In order to study new indigenous early-maturing hybrids of corn to obtain high-yielding lines compatible with the region's climate an experiment was carried out at Miyandoab Natural Resources and Agricultural Research Station. The experimental design was randomized complete blocks with four replications. During of the research, different growth stages were recorded. Simple analysis of variance of yield and yield components was done based on %14 kernel moisture. The results showed that there was significant difference at p≤0.01 among the hybrids in terms of all traits. The hybrids 11, 4 and 7 with 16.20, 15.84, and 15.05 t/ha, respectively, were significantly different from the check. Among the high-yielding hybrids the hybrid 7 has the lowest kernel moisture (18.12 %) that in case of yield stability can favorably be cultivated in the W. Azerbaijan province.
