GT-421CGS is a very good standing, glyphosate/STS, wide-body variety. It’s quick to get out of the ground and canopy the rows, and does not shatter. The disease package is strong with the cyst nematode resistance and phytophthora tolerance to protect its yield potential.

Key Strengths

  • Rapid emergence
  • Cyst nematode resistance
  • Wide plant type
  • RR and STS
  • Adaptable to different row widths

Management Tips

  • Top performance under various populations
  • Yields well even under stress
  • Good defensive characteristics
  • Will work well in your row planter or drill
