Throughout the present study the effect of using markers close to genes affecting a trait, as
compared with the use of all the markers of a genome, and also the effect of on increase in the
number of reference groups, on the accuracy of a genetic evaluation, was investigated. Genomic
evaluation was done using BLUP method. The results indicated that use of markers close to genes
affecting a trait and on increase in the number of reference groups would enhance the accuracy in
an evaluation of the Estimated Breeding Values (EBVs). Use of phenotypic records (in
comparison with breeding values of reference group) would result in an increase in the accuracy of
estimating the breeding values by use of markers close to the effective genes on the trait as
compared with the use of all the markers of a genome. Increase in number of generations between
reference and validation groups would result in a decrease of the accuracy of EBVs.
