Variety traits
Zea mays L.
Maize tolerance refers to the ability of a genotype to maintain productivity under stress factors such as drought, salinity, temperature fluctuations, and high plant density.
In the reference 721 varieties crop Maize, where this is mentioned in the description.
To quantify maize tolerance, stress resistance indices are used, based on a comparison of hybrid yields under stress and favorable conditions, including the Tolerance Index (TOL), Stress Tolerance Index (STI), and Stress Susceptibility Index (SSI). These indicators allow for the ranking of breeding material based on their ability to maintain stable productivity.
Assessment methods include field trials with controlled moisture deficits as well as laboratory analyses. These include fluorimetry to evaluate the state of the photosynthetic apparatus, the cold germination test to determine seed cold tolerance, and biochemical monitoring of the activity of enzymes such as peroxidase and catalase, which respond to stress.
When studying tolerance to specific factors, such as high density or shading, morphological changes are analyzed: development dynamics from emergence to flowering, plant height, and ear parameters. The use of tolerant hybrids allows agronomists to minimize grain losses and ensure yield stability in high-risk agro-climatic zones.
General information about the subject — on the page Tolerance.
Selection based on the description text, not on official evaluation: these data are absent from registers. For specific variety details, please refer to its profile.
