Megjegyzések:	Pigeon breeding has an extremely long history in many countries worldwide, which partly due to the high biological value of pigeon meat. At the end of the 20th century, the Hungarian squab pigeon breeders was one of the largest exporters in the world. However, this sector has collapsed in Hungary in the recent decades. Nevertheless, a number of indigenous squab pigeon breeds have survived, the suitability of which in commercial production is now questionable. The recently launched National Pigeon Program has a positive impact on the development and growth intensity of this sector. However, this requires new, modern genetic background, which are currently provided by French hybrids. In order to remain competitive and reduce imports, it is important to further develop these genotypes as well. Molecular genetic methods and precision breeding can be one of the effective tools for this. Gene polymorphism studies can be used to identify important genes or polymorphisms in individuals with specially designed primers, thus enabling faster genetic progression during the selection programs. In this work, we determined polymorphism of some muscles-related gene polymorphism in an indigenous breed (Blue Sovater) and a hybrid genotype (Mirthys). Total of 40 blood samples (20 Blue Sovater pigeons; 20 Mirthys hybrid) were genotyped using KASP-PCR method for the following genes: AGLOB, CKM, DRD4, LDHA and LDHB. The action of ?-A globin and the D4 dopamine receptor physiologically influences regulatory processes, creatine kinase is involved in the regulation of muscle function and lactate dehydrogenase genes are involved in muscle glycogenesis. The five genes in the study affect muscle function, leading to the development of appropriate meat forms. Based on the results, Blue Sovater had more polymorphic loci (4) were higher than the Mirthys hybrid (2). Because hybrids are developed to meet modern processing and consumer requirements (e.g., uniform size and meat forms), these lines have a much cleaner, more uniform genetic stock. This is beneficial for the products and production efficiency, but the reduced genetic diversity limits the possibilities for further selection. Based on our results, the Blue Sovater is characterized by greater genetic variance, which may even make it suitable as a crossing partner for the further development of hybrid lines. It also provides an opportunity to exploit and utilize the genetic resources of indigenous breeds.
