The export and overseas development of Chinese hybrid rice technology is in flourishing tendency with a potentially large market, a remarkable technological and personal advantage and a good fundamental condition, however, is still in the initial stage presently. Seed quarantine barrier, insufficient early input, self-deficiency of hybrid rice, disorder management and export restrictions are the main difficulties and restricting factors in the export of hybrid rice technology. To accelerate the overseas development of Chinese hybrid rice technology, countermeasures should be adopted, such as optimizing strategies, regularizing export, breaking the export barrier, improving seed quality and policy supporting., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null,
