The invention belongs to the technical field of hybrid seed production, and discloses an information collection and measurement system used in hybrid seed production of carp and a measurement method.The information collection and measurement system used in hybrid seed production of the carp comprises a species numbering module, an information registration module, a central processing module, a purity identification module, a matching hybridization module, an accounting module, a data storage module and a display module. Through the purity identification module, the purity of hybrid seeds canbe quickly identified, the identification time is short, the cost is low, it is not required that a testing person has specialized knowledge, and the system is convenient to use. Through the species numbering module, the information registration module, the matching hybridization module and the accounting module, a perfect management mechanism is provided, so that a method and processes of the hybrid seed production of the carp are easily standardized, the hybrid seed production efficiency is improved, and a parent and a good variety which are rich in hereditary basis and good in combining ability and gather more favorable genes are easily bred.
