Efforts to increase sweet corn production are carried out by utilizing marginal land equipped with drip irrigation. This effort requires assembling sweet corn hybrid seeds that are suitable for marginal land. Assembling hybrid varieties requires information related to the expected testing of several hybrid lines. The objective of this study is to examine the growth and yield potential of several combinations of F-1 expectation crosses in marginal land use drip irrigation. This study was conducted at the Experimental Garden of Faculty of Agriculture, UPN “Veteran” Yogyakarta. This study used a diallel cross design with three replications. The treatments were 10 numbers of sweet corn consisting of 7/5-1B, KD/1-3, and 50/4-2B as parents, KD/1-3☓7/5-1B, KD/1-3☓50/4-2B, 7/5-1B☓KD/1-3, 7/5-1B☓50/4-2B, 50/4-2B☓KD/1-3, 50/4-2B☓7/5-1B as F1 and the sweet corn variety Talenta for comparison. The observation variable consisted of plant height, number of leaves, stem diameter, ear height, male flowering age, female flowering age, ear length without husk, ear diameter without husk, weight of ear without husk and level of sweetness. Each variable was analyzed using variance with α = 5%. The results showed that the combination of the F-1 hope crosses which has the potential to become a hybrid variety is the combination of 50/4-2BXKD/1-3 crosses.
