摘要

DNA polymorphism of four indigenous chicken ecotypes was assessed in Jordan using Random Amplified Polymorphic DNA (RAPD) markers. Ten RAPD markers showed high genetic polymorphism values in the 4 ecotypes located in the Northern, Eastern, Western and Southern provinces of Jordan. The effective number of alleles per locus ranged from 1.47 to 1.7 (mean 1.65). The expected heterozygosity varied from 0.28 to 0.41 (mean 0.39) and Shannon?s index from 0.42 to 0.60 (mean 0.58). The Western ecotype showed higher levels of effective allele number, expected heterozygosity and Shannon?s index than the others. The genetic similarity between the Northern, Eastern and Western ecotypes ranged from 0.95 to 0.97, while it ranged from 0.69 to 0.85 between the Southern ecotype and the others. The largest genetic distance was found between the Northern and Southern ecotypes (0.37), whereas the smallest (0.04) was between the Northern and Eastern ecotypes. The Southern ecotype was found to be the most genetically distant among all ecotypes. Based on the results, the RAPD markers were effective in detecting genetic diversity in the chicken ecotypes, representing valuable results for genetic conservation purposes.
