Commercial corn hybrids became expensive for local farmers. Extensive use of corn hybrids since 1980 left numerous obsolete hybrid varieties all over Indonesia. The hybrids became obsolete by the introduction of the new ones. Over time the obsolete hybrids expressed superior traits toward detrimental hindrances in situ such us resistance to pest and disease and drought, required less fertilizers while yielded at par with the new hybrids. The traits were identified, the obsolete hybrids were worthy to select for being local genetic sources (LGS) in a corn breeding program. The research was done to identify the LGS collected from Padang, Palembang, Jogjakarta, West Kalimantan and Lampung. In 2018 the LGS were planted in two rows and open-pollinated among themselves. The seeds were harvested separately to make female lines. A synthetic line was made by mixing 100 seeds of each female line. In 2019 the six lines: five female and one synthetic, and Pioneer36 (P36) Fl-hybrid as control were planted in a randomized complete block design with 3 replicates. The data were collected for traits: plant height, leaf number plant:', time to tasseling, time to silking, ear length, ear diameter, 100 seed weight and seed yield rn". The data were variance-analysed and Tukey's HSD was applied to separate and group the lines. A dendrogram was constructed to decide lines suitable to recombine. The result indicated that the Padang, Palembang, Lampung and Synthetic lines could be used as the male parents to recombine with the Jogjakarta and West Kalimantan lines.
