Japanese quail (Coturnix coturnix japonica) were divergently selected for 12 generations for increased (high stress, HS) and decreased (low stress, LS) blood corticosterone (B) response to unfamiliar environments. Response lines were selected initially on the basis of wild-type quail B response to albino (ALB) quail intrusion (S1 to S3) and subsequently on B response to immobilization (IMB) (S4 to S12). Using ALB intruders as stressors proved unsuccessful, therefore the practice was abandoned in favor of using IMB, which proved successful. Across nine generations of selection, using the IMB stressor, the HS line exhibited a mean serum B response that was approximately 58% greater than that of the random-bred (control stress, CS) line, whereas the LS line had a mean response approximately 23% less than that of the CS line. Selection differentials were approximately three-fold greater in the HS than in the LS line whereas realized heritabilities (h2) were approximately two-fold greater in the HS than in the LS line.
日本鹌鹑（Coturnix coturnix japonica）被分为高应激（HS）和低应激（LS）两组，进行了12代的定向选择，以提高（高应激组）和降低（低应激组）对陌生环境的血液皮质酮（B）反应。最初根据野生型鹌鹑对白化鹌鹑（ALB）入侵的B反应（S1至S3）选择反应系，随后根据对固定（IMB）的B反应（S4至S12）进行选择。事实证明，使用ALB入侵者作为应激源并不成功，因此放弃了这种做法，转而采用IMB，结果证明是成功的。在使用IMB应激源进行的九代选择中，HS系的平均血清B反应比随机繁殖（对照应激，CS）系高约58%，而LS系的平均反应比CS系低约23%。HS系的选择差约为LS系的三倍，而实际遗传力（h2）HS系约为LS系的两倍。
