家鸡的羽毛的结构色具有观赏价值与经济价值.该研究旨在建立出一套系统客观的家鸡羽毛结构色定量检测方法,对 735 只荆门黑羽绿壳蛋鸡母鸡的羽毛结构色进行图片采集方法和定量指标的探究,同时利用单元内混合家系相关法进行遗传力的估计.结果显示,Lab色彩模型中的a值与b值可以作为对结构色进行定量的光学指标;相对于鞍羽、肩羽来说,翼羽中的次级大覆羽结构色光学指标与鸡只整体的结构色关联更强;次级大覆羽的a值为中等遗传力,b值为高遗传力且其个体内测定变异程度较小.可见,次级大覆羽的b值可能更适合作为遗传育种的选育指标,能够对家鸡羽毛结构色进行定量,并用于育种实践中实现对结构色的特色化选育.
Study on Quantitative Detection Method of Structural Color of Domestic Chicken Feathers
The structural color of domestic chicken feathers is a trait with ornamental and economic values.The aim of this study is to propose a systematic,objective,and quantitative detection methods for structural color of domestic chicken feathers.We studied 753 females of Jingmen Black Plumage Blue-shell layer for establishing the picture acquirement method and selecting the quantita-tive parameters.The heritability was estimated by the mixed family correlation method within families.The results show that the"a"value and"b"value in the Lab color space can be used to quantify the structure color.Compared with the saddle and shoulder feathers,the optical parameters of the secondary wing bar are the most relevant to the general degree of whole-body structural color.The"a"value of the secondary wing bar has a medium heritability,the"b"value has a high heritability and the degree of variation is smaller.It can be seen that the"b"value of the secondary wing bar may be more suitable as a selection target for breeding im-provement.It can quantify the structural color of chicken feathers,and can be used in breeding practice to achieve characteristic breeding of structural color.
