Abstract
Non additive genetic component that is the base of a quantitative character has no predictability, this is the reason for which the present paper is proposing to appreciate the special combinatory capacity for nests average weight and average body mass of the rabbits at the age of 14 days, in a specific crossing scheme combining three rabbit breeds common in Timis county breeders New Zealand White, Large Chinchilla and Californian. The data obtained, statistically analyzed, proves a good special combinative capacity for this characters, for which reason this crossing scheme is recommended for producing meat individuals destined for slaughterhouses. This scheme provides an exploitation of the high fervency of the heterozygote at maternal forms and at the final hybrids.

Key words: special combinative capacity, crossing, hybrids
