, 2008 ). Many of these wild and weedy relatives have undesirable characteristics such as high or low flesh pH or low sugar content. Estimates of heritability and correlations among traits can help in the selection of breeding strategies and selection of

Fraser fir established in 1983 found significant differences among sources and among families within seed sources for all traits measured ( Arnold and Jett, 1995 ; Arnold et al., 1994b ; Jett et al., 1993 ). Heritabilities for most traits important in
