• Genomic selection in Canadian spruces 

      El-Kassaby, Yousry A.; Ratcliffe, Blaise; El-Dien, Omnia Gamal; Shuzhen, Sun; Chen, Charles; Cappa, Eduardo Pablo; Porth, Ilga M. (Springer, 2020-01-01)
      The genetic gain of spruce (Picea spp.) breeding programs is impeded by long recurrent selection cycles stemming from biological constraints such as late expression of traits, weak juvenile mature correlations, and late ...
    • Single-step BLUP with varying genotyping effort in open-pollinated Picea glauca 

      Ratcliffe, Blaise; El-Dien, Omnia Gamal; Cappa, Eduardo Pablo; Porth, Ilga; Klapste, Jaroslav; El-Kassaby, Yousry A.; Chen, Charles (2017-03)
      Maximization of genetic gain in forest tree breeding programs is contingent on the accuracy of the predicted breeding values and precision of the estimated genetic parameters. We investigated the effect of the combined use ...
