| Background and Objective: To select the best and stable hybrid via agronomy attributes. So, this project assesses the best hybrid through plant height, ear height, rows per ear, ear diameter, cob diameter, kernel depth, grains per ear, 1000-grain weight, ear yield, and grain yield at the Moghan climate was performed. Materials and Methods: The experiment based on a randomized complete block design was carried out with four replications during two growing seasons at the Moghan Agriculture Research Station. Results: Compound analysis for agronomy attributes indicated that the interaction effect of year × hybrid on the plant height, grains per ear, ear diameter, and 1000-grain weight was significant. Grain yield and ear yield just was significant between hybrids (p< 0.05). The Correlation between grain yield with ear yield and grains per ear had a positive association. According to biplot analysis, hybrid No. 3 (K47/2-2-1-4-2-1-1-1× MO17) and hybrid No. 7 (KLM77021/4-1-2-1-2-4-1× K47/3) via grain yield, ear yield, and grains per ear, and also hybrid No. 5 (KLM82010(1) × K3640/3) and hybrid No. 9 (SC647) via 1000-grain weight, rows per ear, ear diameter, plant ear, and plant height were the best corn hybrids in this study. The cluster analysis was classified 11 corn hybrids into two different groups. Conclusion: Hybrid No. 7 (KLM77021/4-1-2-1-2-4-1× K47/3) was the best stable corn hybrid for the Moghan climate. It can be used grains per ear and ear yield with grain yield, which were introduced by a heat map to cluster and select the best corn hybrids. | ||
