【 摘 要 】

Genotype and allele frequencies of the oestrogen receptor gene (ESR) PvuII restriction site were investigated in populations of the main Czech maternal breeds. 1253 sows and gilts and 396 boars in Large White and 334 sows and gilts and 318 boars in Landrace were genotyped from blood samples by the modified PCR-RFLP procedure as described in Short et al. (1997). In Large White, the frequency of allele B was about 0.51. In Landrace, the frequency of allele B reached from 0.02 for boars to 0.03 for sows. No significant deviations of the observed genotype frequencies from the frequencies expected according to Hardy-Weinberg equilibrium were found in both breed. Opposite trends in allele frequencies development could be assumed for analysed sows and boars of both breeds. In Large White sows the frequency of allele B raised probably due prefering sows with BB genotype, whereas in Landrace population the frequency of allele B decreased from yet unknown reasons.
