European corn borer (Ostrinia nubilalis Hbn.) in maize crops of the uman district

confirmed Kadet's advantage with the highest germination rate (93 1.1 %), germination energy (88 1.0 %), and the shortest germination duration (4.2 0.1 days), all with the lowest variability (CV = 1.18 %, 1.14 %, and 2.38 %, respectively).Kadet also exhibited the highest seed density (1.18 0.01 g/cm) and uniformity (95 1.2 %).Seed weight analysis revealed that Kadet had the largest 1000-seed weight (2.71 0.06 g) compared to Boyarin (2.69 0.08 g) and Husar (2.66 0.09 g), with the lowest CV (2.21 %).Biochemical profiling confirmed Kadet's dominance in oil content (50.2 0.5 %) and total protein (19.7 0.2 %), as well as in crude protein content (18.6 0.5 %), again showing minimal variation (CV = 1.00-1.02%).Overall, cultivar Kadet consistently outperformed the other genotypes across all analyzed parameters, including seed morphology, physiological viability, and nutritional composition.Its high stability and superior metrics make it a promising candidate for further breeding, industrial oil production, and cultivation under variable climatic conditions.Boyarin and Husar exhibited moderately lower values and higher variability, with Husar being the least favorable under laboratory testing conditions.
