Abstract :

Genes MYOD1 and MYF5 of the MyoD family were considered as candidate genes for growth rate and carcass traits in pigs. Products of both genes are transcription factors with domain bHLH. A relation was estimated between new polymorphisms identified in the coding and 5’ flanking regions of both genes and productive traits of 216 gilts of synthetic Line 990. Statistical evaluation was performed with the model including the fixed effect of RYR1 genotype and effect of the sire. For both genes a significant relation was identified between the novel polymorphisms and several productive traits. For some traits, heterozygotes showed the highest, while for some other the smallest values. The results suggest that novel mutations in MYOD1 and MYF5 genes could be more useful in pig selection than are mutations in the non-coding regions of both genes.
