Pluto F1 hybrid is a Cucurbita moschata type butternut with medium sized fruit and excellent fruit quality. Plants are adaptable and vigorous and tend therefore to be less susceptible to diseases. Yield potential is excellent and the fruit is not inclined to crack. Fruit set is excellent and covers a long bearing season. Fruit shape is similar to that of Waltham and the weight is 1 – 2 kg. The firm, deep orange flesh has an excellent flavour and high sugar content. The smooth rind has a tan colour when mature. Mature fruit has an excellent shelf life. Pluto is well adapted for cooler season harvests where small to medium fruit are required. The fruit is used as traditional butternut for the fresh market, however, the superior flesh quality makes Pluto suitable for processing and export. Pluto has intermediate resistance to Powdery mildew (Px) (ex Sf).
