TropCRD (Tropical Crop Resources Database): the multi-tropical crop variation information system

TropCRD (www.tropical-resources.org.cn) is organized on a crop basis with current Manihot esculenta Crantz, Hevea brasiliensis, Saccharum officinarum L., Ananas comosus, Mangifera indica L. and other tropical crop species. TropCRD is currently divided into four modules: genome module, variation module, molecular marker module and tools module. These data and tools are available for further research by geneticists and tropical crop breeders, including the application of marker-assisted selection techniques and genomic selective breeding to tropical crop breeding. It provides important support for tropical crop breeding research, and also provides valuable resources for obtaining and analyzing the genome sequence data, genetic variation and functional annotation of tropical crops.
