PCR-RFLP technique was applied to analyze the polymorphisms of GHR intron 5 and IGF-1 of Wenchang chickens. The effects of GHR intron 5 and IGF-1 on the egg quality were analyzed. The results showed that the allele frequencies of C, D were 0.19, 0.81 for GHR-Intron 5 and the allele frequencies of A, B were 0.53, 0.47 for IGF-1, respectively. Three significant were observed for GHR and EST; for IGF-1 and ESW and for IGF-1 and ESS.} }
