Abstract

‘CL272’ (Reg. No. CV-149, PI 677004), a Clearfield (BASF, Ludwigshafen, Germany) medium-grain rice (Oryza sativa L.) cultivar, was developed by the Louisiana State University Agricultural Center at the H. Rouse Caffey Rice Research Station (RRS) near Crowley, LA, and approved for release by the Director of the Louisiana Agricultural Experiment Station in 2015. CL272 was derived from the cross ‘Neptune’//‘Bengal’/‘CL161’ that was made in 2009 at the RRS and advanced in 2011 as an F3 row selection. Testing in the Clearfield preliminary yield trials in 2012 indicated high yield potential and favorable agronomic characteristics. In 2013, 2014, and 2015, CL272 was evaluated in 30 replicated trials across six locations in Louisiana. Three high-yielding, medium-grain, commercial cultivars—‘CL271’, ‘CL261’, and ‘Jupiter’—were included as checks. Grain yield of CL272 was 9.1 t ha-1 compared with 9.3 t ha-1 for CL271, 8.2 t ha-1 for CL261, and 9.2 t ha-1 for Jupiter. Plant height for CL272 was 97 cm, which is equal to CL261 and 2 cm taller than CL271 and Jupiter. CL272 and CL271 reached 50% heading in 87 d, while CL261 reached 50% heading in 84 d and Jupiter in 88 d. The leaves, lemma, and palea of CL272 are glabrous, and the spikelet and apiculus are straw-colored. CL272 is moderately resistant to Cercospora and moderately susceptible to bacterial panicle blight, sheath blight, blast disease, and straighthead disorder.
