In order to evaluate of the agronomic value of crops, four varieties of grain corn along with three suitable check varieties in four different regions (Karaj, Moghan, Jovein and Dezful) have been tested in a randomized complete block design with four replications for two crop years (2022 and 2023). During the cropping season, the data were taken based on the corn VCU guidelines and the grain yield and components of grain yield were evaluated. Simple and combined analysis of variance (ANOVA) were used based on 14% grain moisture content and comparison of means for each region were performed using Duncan's multiple range test method using SAS statistical software. Also, the environmental coefficient of variation was calculated using the Francis and Kanenberg method in different environments. In the combined analysis of years and locations, as well as comparing the average of the varieties in the two-year analysis of each region, the results showed that all four applicant varieties, including Antilla, 1364-99, 1365-99, and GW1129, were superior to the check varieties in terms of higher yield in the combined analysis and in terms of yield stability in separate analysis in different years and locations, and deserve to introduce as a new variety.
