摘　　要：性连锁矮小基因(dw基因)在蛋鸡、肉种鸡生产中应用较为广泛。随着矮小基因分子诊断技术日益成熟以及矮小鸡生理特性研究广泛开展,矮小基因在地方鸡遗传改良中有着美好的应用前景。基因组结构对矮小基因的影响较大,但很少有以国内地方鸡品种为遗传背景研究矮小基因及矮小鸡的生理特性。本文综述了矮小鸡生理特性研究成果,总结讨论了矮小基因在养鸡生产中的应用。Sex-linked dwarf gene was applied extensively in layer and broiler breeder. Advance with the diagnostic methods on dw gene and physiological characteristics on the dwarf fowls, it appears promising for applying dw gene in the local chicken improvement. Effects of dw gene vary with genetic structures, but few research of dw gene were based on Chinese local chickens. In this paper, studies of the dwarf fowls were re- viewed and the application of dw gene in poultry industry discussed.
