Abstract

This study aimed to obtain the right planting system in a greenhouse-scale oriental makuwauri melon plant breeding program and knowing the interaction between the line and the oriental melon growing system at the greenhouse scale. The research design used a Randomized Complete Block Design (RCBD) with two factors, namely melon lines (ougan makuwauri and ginsen makuwauri), and planting systems (tunnel, bracket pot, and vines rope), repeated four times. Observational data were analyzed using analysis of variance and least significant different (LSD) test at 5% levels. The results showed that the best planting system is the bracket pot. This planting system has a unique and attractive appearance as well as more optimal growth compared to tunnel systems and vines rope. Based on the qualitative variable data tested, namely vine length (122.25 cm), stem diameter (0.79 cm), and petiole length (11.86 cm), the bracket pot planting system was significantly different from the tunnel and vines rope planting system. There was an interaction between the lines and the planting system on the observed variables, namely vine length, number of leaves, leaf width, leaf length, petiole length, and stem diameter. This research indicates that bracket pot planting system is recommended for oriental melon plant breeding program.
