The performance of the progeny is a function of the genetic factors inherited from the parents. (Assume that “parent” means either a random plant or line from a population.) Thus, X, the parent value,...The performance of the progeny is a function of the genetic factors inherited from the parents. (Assume that “parent” means either a random plant or line from a population.) Thus, X, the parent value, is the independent variable, and Y, the progeny value, is the response or dependent variable.
The performance of a hybrid relative to its parents can be described in two ways: mid-parent heterosis is the performance of a hybrid compared with the average of the performance of its parents; high-...The performance of a hybrid relative to its parents can be described in two ways: mid-parent heterosis is the performance of a hybrid compared with the average of the performance of its parents; high-parent heterosis is a comparison of the performance of the hybrid with that of the best parent:
