Tokun : A new decaploid interspecific hybrid strawberry having the aroma of the wild strawberry Yuji NOGUCHI National Agriculture and Food Research Organization National Institute of Vegetable and Tea Science Vegetable Breeding Research Team, -0* Kusawa, Ano, Tsu, Mie, /+.,-3, Japan Abstract Breeding to introduce a new aroma to the cultivated strawberry, F. ananassa, from a diploid wild strawberry, F. nilgerrensis, was tried. A first interspecific hybrid Kurume No. + resembles F. nilgerrensis in aroma components, and the aroma is peach-like. However, it has not gained popularity for commercial production because the appearance of the fruit is bad and the yield is few. A new interspecific hybrid Tokun was developed. The pale yellowish-orange fruit of Tokun is a short cone with excellent skin gloss and a superior overall appearance. The fruit has aroma components of caramel, coconuts, and peach. Tokun will contribute to new development and expansion of demand for strawberries. Key words : F. ananassa, F. nilgerrensis, interspecific hybrid, peach-like aroma, aroma components
