Description Small cardamom (Elettaria cardamomum Maton) contributes a major share in earning India's foreign exchange. Elettaria is a monotypic genus of the family Zingiberaceae cultivated in the evergreen forests of Western Ghats
in South India. Small cardamom being a cross-pol1inated crop exhibits a wide range of variability for many characters of scientific and commercial interest. Genetic variants exist for precocity, panicle emergence, length,position and branching of panicles, number of panicles per tiller, size and shape of leaf length and size of tiller, number of capsules per raceme, size,
shape and colour of matured capsules, essential oil content and resistance
to disease which could be used in further crop improvement programmes.However, the bottlenecks in conservation of cardamom genetic resources are i) purity of accessions in ex-situ conservatory and genebanks in field.ii) under utilization of related genera such as Alpinia and Amomum to
transfer resistance against viral diseases and iii) deforestation and disturbance
to natural habitats of cardamom. Rapidly dwindling area under cardamom and convertion of cardamom area for other remunerative crops like pepper and coffee etc are also posing serious threat to genetic resources of
cultivated types. Detailed study of genetic, cytological and biochemical aspects of variation and evaluation for identifying types with high essential oil content, endurance against drought and pests and resistance against diseases needs to be taken up.
