The standardized coefficients for directional (β′) and quadratic (γ′) selection for the two consecutive years are presented.

The standard errors for coefficients estimated with the jackknife method are shown in parentheses (see text).

Bold type indicates the significant coefficients according to the sequential Bonferroni correction (Rice, 1988)
