Conteúdo: | The canchim is a synthetic beff caattle breed, produced by crosse betwen charolais (Bos taurus) and bos indicus breeds (Zebu). With a genetic composition of 5/8 Charolais + 3/8 zebu, Canchim combines growth ability associated with a bos taurus breed and tolerance to tropical environments that attributed to Zebu breeds. The herd used in this study was formed in 1953 and subjectd to phenotypicc selection for yealing weiht and fertility, under pasture management. Even though the average inbreeding coefficient was kept low by avoiding consaguineous mating (Alencar et al., 1981), genetic variability losses could be ecpected as a result of selection and restricted effective mumber (Ne), since there was no introction of ouside animals. The objective of this study wasto evaluate genetic variability parameters estimated from molecular dara.
