“…This result showed that genetic diversity in the four indigenous chicken breeds was high. A similar result (0.45 -0.67) was reported by Wimmers et al (2000) for African, Asian and South American local chickens. However, the mean He recorded in this research is lower than that reported by Zhang et al (2002) in Chinese native chickens (0.63 -0.86) and by Shahbazi et al (2007) in Iranian native chickens (0.62 -0.74).…”

The genetic diversity of four protected indigenous chicken breeds was evaluated with 25 microsatellite markers. Polymorphism information content (PIC), heterozygosity with the estimator of genetic differentiation F ST and Nei's genetic distance were evaluated. The results showed that these four protected local chicken populations showed high levels of diversity. The proportion of inter-population subdivision among the four protected local chicken populations was 16.0%. The average heterozygosity was 0.514, 0.581, 0.567 and 0.589 in Dongan, Xuefeng black-bone, Xianghuang and Taoyuan chickens, respectively, while the average PIC estimates were 0.455, 0.581, 0.557 and 0.576. A phylogenetic tree was constructed using genetic distance and the neighbour-joining method. Its topology reflects the general pattern of genetic differentiation among the four chicken breeds. The results also showed high genetic diversity and genetic variation among all the breeds. The information about the four local breeds estimated by microsatellite analysis may be useful as an initial guide for the effective conservation of chicken genetic diversity and developing conservation strategies.

“…As a result of the FAO's recommendation and their availability through genomic mapping, microsatellites have been widely used to characterise genetic diversity. Genetic distances calculated from microsatellite data have been advocated as an objective criterion for making conservation decisions (Barker, 1999;Wimmers et al, 2000). However, other authors have severely criticised this approach and emphasised that aspects such as adaptive features and traits of economic or scientific importance are infrequently available for genetic distance measures.…”

The Iberian breed is the most important pig population of the Mediterranean type. The genetic structure of two strains (Torbiscal and Guadyerbas) and three varieties (Retinto, Entrepelado and Lampiñ o) of this breed was studied using 173 pigs genotyped for 36 microsatellites. In addition, 40 pigs of the related Duroc breed were also analysed. In the 1960s, the Iberian breed's numbers were severely reduced by disease, due to economic change and to crossbreeding. Varieties are in danger of disappearance or blending. A new conservation strategy is required. An analysis was performed that allows us to ascertain the loss or gain of genetic diversity if one or several subpopulations are removed. The results are compared with those using the Weitzman method. The two methodologies produce conservation priorities that are completely different, the reason being that the Weitzman method does not take into account the within-population genetic diversity. We apply optimal contribution theory and a new procedure for cluster analysis, and discuss their value in the general framework of the problems of setting of priorities and tactics for the conservation of genetic resources.

“…It is widely agreed that genetic diversity can be depicted at molecular level and by the phenotype and the production performance descriptions (Berthouly, et al, 2008;Hillel, et al, 2003;Tixier-Boichard, et al, 2009;Wimmers, et al, 2000). In our previous study (Andres, et al, 2008), we stated that among 7 breeds and varieties the significantly highest proportion of yolk in the egg was from the Lilliputians from Pilchów.…”

“…The decision to classify a given population as a genetic resource should be drawn from its distinctiveness within a species, particularly expressed by genetic distance (Wimmers, et al, 2000). If the separateness between the representatives of bantams and large fowl is clear even on the basis of appearance, the determination of the relatedness between large local varieties of chickens and utility breeds must be revealed by the molecular markers genotyping.…”

The study was aimed at evaluation of the applicability of selected microsatellite markers in examining genetic diversity in five Polish local chicken varieties (two groups of native crested chickens, crestless native chickens from Subcarpathian region and two groups of native miniature chickens) and reveal their genetic relationships to five purebreds (Leghorn, Rhode Island Red, Sussex, Greenleg Partridge, Minorca). About 22.8% (overall F ST = 0.228) of the genetic variation was explained by differences between breeds and varieties. The D A genetic distances between five Polish native varieties and five purebreds varied between 0.154 and 0.440. The results obtained in this study indicate the great value of the collection and suggest the need for formal protection of these local Polish chicken varieties.Keywords: genetic diversity, local chickens, microsatellite polymorphism Streszczenie Celem pracy była ocena przydatności wybranych markerów mikrosatelitarnych do określenia zróżnicowania genetycznego pięciu polskich lokalnych odmian kur (dwóch grup krajowych kur czubatych, lokalnych kur z Podkarpacia, dwóch grup krajowych kur karłowatych) oraz przedstawienie zależności genetycznych tych odmian w stosunku do pięciu ras (leghorn, rhode island red, sussex, zielononóżka kuropatwiana, minorka). Około 22,8% całkowitej zmienności genetycznej (F ST = 0,228) wynikało z różnic pomiędzy rasami i odmianami. Dystanse genetyczne D A pomiędzy pięcioma lokalnymi odmianami a pięcioma rasami przybierały wartości od 0,154 do 0,440. Uzyskane wyniki wskazują na dużą wartość kolekcji polskich lokalnych odmian kur oraz sugerują potrzebę objęcia ich formalną ochroną. 11Journal of Central European Agriculture, 2013, 14(1), p.11-22 DOI: 10.5513/JCEA01/14.1.1147Słowa kluczowe: kury lokalne, polimorfizm mikrosatelitarny, zróżnicowanie genetyczne Detailed abstract Celem pracy była ocena przydatności wybranych markerów mikrosatelitarnych do określenia zróżnicowania genetycznego pięciu polskich lokalnych odmian kur (dwóch grup krajowych kur czubatych, lokalnych kur z Podkarpacia, dwóch grup krajowych kur karłowatych) oraz przedstawienie ich zależności genetycznych w stosunku do pięciu ras (leghorn, rhode island red, sussex, zielononóżka kuropatwiana, minorka). W tym celu zastosowano 10 wysoce polimorficznych markerów mikrosatelitarnych. Łącznie wykryto 62 allele, z których 15 było unikalnych. Około 22,8% całkowitej zmienności genetycznej (F ST = 0,228) wynikało z różnic pomiędzy rasami i odmianami. Wartości średniej liczby alleli, heterozygotyczności obserwowanej i oczekiwanej, indeksu stopnia polimorfizmu (PIC) oraz współczynnika inbredu (F IS ) oszacowane łącznie dla pięciu polskich odmian lokalnych były wyższe niż dla pięciu ras czystych. Dystanse genetyczne D A pomiędzy lokalnymi odmianami, wynoszące od 0,110 do 0,381, wskazują na wyraźną odrębność tych odmian za wyjątkiem dwóch grup kur czubatych. Dystanse genetyczne D A pomiędzy pięcioma lokalnymi odmianami a pięcioma rasami przybierały wartości od 0,154 do 0,440. Uzyskane wyniki...
