Abstract:Full seed model was evaluated by using, in multiple environments, mating design of eight parents diallel crosses with F1’s and reciprocal F1’s, F2’s andreciprocal F2’s. Monte Carlo simulations were conducted to calculate Bias, MSE and power value to estimate variance components of embryo genetic effect, endosperm genetic effect, cytoplasm effect, maternal genetic effect and genotype x environment interaction effect. Biases of variance components, σ 2Ao, σ 2Do and σ 2Ae, were found to be around 10% of the parameter values. These variances tend to be well estimated for the full seed model including GE interaction effect. If embryo or endosperm genetic effects, when they do exist, are not considered in the model, other genetic variance components could be easily overestimated except σ 2C, σ 2Dm, σ 2CE, σ 2DmE and σ 2ε. If embryo and embryo x environment interaction were ignored, endosperm, maternal genetic variances and genotype x environment genetic variances were overestimated. When endosperm and endosperm x environment interaction were ignored, same phenomena happened to embryo, maternal and GE interaction variances components.
