¹VOL, CONC, and NSP were analyzed with a trivariate approach, and the remainder of the traits were modeled with a bivariate model. If a bivariate model was used, the range of the estimates is reported. Heritability $(h^2)$and repeatability $(r^2)$estimates and standard errors are also reported.

²“—" only one estimate reported due to convergence issues.

^aReported results are the average heritabilities from the bivariate analyses with PTMot and 3HRPTMot.

^bReported results are the heritabilities from the bivariate analyses with IMot. The bivariate model with 3HRPTMot did not converge.

^cReported results are the heritabilities from the bivariate analyses with IMot. The bivariate model with PTMot did not converge.

^dReported results are the average heritabilities from the bivariate analyses with PRIM and SEC.

^eReported results are the average heritabilities from the bivariate analyses with %NORM and SEC.

^fReported results are the average heritabilities from the bivariate analyses with %NORM and PRIM.

^gReported results are the average repeatabilities from the bivariate analyses with PTMot and 3HRPTMot.

^hReported result is the repeatabilities from the bivariate analyses with IMot. The bivariate model with 3HRPTMot did not converge.

ⁱReported results are the average repeatabilities from the bivariate analyses with IMot. The bivariate model with PTMot did not converge.

^jReported results are the average repeatabilities from the bivariate analyses with PRIM and SEC.

^kReported results are the average repeatabilities from the bivariate analyses with %NORM and SEC.

^lReported results are the average repeatabilities from the bivariate analyses with %NORM and PRIM.
