Insights into the genetic diversity of Indian cardamom [Elettaria cardamomum (L.) Maton]: for a future research perspective

A comprehensive assessment of genetic diversity in Indian cardamom (Elettaria cardamomum) reveals significant variability among 196 germplasm accessions, particularly in morphological and biometric traits, as well as yield potential. The study, conducted over three years (2016–2018), identified distinct markers such as compound panicle types, terminal panicle bearing, narrow leaf types, and dark green bold capsules with high-yield potential. These findings highlight the rich genetic diversity present in cardamom populations across the Western Ghats of India and Sri Lanka's Central Highlands, underscoring its potential for breeding region-specific varieties resilient to biotic stress. The research, part of the All India Coordinated Research Projects on Spices, emphasizes the importance of germplasm conservation for future crop improvement efforts.
