The results showed that the total dissoluble proteins hands of 8% and 10% gel were 91 and 97, respectively, and the seed salt soluble proteins bands of 10% gel were 69; All of the five alfalfa species have their own characteristic bands, which are different in number, distribution, width, and concentration; Among three methods, the five species' seed dissoluble protein fingerprints of 10% gel' bands is relatively more, which genetic diversity scattered in A, B and C regions, and can be repeated in different experiments. So it's the best fingerprint. The fingerprints of the seed dissoluble proteins and seed salt soluble proteins of five species are unanimous, which showed that: the hybrid has the nearest genetic distance with Medico go sativa cv.
