Abstract
Maize hybrids have developed more than one ear at a single node in farmers’ fields of Jayavaram village, Siricilla district of Telangana during kharif, 2019. This trait has been expressed in different ways. In the most extreme cases, up to 6 to 8 ears have occurred at a single node, we can call it as 'bouquets'. Bouquet ears are often formed at the node below where the primary ear arises. This indicated that stress at V5 or V6 (i.e., nutritional deficiency, water logging conditions) stopped normal development of the primary ear, thereby breaking apical dominance. Breaking of apical dominance, may contribute to multiple ears developing at the same node or its due to problem in pollen shedding from tassels, (especially in kharif season due to continuous rains) male inflorescence at the time of flowering or increase in Anthesis Silking Interval. It causes a drastic reduction in grain yield and quality which ultimately leads to lower profitability.
