hybrid corn growing areas expand very fast. When do you expect China will grow
hybrid corn on 1~ of the area?
A It's very difficult to achieve 1~ because there are still some highland, or areas with
very poor soi ls for growing maize which are not convenient for hybrids.
FROM: G. Granados
Q one of the main factors for yield reduction in SOUth China is drought. Have you identified
sources of resistance to drought, and if so, how are you using them?
A We have identified sources of resistance to drought from local varieties by China
National Maize Program. Now we are developing inbred lines from those sources.
