Abstract: In order to make clear the hybrid F1 (Dehong buffalo譔ili-Ravi buffalo) bulls karyotype and fertility and the relationship between them and the parents, the study cultrued lymphocyte in the hybrid F1 (Dehong buffalo, Nili-Ravi buffalo, Nili-Ravi譊ehong buffalo)males by peripheral blood lymphocyte culturing, made chromosomal sample and G-band dyeing. Then chromosome karyotypes in them were analysed and made sure by BEION Karyotyping system. The results showed that the karyotype of Dehong buffalo was 2n=50, XY, Nili-Ravi buffalo was 48,-4,-4,-9,-9,+t(4;9),+t(4;9),XY and hybrid F1(Nili-Ravi譊ehong buffalo) 49,-4,-9,+t(4;9),XY.
