Comparative karyological studies on Chinese carps (Ctenopharyngodon idella, Aristichthys nobilis, Hypophthalmichthys molitrix) were carried out to determine the possiblities of hybridization. The diploid chromosome number, the morphological distribution of chromosomes, the arm ratio, the total and relative lengths of chromosomes, the total length of chromosome sets, and the number of arms were determined. Cross-breeding of grass carp and bighead was tested, and resulted in viable progeny. Karyological analyses of the F1 hybrid generation were made. The hybrid proved to be triploid.
