Near infrared spectroscopy(NIR) has been used widely in many research areas because of its unique technical advantages. In this paper, the NIR technique's concept and its application situation in non-destructive testing were briefly illustrated, and the method for determination of the hard seed percentage with NIR were introduced in detail on the basis of reviewing the application of NIR on qualitative identification of the hard seed percentage. Also，the existing problems and research direction were issued. The aim of this paper was to provide assistance in researching on the non-destructive testing method for hard seed percentage. It will be meaningful to help the future researches on the traits of hard seeds.
