Abstract
In this study the genetic resource of Pelung chicken from Cianjur, West Java, Indonesia, was exploited. Pelung chicken has a higher body weight growth, unique meat flavor, and superior posture, compared with other indigenous breeds. Kamper chicken line selective breeding program was conducted, to increase the performance of Pelung breed by crossing with Layer Lohmann Brown-Classic. The Layer Lohmann Brown-Classic is an imported laying-type breed, which is widely known for its reproductive performance, based on the egg productivity. This study aims to use quantitative genetic method in estimating the commercial and reproductive traits' performance of Kamper chicken line. Based on commercial, phenotypic and reproductive traits, the progenies in Kamper chicken line have significant improvements, compared to the parental cross of Pelung and Layer Lohmann Brown-Classic. The quantitative genetic method was used in describing and underlying some phenomenon, in the selective breeding program. Although quantitative genetic method is utilized in basic breeding program with significant precision and rapidness, it is only used in the preliminary study, for the advanced type. Therefore, the addition of quantitative trait loci (QTL), provide a more thorough genetic examination, and play a role in selective breeding program.

Summary
Human population growth subsequently aligns with the increasing demand for food production. The rise in the world population and urbanization increase the demand for poultry meat and eggs, which is expected to grow at a rate of 20% in the decade (Diambra-Odi, 2014; Mottet & Tempio, 2017). To close the gap in the food sector, there is a need to empower innovation, collaboration, and research, in providing the necessary solution. Agriculture and poultry sectors have long been the backbone of Indonesia’s food main source, they are currently dependent on foreign products, such as feed, seeds, and various commercially domesticated animal breeds. While the innovation and research of natural feeding source continues to improve, in order to replace food additive, for example using herbs or in combination with probiotics, Lactobacillus spp. An approach to genetic improvement is needed, in providing a more sustainable solution
