The missing of observations in agricultural field experiments is quite common due to several natural hazards and at present no method of analysis of diallel crosses exists when one or two observations are missing. Therefore, the method of combining ability analysis of diallel crosses (including parents and reciprocals) for one and two missing observations based on TOPHAM (1956) model and using BARTLETT (1937) missing plot technique has been presented in this paper. The formulae for estimating genetical parameters, calculatings um of squares due to these parameters and for calculating variances due to the estimates of parameters have been presented. A numerical example have been given for illustrating the technique.
