What Do You Mean by Diallel Crosses?

Definition. The term diallel implies all probable crosses among a collection of set of animals. According to Hayman, a diallel cross can be defined as the set of all possible crosses between several genotypes, which may be individuals, clones, homozygous lines, etc.

How is diallel cross calculated?

This includes one way crosses and parents. The total number of entries to be evaluated is equal to P(P+1)/2, where P = number of parents. This can be used when parents do not have self incompatibility or male sterility. The inclusion of parents in the experiment permits the estimates of heterosis.

Why partial diallel cross is important?

Kempthorne and Curnow (1961) suggested the partial diallel cross to allow the evaluation of a greater number of inbred lines in crosses. According to this procedure, each of the n lines in the set are crossed with s other lines of the same set, instead of (n - 1) lines as in the complete diallel.
