On this article a method is proposed for the estimation of the values of missing crosses in the case of a diallel analysis of the type p (p-l)/2. The method of estimation is based on the minimization of the sum of squares of the specific combining ability, the derivation of the formula of estimation has been done for the case of one missing cross, but its extension for the case of more than one missing cross is also suggested. Estimated values can be used to predict the double cross perfomance on a corn breeding program.
