Narrative
'CLL 15' is a high yielding, very early maturing, and short stature Clearfield® (BASF, Ludwigshafen, Germany) long-grain rice cultivar with improved disease package developed by the University of Arkansas Rice Research and Extension Center in Stuttgart, Arkansas (RREC) and approved for release by the Arkansas Agricultural Experiment Station, University of Arkansas System Division of Agriculture in January 2019. It was selected from the cross of RU1302048/RU1302045 made in summer 2013. RU1302048 originated from the cross RUCL 1311Trenasse while RU1302048 came from the cross 9502008A/Drew/4/CFX29//KaybonneUJodon/3/Cypress/KaybonneU/9502008-A. CLL 15 was initiated as a F4 bulk of a single progeny row in the winter nursery near Lajas, Puerto Rico in spring 2015. From 2016 to 2019, CLL 15 was evaluated in 47 multi-location trials. Clearfield® cultivars CL 151 (Pl 654463), CL 153 (Pl 677005) and CL 172 (Pl 674614) served as checks. Grain yield of CLL 15 was 9.33 t ha-1 across all trials compared with 9.50 t ha-1 for CL 151, 8.74 t ha-1 for CL 153, and 8.74 t ha-1 for CL 172. In the statewide multi-location trials in Arkansas namely: Arkansas Rice Performance Trial (ARPT) and Producer Rice Evaluation Program (PREP), CLL 15 consistently produced the highest grain yield ranging from 8.80 to 10.31 t ha-1. Plant height of CLL 15 was 97 cm, which is 2 cm taller than CL 172, but slightly shorter than 101 and 99 cm for CL 151 and CL 153, respectively. CLL 15 reached 50% heading in 83 days, which was similar to CL 151 and two days earlier than both CL 153 and CL 172. Similar with CL 153 and CL 172, CLL 15 is moderately resistant to neck and leaf blast while CL 151 was highly susceptible. CLL 15 together with the check varieties are all susceptible to sheath blight, bacterial panicle blight kernel smut, and false smut. The leaves, lemma, and palea of CLL 15 are glabrous, spikelet is straw colored and apiculus is red or purple at heading.

some seed lots of domesticated rice may contain contaminants of a noxious weed hybrid-form that are not distinguishable by seed visualization, which is responsible for the rice-growing state's noxious-weed seed regulations indicated below
