Exp258 is a traditional non-GMO hybrid that is genetically close to certain genetically modified lines, such as SmartStax. It is used exclusively in agrobiological research as an isoline for studying the effects of insecticidal proteins on organisms and ecosystems.
This material does not have a description of agronomic characteristics, such as maturity group, height, or disease resistance, as it is not intended for commercial cultivation. In variety registers, it is listed as official test material for comparison with commercial hybrids.
