Abstract

The invention discloses a hybridization breeding method of a novel variety black goat, which comprises enabling a black goat to serve as a female parent to respectively hybridize with a Nanjiang yellow goat and a Nubian ibex, respectively obtaining an F1-generation Nanjiang black hybrid and an F1-generation Nubian black hybrid, obtaining an F2-generation Nanjiang black hybrid and an F2-generationNubian black hybrid by backcrossing with the black goat, hybridizing the F2-generation Nanjiang black hybrid with the F2-generation Nubian black hybrid to obtain an F3-generation hybrid goat, and performing crossing fixed breeding of the F3-generation hybrid goat to obtain the novel variety black goat. The method enables a pure-breed black goat to respectively hybridize with the Nanjiang yellow goat and the Nubian ibex, overcomes the shortcoming of a single-hybridization black goat variety, and has the advantages of obtaining good meat quality and flavor, high adaptability, high growing speedand the like.
