Maize (Zea mays L.) is the main food commodity in Indonesia, and it has a strategic role as a food source, industrial raw material, and bioenergy. This research aims to develop superior hybrid corn varieties that are of high quality and are productive. The research was conducted from May to September 2024 in the experimental field of PT. SKAS, Slawu, Patrang, Jember. The research method used a Randomized Complete Block Design (RCBD) with five cross treatments (G01xR1, G02xR1, G03xR1, G04xR1, and G05xR1) repeated three times. Observation parameters included: paddy harvest weight, dry cob weight, cob length, number of kernels per row, cob diameter, number of rows per cob, yield, 1000-grain weight, yield potential (tons/ha), germination, and sprouting speed. Data analysis was carried out using SPSS software with the F test, followed by the Honest Significant Difference (HSD) test at the 5% level for parameters that showed significant differences. The results showed significant variation in yield performance and seed quality of the five crosses. The combination of G01xR1 and G02xR1 showed the best performance, which was uniform and stable as indicated by qualitative parameters (silk color, kernel color, and kernel shape). G01xR1 and G02xR1 had high yield potential of 7.24 tons/ha and 7.26 tons/ha, high yield, and 1000-grain weight of 67.53% and 57.17%, 1000-grain weight (292.67 grams and 253.44 grams), and the number of rows of G02xR1 was 13,9 rows
