Br Poult Sci. 1977 Jan;18(1):107-14. doi: 10.1080/00071667708416335.

Two control populations of quail of different origin were maintained by cyclical mating, one for 4 and the other for 6 generations. Means, heritabilities, genetic and phenotypic correlations of body weights at 1, 14 and 35 d and rates of gain from 1 to 14 d and from 14 to 35 d did not show any trend of change with generation. 2. The variability between generations was greater in the characters having intermediate and lower values of heritability, genetic and phenotypic correlations than in those with higher values.

通过循环交配维持了两个不同来源的鹌鹑对照群体，一个群体繁殖了4代，另一个群体繁殖了6代。1日龄、14日龄和35日龄体重以及1至14日龄和14至35日龄增重的均值、遗传力、遗传相关性和表型相关性均未显示出随代次变化的趋势。2. 与具有较高遗传力、遗传相关性和表型相关性值的性状相比，具有中等和较低遗传力、遗传相关性和表型相关性值的性状在代次间的变异性更大。
