Results of interpopulation crossing test of mating, fertilization rate, embryo growth and hatchability under the condition of cage feeding indicated that:(1) due to difference in body size, morphology, habits and characteristics and reproducing season, crossing fertility between wild Japanese quail in China and domestic quail population was lower than that of intrapopulation mating, but fertilized egg through reciprocal crossing could be incubated and produced F1 without prezygotic isolation;(2) crossing of wild male quail ?female small-type domestic quail produced the best effect among all combinations of reciprocal crossings.

通过关于笼饲环境下交配行为、受精率、胚胎发育、种蛋孵化率的种群间杂交试验证明：由于体量、形态、习性、繁殖季节性的差异，我国境内的野生日本鸣鹑与家鹑群体之间的杂交能育性低于同种群交配水平，但可以实现正、反杂交，产生受精卵、孵出杂种一代，不存在合子前生殖隔离；在正反杂交组合中，以野雄鹑X小型雌家鹑的效果最好。
