DIALLEL Meaning and
Definition
-
Diallel refers to a specific breeding design or mating method in genetics, which involves crossing several different individuals or genetic lines with each other. The term "diallel" originates from the Greek words "di-" meaning two and "allelos" meaning different, thus indicating the occurrence of multiple crosses.
In diallel breeding, each individual or genetic line within a population is crossbred with every other individual or line within the same population. This results in a series of reciprocal crosses, conducted in all possible combinations. The main purpose of diallel mating is to specifically evaluate the general combining ability (GCA) and specific combining ability (SCA) of different genotypes.
General combining ability refers to the average performance of an individual parent when crossed with different lines, while specific combining ability refers to the interaction between specific parental combinations. Diallel analysis helps to assess the potential of different individuals or lines to contribute desirable traits to the offspring.
The diallel design is commonly used in plant breeding and animal breeding programs to enhance genetic diversity, predict inheritance patterns, estimate genetic parameters, and determine the best breeding strategy for improving populations. This method provides valuable information about the genetic basis of trait expression and enables selection for desirable traits by evaluating various combinations of parental lines.

Etymology of DIALLEL
The word "diallel" is derived from the combination of two Greek terms: "dia" meaning "through" or "across", and "allelon" meaning "one another" or "each other". Therefore, "diallel" as a whole can be understood as "across each other".
