Study on Genetic Diversity Based on AFLP Markers on Black Goat in the West of Panzhihua

In this study,AFLP(Amplified Fragment Length Polymorphism) was employed to analyze genetic diversity of 5 black goat populations in Panzhihua.15 primer combinations were used to amplify 1003 polymorphic markers,the average polymorphic frequency is 99.01%.The genetic diversity indexes of the 5 black goat populations are from 0.0136 to 0.2131,the maximum and minimum average genetic diversity indexes are Jianchang(0.1346)and Lezhi(0.1101) respectively.The genetic distance is from 0.0062 to 0.0281.Aa a result,Jianchang and Panzhihua black goats are clustered into a class,Yunling and Lezhi black goats are clustered into a class,the above two classes are clustered into a large one;the large class is clustered with Jingtang black goat into one class.The of AFLP could reflect the influence of environment conditions on genetic diversity.
