Background and Objective: Maize/soybean multiple cropping was applied to increase productivity of maize and soybean altogether in West Java, Indonesia. The objectives of the research was to estimate the combining ability of the parental inbred lines of Indonesian maize and to select their hybrids which suitable for intercropping with soybean. Materials and Methods: An experiment was set up in Arjasari-Kabupaten Bandung, West Java from December, 2015 up to March, 2016 to study combining ability and to screen new maize hybrid and their parental inbreeds for multiple cropping with soybean. To study the genetic materials, they were planted based on split plot arrangement. This was replicated twice with the main plot consisting of maize sole cropping and maize/soybean multiple cropping, whereas, the subplots were one hundred twenty four genotypes. Results: Inbreed #1 was the best combiner for early maturity, plant height and seed weight per plant. There were11 hybrids adapting to cultivate under maize/soybean multiple cropping based on LER, CRm, CRs and STI and performing higher seed weight per plant than commercial hybrids. Those hybrids were hybrid 24, 26, 40, 56, 61, 62, 75, 78, 81, 90 and #100. Conclusion: These hybrids were suggested to be evaluated for their stability and adaptability under maize/soybean multiple cropping for different location and seasons.
