CLL20 (NEW)

RAISING THE BAR FOR CLEARFIELD GRAIN QUALITY.

CLL20 is a long grain Clearfield® variety developed by the LSU AgCenter. It produces low-chalk, clean grain built for premium-quality markets, carries the Pi-ta blast-resistance gene and reaches 50% heading in about 80 days. In trials, CLL20 delivered higher whole grain yields than CLL18 and higher second-crop yields than both CLL18 and CLL19, giving growers a Clearfield option that holds up at the mill.

  • This variety has genetic markers for Pi-ta, which confers resistance to the following blast races: IA45, IB1, IB49, IB54, IB45, IH1, IG1, IC17, IE1.

*Reactions may differ due to variability of strains among pathogens.

  • 1 Height will vary with plant density and environmental conditions.
  • 2 Maturity varies with geographical region and environmental conditions in a given year.
  • 3 Seed/lb is not an exact number; it is an average from multiple samples harvested over a wide geography.
  • 4 Optimal drill-seeded planting rate is only for fungicide treated seed. If using non-treated seed, the seeding rate should be increased by a minimum of 10 lb/A.
  • 5 Optimal nitrogen rate varies from field to field. The high end should be reserved for heavy clay soils and fields where rice is followed by rice. Using the high end of the nitrogen and seeding rate recommendations may increase the incidence of disease. Please scout and treat the Clearfield® varieties accordingly. The NSt*R program is recommended where applicable and has been shown to decrease incidences of disease and lodging. Please contact your local Cooperative Extension office for more information.
