Butternut pumpkin (Cucurbita moschata(Duchesne) Poir ‘Butternut’) is a nutrient-rich horticulture plant which provide a high economic value. To meet the market’s demand, butternut pumpkin must has a prime and maximum phenotypic characters both in quantityand quality. This research aims to examine the phenotypic characters and gene interactions that occurs in butternut pumpkin. Butternut pumpkin were cultivated in two different places (screen house and agricultural land) and using two different seed, cultivated seeds by Laboratory of Genetics and Breeding in Faculty of Biology Universitas Gadjah Mada (noncommercial) and Panah Merah seeds (commercial). Observation of phenotypic character was carried out for 3-4 months starting from planting to harvesting. About thirteen phenotypic characters was analyzed using quantitative data analysis of variance (one way ANOVA) and Chi-Square test. Based on the result, it is known that noncommercial and commercial butternut pumpkin have 10 different quantitative characters. Noncommercial butternut pumpkin has uniform phenotypic characters but unstable in size of plant (stem diameter 1.22 ± 0.21 and 1.37 ± 0.34 cm)and fruit’s shape (dumbbell, pyriform, and disc). Noncommercial butternut pumpkin has dominant epistasis gene interaction with ratio of 12 (dumbbell): 3 (pyriform): 1 (disc). Commercial butternut pumpkin has uniform and stable phenotypic characters with dumbbell fruit’s shape
