"Brown" is the second plumage color mutation reported in Chinese painted quail (Excalfactoria chinensis). The brown plumage lacks the wild-type black pigmentation that is a representative component of the wild-type plumage; otherwise, the plumage pattern is the same as that of the wild type. The dorsal surface of the female is brown with gray tinge, while that of the male is dark brown with a bluish-gray tinge. The breast of the female is creamy light-brown with numerous gray speckles. The coloration of the ventral surface of the mutant male is generally similar to that of the wild type except for the chin. The mutant chin is charcoal gray with a brown tinge, differing from the dense black of the wild-type chin. The basic color of the chick down is greenish creamy-yellow with bright brown tinge. The down has the same stripe pattern as the wild type, but the color of the stripes is lighter brown. A genetic analysis indicated that the brown plumage is controlled by an autosomal recessive gene, for which the symbol br is proposed. The br gene is not allelic and not linked to the previously reported light gray (Ig) gene.
“棕色”是中国鹌鹑（中华鹌鹑）中报道的第二种羽毛颜色突变。棕色羽毛缺乏野生型黑色色素沉着，而黑色色素沉着是野生型羽毛的一个典型组成部分；除此之外，羽毛图案与野生型相同。雌性的背部呈带灰色调的棕色，而雄性的背部呈带蓝灰色调的深棕色。雌性的胸部是乳黄色浅棕色，有许多灰色斑点。除了下巴，突变雄性腹部表面的颜色通常与野生型相似。突变的下巴是带棕色色调的炭灰色，与野生型下巴的深黑色不同。雏鸟绒毛的基本颜色是带亮棕色色调的绿乳黄色。绒毛具有与野生型相同的条纹图案，但条纹的颜色是浅棕色。遗传分析表明，棕色羽毛由一个常染色体隐性基因控制，为此提出符号br。br基因与之前报道的浅灰色（Ig）基因非等位且不连锁。
