This study analyzes factors influencing pollen production in inbred maize (Zea mays L.) lines, focusing on genetic material and plant density. Trials in Brăila, Romania (2024), tested six lines across three densities (95k, 135k, and 160k plants/ha). Results indicated that density had no statistically significant effect on flowering time (p = 0.927) or tassel branching. However, significant genotype-specific differences were found. The Zeta V43 line exhibited the highest number of tassel branches (up to 13.0), while Epsilon V81 achieved the maximum main axis length (42 cm) and the highest pollen dry weight (76.80 g) at 115,000 plants/ha. Tukey HSD tests confirmed a significant genotype × density interaction, showing that while Zeta V43 branching improves at lower densities, Epsilon V81 excels in pollen output at medium densities. These findings suggest that genetic selection is the primary driver for tassel development, identifying Epsilon V81 and Zeta V43 as superior candidates for breeding programs aimed at optimizing pollen-producing capacity in hybrid seed production.
