   “The corn seed of the best quality” has been company motto since Lantron was established in 2001.  We have adopted the ISO9001 International quality management system and was certified independently as ISO9001 holder. Lantron is the first in the nation to promote the idea of “tri-quality” corn seed standard: with quality better than international grade 2, germination rate of 90% for quality seed , and more than 95% for extremely high quality seed.
   In the choice of production base, Lantron selects the lands most suitable for maize seed production in Northwest China Hexi Corridor region at Gansu Province to set up production bases, which has good sun-light resource, high soil fertility, dry climate, long frost-free period, and less pests and diseases (see Figure 1).
