The POLLED genotype of each polled bull based on progeny testing was available from the respective breeding organizations.
In dairy cattle, construction of a reference population started with genotyping progeny tested bulls, merely because accurate EBV based on progeny testing were available for these bulls [ 3].
In Norway, fertility has been emphasised in the total merit index from the 1970's based on progeny testing utilising large daughter groups of the NRF breed [ 18].
For example, in an experiment based on progeny from half-sib families of maize, the traits tassel branch number (NB) and grain yield (GY) were evaluated and found to be highly and negatively correlated (rG = -0.719).
The accuracy of GBV was assessed in a group of purebred industry sires based on the correlation coefficient between GBV and accurate estimated breeding values based on progeny records.
The EBVs are predictions of the sire's relative genetic merit for the EMD trait based on progeny performance data collected from large numbers of animals over two seasons (2003/2004 and 2004/2005).

The second pedigree, SNP PED 421, was based on progeny-tested animals that could be traced back to ancestor A0, and consisted of 175 genotyped and phenotyped sons, eight genotyped and 238 non genotyped ancestors.
Genomic evaluation was performed based on genomic best linear unbiased prediction and its accuracy was evaluated as the Pearson correlation coefficient between genomic estimated breeding values using either observed (12k/50k) or imputed genotypes with varying levels of imputation accuracy and accurate estimated breeding values based on progeny-tests.
For example, with 4 000 phenotypic records and 20 progeny per sire, the reference population consists of n P = 200 genotyped sires with EBV based on 20 progeny, whereas with two progeny per sire, the reference population consists of n P = 2 000 genotyped sires with EBV based on two progeny.
We assumed the different trend existing in our study was related to the drop in accuracy observed for non-progeny-tested individuals, which occurred because the calibration of the GS model was based on the progeny tests of only 120 individuals per population.
Insectary experiments based on the progeny of field-caught Cx. pipiens females revealed strong associations between alternative traits that define molestus and pipiens forms.
