Two experiments were conducted to assess the genetics of heat stress survival time (HSST) and its relationship to body weight (BW) in Japanese quail. In Experiment 1, Japanese quail from the Athens Randombred population were used and estimations of heritability (h2) and genotypic correlation (rg) were based on half-sib relationships. Three lines of Japanese quail selected under different environments and the Athens Randombred line were studied in Experiment 2. Estimations of h2 and rg were based on full-sib relationships. Heritability for HSST was moderate (.28 to .53) in Experiment 1 and low in Experiment 2 (.13 to .24). Phenotypic correlations between HSST and BW ranged from -.33 to -.05, and a negative genotypic correlations between HSST and BW suggested that selection for longer HSST would result in reduced BW.
进行了两项实验，以评估日本鹌鹑热应激存活时间（HSST）的遗传特性及其与体重（BW）的关系。在实验1中，使用了来自雅典随机繁殖种群的日本鹌鹑，并基于半同胞关系估计遗传力（h2）和基因型相关性（rg）。在实验2中，研究了在不同环境下选择的三个日本鹌鹑品系以及雅典随机繁殖品系。h2和rg的估计基于全同胞关系。热应激存活时间的遗传力在实验1中为中等（0.28至0.53），在实验2中为低（0.13至0.24）。热应激存活时间与体重之间的表型相关性在-0.33至-0.05之间，热应激存活时间与体重之间的负基因型相关性表明，选择更长的热应激存活时间将导致体重降低。
