%X Golden Kamper is a local meat-typed chicken with four generations of Pelung male and Layer female selective breeding. This chicken has various plumage colors and patterns. Therefore, the desired plumage color is red barred plumage (B1). In chickens, the missense mutation in the Tyrosinase-related-proteins 1 (TYRP1) causes a chocolate color plumage (choc) with an epistatic effect on barred plumage. The current study aimed to observe the growth of 16 chickens from hatching until 49 days of age to investigate the phenotypic characteristics, especially plumage color at 49-day-old chickens, then to determine the effect of the TYRP1 polymorphism on F4 Golden Kamper phenotypes. The methods used in this study included selective breeding among F3 Golden Kamper, collection of F3 Golden Kamper’s eggs, then rearing the day-old chickens of F4 Golden Kamper. Phenotypic data were collected and blood collection was performed for DNA isolation, DNA amplification, and sequencing. Of 16 F4 Golden Kamper, all chickens had a uniform comb type of single (rprp, 100). The produced shank colors were white (31.25), yellow (62.5), and blackish gray (6.25). The plumage colors were red barred (12.5), white barred (12.5), brown (68.75), and chocolate (6.25). The bodyweight of F4 Golden Kamper at the age of 7 weeks reached 597.3 g. The morphometric results indicated that F4 Golden Kamper had the same posture and body proportions as Pelung chickens, however, with a higher weight. Fourteen substitutions were found in the TYRP1 fragment of F4 Golden Kamper. The single nucleotide polymorphisms (SNP) had no correlation with the chocolate plumage phenotype in F4 Golden Kamper. The evaluated SNPs in TYRP1 were not associated with the brown plumage color phenotype. © 2022
