Revising the use of age-age correlation for conifer tree breeding in Alberta

Description

This paper describes an attempt to develop correlation prediction equations using data from Alberta species grown in the Alberta environment. It changes the form of the equation used by Lambeth by inputting the age difference between measurement and rotation ages as a predictor variable as opposed to an age ratio that Lambeth uses, which inadvertently equates the latest field measurement to a rotation age measurement. it should be noted that this paper is not intended to increase the size of the age-age correlation compared to what could be obtained by Lambeth. it is only intended to provide an empirical procedure of obtaining a correlation that is biologically meaningful and partly related to the species and trials for which the genetic gain is being sought.
