Summary
The concept of co-heritability is proposed in order to describe the genetic associations within pairs of quantitative traits. The mathematical relations between co-heritability, correlated response, and the coefficient of genetic prediction are shown. From observations in a diallel experiment with 10 year-old slash pine it appeared that the genetic association of a character pair is a phenomenon of low genetic variability and high inheritance. Exploratory indicators are proposed to estimate the nature of the genetic association.
