Abstract
This thesis integrated agro-morphological, metabolomic, and sensory analyses to evaluate and differentiate Arabica coffee varieties. Field trials of 16 commercial varieties in northern NSW revealed substantial phenotypic diversity and identified semi-dwarf, high-yielding alternatives to the dominant K7, recommending PARAINEMA, MARSELLESA, IPR107 and PARAISO. Untargeted LC-QTOF-MS metabolomics of 20 varieties showed clear genetic-group separation and identified key metabolites underlying quality differentiation. Coupling metabolomics with sensory cupping further revealed compounds associated with specialty grade variation. Collectively, the results provide a multidimensional framework for variety selection, quality improvement, and the development of objective, metabolite-based tools for authentication and flavour profiling.
