Crop genetic germplasm is the most important basis for crop genetic improvement. The levels of research on crop germplasm indicated the core competing ability of crop breeding. In this paper, we searched the SCIE data base and analyzed the publications in field of crop germplasms identification and utilization, the results show that China ranks in number one in all the countries in number of publications and genetic diversity is still the main objective but the characteristics and methods used extended to new generation of molecular markers such as SNP. The Wild crop germplasms were much more concerned than before. The current status of study on crop genetic germplasm in China was reviewed and precision phenotyping of crop germplasm was suggested.
