1000-kernel weight of maize

Zea mays L. subsp. mays (Maize Group)

A key indicator of maize grain size and plumpness, used for calculating seeding rates and forecasting yield. It depends on the genetic potential of the hybrid and the conditions during the grain-filling period.

In the reference 159 varieties crop Maize, where this is mentioned in the description.

The 1000-kernel weight in maize is determined by the genetic characteristics of the maturity group and growing conditions. Early-maturing hybrids typically have values of 250–300 g, mid-maturing hybrids 300–350 g, and late-maturing or large-seeded hybrids 350–400 g. Under experimental conditions, the range of values can vary from 200–210 g to 400 g.

This indicator is critical for the precise calculation of seeding rates when converting from weight units to the number of viable seeds per hectare. A high 1000-kernel weight indicates a sufficient supply of nutrients in the endosperm, which contributes to improved field emergence and initial plant development vigor. This trait is negatively affected by moisture deficit and extreme temperatures above 35°C during the grain-filling phase, which can reduce the weight by 15–25%.
