Tolerance — Sweet Corn

Zea mays L. subsp. mays (Sweet Corn Group)

The ability of sweet corn hybrids to maintain productivity and growth under abiotic and biotic stress conditions. It is evaluated by comparing yields under stress relative to a control using mathematical indices and scoring scales.

In the reference 38 varieties crop Sweet corn, where this is mentioned in the description.

To evaluate sweet corn tolerance, calculated indices such as STI (Stress Tolerance Index), SSI (Stress Susceptibility Index), and mean productivity metrics are used. These allow for the quantification of a specific genotype's ability to minimize yield reduction during drought, shading, or high plant density.

When evaluating biotic factors, such as damage by the European corn borer, a scoring scale from 1 to 5 is used, reflecting the degree of plant resistance to the pest's negative impact. The level of tolerance is determined exclusively in comparison with other genotypes under similar experimental conditions.

This metric is of critical importance for sweet corn agronomy, enabling the effective selection of hybrids for conditions with increased plant density or a high risk of stressful weather events. High tolerance ensures a stable output of marketable produce and reduces reliance on chemical protection agents.
