The goal of this study was to look at agronomical trait variation in 39 herbicide-tolerant M3 and 37 M4 maize lines from March to July 2015 and September 2015 to January 2016. The experiment used a randomised complete block in triplicates. Plant height, ear diameter, hundred seed weight, ear length, grains row-1 and ear-1, total ears plant-1, yield plant-1, ear height, and herbicide tolerance were all collected. The data was examined using Genstat 16th edition at a 5% level of significance. Except for rows ear-1 and total ears plant-1, the results revealed significant (p0.05) differences between M3 and M4. The most productive M3 a Lines 520-58 and 520-38 3 yielded 116.2 g plant-1 and 151.1 g plant-1, respectively, but yielded less than check varieties (165.3 g) and (183.5 g). The most herbicide tolerant M3 and M4 lines were 513-12 and 520-38_3, which took 25 and 28.5 days to die, respectively. Grain yield plant-1 correlated significantly and positively with the majority of traits in M3, whereas it correlated significantly and positively with 100 seed weight, grains row-1, and total ears plant-1 in M4. Furthermore, tolerance days had a negative and highly significant correlation with plant height and ear height. Plant-1 grain yield was negatively and significantly correlated with herbicide tolerance.
