Abstract: The investigation entitled “Molecular variations in Teak (Tectona grandis L. f.) clones†was carried out at Rajpipla Silviculture Forest Division, Rajpipla and Biotechnology Laboratory, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari (Gujarat). The experiment comprised of 15 clones viz., C1-Bandhpada (North Dangs), C2-Chikhli (South Dangs), C3-Nilambo (Dungarda), C4-African (Dungarda), C5-Satkhasi (Vyara), C6-Khalta (Bariya), C7-Achhala (Godhra), C8-Kevadi (Chotaudepur), C9-Raighadh (Sabarkantha North), C10-Danta (Banaskantha), C11-Vanaj (South Sabarkantha), C12-Dankiwadu (Gir West), C13-Bhavnath (Junaghadh), C14-Develvel (Gir East) and C15-Khatam (Rajpipla East). This experiment was laid out in Randomized Block Design (RBD) comprising of fifteen clones and three replications. The seven decamer primers produced a total of 50 scorable bands in the fifteen clones of Tectona grandis L. f. out of them 20 were polymorphic and 30 were monomorphic. The percentage of polymorphism ranged from a maximum 50.00 % by OPE-18 to a minimum of 16.67 % by OPE-10. The lowest genetic similarity (0.7209) was between the clones 4 & 7 whereas the highest genetic similarity (0.9761) was between the clones 9 & 10. The dendrogram of fifteen clones reflected that the clones were divided in two main clusters named A and B. Further Cluster-B was divided in to two sub clusters B1 and B2. The clones C7 and C8 reported in Cluster-A which were found to be more diverse as compared to other clones. The clones C1, C3, C5, C2, C6 and C4 were observed in sub-cluster-B1. Whereas, clones C9, C10, C15, C11, C12, C13 and C14 were recorded in sub-cluster-B2. The clones C4 and C14 found in B1 and B2 sub-cluster, respectively which having minimum similarity with other clones.
