Each spring I seem to get more and more questions surrounding traits of particular varieties. It seems like an easy thing to figure out, but with the shorter and shorter lifespan of cotton varieties as well as the introduction of new traits and trait packages each year, it has become a more and more common question.
The best way to determine traits of particular varieties is to ask a company representative, but in cotton there is a way to know by understanding the actual cotton variety name.
In each name there are abbreviations which make up variety nomenclature. A guide to the current trait options can be found below. This information can also be found on page 72 of the 2019 Georgia Cotton Production Guide.
