The aim of this research was to analyse the agronomic characteristics of a maize variety consisting of 20 inbred lines, which are used as germplasm sources for hybrid maize production at SCDA Lovrin. The statistical analysis and interpretation of the results were carried out using IBM SPSS software. Descriptive statistics, including mean, median, standard deviation, minimum, and maximum values, were calculated. To evaluate the significance of the differences, ANOVA and Duncan's multiple range tests, as well as Kruskal-Wallis and Mann-Whitney U tests, were performed. Pearson correlation coefficients and regression lines were determined to study the relationships between variables. The results indicate significant differences between the studied traits, such as leaf color, leaf orientation, anther color (tassel), silk color, ear position (degree), total number of leaves, number of leaves up to the main ear, and number of tassel branches. Additionally, a linear correlation was observed between the number of growing degree days (GDD) to flowering/silking and the total accumulated GDD until flowering/silking.
