Variety traits
Zea mays L. subsp. mays (Maize Group)
The ability of maize hybrids to maintain the stability of physiological processes and develop at suboptimal temperatures below +8…+10 °С.
In the reference 13 varieties crop Maize, where this is mentioned in the description.
Cold-tolerant maize hybrids are capable of germinating at soil temperatures of +6…+8 °С, whereas less resistant varieties require +10 to +12 °С for this purpose. This trait is evaluated using the cold germination method, which includes an analysis of laboratory germination rates, seedling morphometry, and biochemical indicators, such as free proline content.
This characteristic allows for sowing 10–15 days earlier than usual, which ensures faster emergence by 5–7 days and more efficient use of spring moisture reserves. Cold tolerance is not synonymous with frost resistance; therefore, at temperatures below -3…-4 °С, irreversible tissue damage occurs regardless of the hybrid's level of tolerance.
General information about the subject — on the page Cold 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.
