Variety traits
Zea mays L.
The female reproductive organ of maize, the morphometric parameters of which determine the productivity of a hybrid and its technological suitability for mechanized harvesting.
In the reference 2 356 varieties crop Maize, where this is mentioned in the description.
To evaluate the breeding value of hybrids, measurements are taken of ear length and diameter, number of grain rows, grain weight per ear, and grain shelling percentage. An important indicator is the ear attachment height from the soil surface, which must be at least 50 cm to ensure high-quality mechanized harvesting by combines without losses.
Quantitative parameters of the ear are genetically determined but are subject to environmental influence. Ear abortion during the initiation period, which occurs at the 8–10 leaf stage, can be caused by temperature stress and lead to the absence of fertile ears and a significant reduction in yield.
General information about the subject — on the page Ear.
