Characterization studies of a sheep breed are generally required to provide an overview of the breed's characteristics. Sheep that are genetically related sometimes have almost the same phenotype, making it difficult to distinguish. This study aims to determine the phenotypic diversity and use it to distinguish three genetically related sheep breeds based on the diversity of their qualitative characteristics. Sumatra Composite sheep (SC), Barbados Black belly cross (BC), and Sumatra Local sheep (SL) that were genetically related, were used in this study. Data collected were from as many as 246 adult sheep (> 1 year old) consisting of 53 heads of BC sheep, 95 heads of SC sheep, and 98 heads of SL sheep. Five qualitative traits were observed, namely the presence of horns, dominant coat color, coat color pattern, stripe color and stripe distribution. The application of SAS was used for Multiple Correspondence Analysis (MCA) to obtain traits associated with a particular sheep breed and can distinguish it from other breeds. The results showed that qualitative characteristics could be used to distinguish genetically related sheep breeds. SL ram related to brown dominant coat color, SC ram associated with white dominant coat color, while BC ram was related to white color striped, stripe distribution >20-30%, and a stripe of two colors mix as well as other characteristics. SL ewe was associated with brown dominant coat color single color pattern. In contrast, BC ewe was related to dark brown dominant coat color, black color stripes with a percentage of >10-20%, and some other color characteristics. Meanwhile, SC ewe was closely related to brown and brown-black striped, stripe distribution 1-10% and >40-50%, stripe color pattern of mix 3 colors and some other color characteristics.
