Genetic Variation In Some Natural Populations Of Prunus Africana (hook.f) Kalkman (rosaceae) From Ethiopia As Revealed By Random Amplified Polymorphic Dna (rapd)
Prunus africana (Hook.f.) Kalkman (Rosaceae) is a multipurpose Afromontane tree species which isrnthreatened by over-exploitation and habitat destruction in a number of African countries, includingrnEthiopia. As a result, there is a growing concern of conservation and sustainable utilization of the species.rnUnderstanding of the patterns of variation within and among populations of the species is a prerequisiternfor devising optimum management strategies for its conservation and sustainable utilization. Here,rnrandom amplified polymorphic DNA (RAPD) analysis was used to assess the extent of genetic variationrnand the partition of within and among six populations of P. africana sampled from six differentrngeographical regions of Ethiopia. From the total number of amplified loci, 82.3% revealed to bernpolymorphic for the whole data set. The within population diversity estimated by Nei’s gene diversityrnestimates ranged from 0.307 for Tepi to 0.150 to Bulki, with a mean of 0.234. Genetic differentiationrnbetween populations was estimated with Nei’s GST (0.262) and AMOVA based FST (0.257; P
