Using usual method, we got karyotype of hybrid pig (wild soar (male symbol) x domestic pig (female symbol)), C-band and approximate 174 bands of G-band, and we also obtained approximate 258 bands of high resolution G-band by micro-Colchicin method. The result indicate that the diploid chromosome number is 2n=38; there is polymorphism in C-band,and compared with domestic pig in G-band and high resolution G-band there is no distinguish difference. They belong to the same seed.
