Maize (Zea mays L.), one of the most significant and important strategic food crops among cereals, ranks second in productivity but first in production area in Ethiopia. The average yield of the nation and region has grown over time, and hybrid maize varieties have played a significant role. The study's goals are to find high-yielding improved hybrid maize varieties and ascertain the relationship between agronomic traits and grain yield, both directly and indirectly. In the Assosa region of western Ethiopia, thirteen genotypes of maize and two standard checks were assessed in a randomized complete block design with three replications during the 2021 main season. Significant differences (p≤ 0.01) were found between genotypes for the majority of tested traits, according to analysis of variance. According to these, there was enough genetic variability for the traits under test. Grain yield and yield advantage over the standard check were highest for maize genotypes-13, 10, and genotye-12. The number of ear, days to maturity, number of ears, and number of plants per plot were all found to positively and significantly correlate with grain yield. Days to anthesis and days to siliking showed a negative significant correlation with yield. Selection for maximum number of ear, plant and late maturity day’s parallel could result yield improvement in maize. Genotype-13 (8.49 t ha-1), genotype-10 (8.01 t ha-1) and genotype-12 (7.97 t ha-1) had the uppermost grain yields and could be used in future crop maize improvement creativities.
