Abstract: Because of poor disease resistance and fruit aroma of Fragaria×ananassa with narrow genetic background, the promising cultivars are difficult to select. Utilizing interspecies crossing with wild germplasm can be a breakthrough in the breeding program. Fragaria nilgrrensis is widely distributed in southwest China, covering northwestern regions of Yunan, and southern regions, eastern regions, middle regions and northeastern regions of Sichuan. Fragaria nilgrrensis has genetic diversity and can produce different aroma profiles in different environments. The unique peach flavor produced from Fragaria nilgrrensis might be influenced by volatility esters, alcohol and terpene. In this review, the aroma compound, which is related to ester synthase, terpene synthase and terpene biosynthesis pathway in different plants, are discussed. The results indicate that the ester and terpene biosynthesis are complex and play an important role in the aroma formation in plants. Therefore, utilizing interspecies crossing with Fragaria nilgrrensis can improve fruit flavors.
