Abstract

This experiment was conducted to reveal genetic diversity among 38 genotypes of sugarcane (Saccharum officinarum L.) using RAPD markers. The population consisted of 8 genotypes from Australia, 7 from Africa, 10 from America, and 13 from Asia. Genetic similarity was ranging from 17% to 97% , with the average of 57%. UPGMA dendrograms divided the population into three major groups i.e. group 1, 2, and 3 which consist-ed of 23, 10, and 5 genotypes, respectively. Each major group comprised genotypes of different geographical origins. The dendrogram divided each group into some subgroups. There were 8 subgroups i.e. 4 subgroups in group 1, 2 sub-groups in group 2, and 2 subgroups in group 3. Some genotypes of same geographical origin were clustered into in at least 3 different sub-groups, meaning that they were genetically dis-similar. On the other hand, some other geno-types of different geographical origin were clus-tered into the same subgroup, meaning that they were genetically similar. This data would help su-garcane breeders to select parents for hybri-dization in order to maximize heterosis. This could be conducted by selecting parents of dis-similar genotypes. Keywords: diversity; RAPD; sugarcane
