Three biometrical techniques, viz., diallel, partial and line x tester crosses are known as mating designs. These biometrical techniques are extensively used in crop improvement programmes for evaluating inbred lines in terms of genetic components of variation and evaluate several single crosses at a time. Diallel mating design is used to evaluate several inbred lines in terms of combining ability variances and effects. Diallel cross refers to mating of selected parents in all possible combinations and evaluation of a set of diallel crosses is known as diallel analysis. Diallel is a Greek word and introduced by Schmidt in 1919. Procedures of diallel cross analysis for the study of polygenic traits in self pollinated species was developed by Jinks and Hayman in 1954.
