Abstract:

A diallel cross is a mating scheme which has been utilized for investigating the genetic underpinnings of traits with quantitative nature. In field of animal and poultry breeding, it has vast scope for improving the production performances. To exploit the full advantage of diallel crossing with ease, the different modifications viz. full, partial, incomplete and complete diallel crossing had been developed. The genetic basis for improvement in performance due to diallel cross is attributed to two main factors i.e. direct genetic effects (due to additive gene action) and various dominance genetic effects (due to non-additive gene action). Hence, the utilization of various effects i.e. direct genetic effects, reciprocal effects, utilization of effects due to general/specific combining ability, maternal and heterotic effects should be performed. However, the rate of genetic improvement varies with the different species of livestock i.e. higher rate on animals which are prolific/shorter generation interval while lower rate with animals of shorter generation interval. Thus, this tool of genetic improvement should be judiciously used considering the socio-economic and cultural values of livestock in different societies or regions.
