Abstract: PCR-SSCP was used in this study to detect H-FABP 5’UTR polymorphisms in 16 Red Steppe hybrids crossed with Limousin. The correlationship was carried out between different genotype and meat quality.The results showed that 5’UTR of H-FABP gene exist polymorphisms in Red Steppe Crossed Herds, base T was inserted in 136 bp and the transformation of G→A in 142 bp. A genotype was negatively to the tenderness trait. The difference between AA with AB and BB was extremely significant (P<0.01) in tenderness, but AB and BB was no significant difference(P>0.05).The difference between genotype with the other meat quality was not significant (P>0.05). The effect was very significant of H-FABP gene to tenderness traits in Red Steppe Crossed Herds.
