Abstract The species Cymbopogon winterianus Jowitt is believed to have originated from the well-known species Cymbopogon nardus, type Maha Pengiri, referred to as Ceylonese (Sri Lankan) commercial citronella. Cymbopogon winterianus Jowitt was named after Winter, who raised its population as a separate species in the 19th century. C. winterianus was introduced into Indonesia and became commercially known as the Javanese citronella. The Javanese type C. winterianus material was introduced into India for the commercial cultivation of this crop during 1959. Varieties of this species have been developed later by the use of breeding procedures from the same introduced material. A comparative analysis of yields of herb, oil percentage and oil constituents for eight prevalent C. winterianus cultivars comparing them between themselves as well as against an accession of C. nardus has been carried out. All these accessions were analyzed at the molecular level for the similarity and genetic distances through RAPD profiling, using 20 random primers. More than 50% divergence was observed for all the C. winterianus accessions in relation to C. nardus accession CN2. The clustering based on the similarity matrices showed a major cluster of six accessions, consisting of two sub-clusters. The accession C. nardus CN2 got carved out along with two C. winterianus accessions, CW2 and CW6. On the other hand, the accessions CW2 and CW6 demonstrated distinct identities compared to CN2 at the DNA level.
