Fruit flavor is a key quality trait associated with consumer preference for muskmelons (Cucumis melo L.) A wide range of aroma compounds play a key role in the flavor profiles of different melon cultivars. This study evaluated VOC profiles of nine cantaloupe cultivars grown in different locations (Texas, Arizona, Georgia, California, North Carolina and Indiana) across the United States during the spring production season (2018). Two consumer-preferred commercial cultivars were purchased and considered as control fruits for comparison. Significant variation in VOC contents was observed among the cultivars and growing locations. The highest and lowest total volatiles were detected in F-39 from GA and TT-DV from TX, respectively. Ketones such as geranylacetone, β-ionone, β-ionone epoxide, and dihydroactinidiolide were the major VOCs in all the cultivars. Principal component analysis (PCA) and Random forest analysis revealed significant clustering among the cultivars based on growing location demonstrating that suitable cantaloupe cultivars for different growing regions can be selected base on this important consumer-preference quality trait.
