Additive genetic components of variance and narrowsense heritabilities were estimated for flowering time (FT) and cutflower yield (Y) for six generations of the Davis Population of gerbera using DerivativeFree Restricted Maximum Likelihood (DFRML). Additive genetic variance accounted for 54% of the total variability for FT and 30% of the total variability for Y. The heritability of FT (0.54) agreed with previous ANOVAbased estimates. However, the heritability of Y (0.30) was substantially lower than estimates using ANOVA. The advantages of DFRML and its applications in the estimation of components of genetic variance and heritabilities of plant populations are discussed.
