CLL19

HIGH YIELD POTENTIAL, EARLY MATURING

CLL19, developed in the LSU AgCenter rice breeding program, has very good milling yields and blast resistance. It has demonstrated excellent yield potential over the last four years of multi-location testing and has consistently been the top-yielding semi-dwarf Clearfield variety across trials. CLL19 is earlier than most Clearfield varieties and is shorter-statured, with good stem strength. It also has excellent ratoon crop potential.

  • 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.
