為評估臺灣豐和黑毛烏骨雞選育族群的遺傳變異，本試驗利用 FAO（2011）建議使用的 24 組雞微衛星標記組分析 48 隻臺灣豐和黑毛烏骨雞第 G5 世代種雞個體 DNA。24 組微衛星標記皆有多態型的基因型。共檢測到 89 個對偶基因，平均每個基因座具有 3.7 個對偶基因（2~9 個），其期望異質度介於 0.010 到 0.828，平均為 0.517，觀測異質度介於 0 到 0.688，平均為 0.408，而多態性訊息含量平均為 0.452。在選用的 24 組微衛星標記組中有 10 組呈現高度多態性資訊（PIC ≥ 0.5），有 11 組呈現中度多態性資訊（0.5> PIC ≥ 0.25），3 組呈現低度多態性資訊（PIC < 0.25）。本結果提供此選育族群遺傳變異之基本分子資訊。
關鍵語：黑毛烏骨雞、遺傳多樣性、微衞星遺傳標記

In order to evaluate genetic variation of TW Fengho black silkie chicken flock. we use a set of 24 microsatellite markers recommended by FAO to analyze 48 candidate bred chickens from this flock. All the microsatellites were polymorphic. The average allelic number was 3.7, ranged from 2 to 9 per locus. The expected heterozygosity ranged from 0.010 to 0.828, and the average expected heterozygosity was was 0.517±0.187(mean±SD). The observed heterozygosity of the population ranged from 0 to 0.688, and the average observed heterozygosity was 0.408±0.213. The estimated average polymorphic information content (PIC) was 0.452±0.171. In 24 markers, ten markers were highly informative with polymorphism information content (PIC ≥0. 50), eleven markers were reasonably informative(0.5> PIC≥ 0.25) and the other three markers were slightly informative (PIC < 0.25). These results could be provided basic molecular information for the research on the germplasm characteristics of the population.
