Registration of ‘CL152’ Rice

'CL152' (Reg. No. CV-141; PI 666059), a Clearfield (BASF, Ludwigshafen, Germany) long-grain rice (Oryza sativa L.) cultivar, was developed by the Louisiana State University Agricultural Center at the Rice Research Station near Crowley, LA, and approved for release by the director of the Louisiana Agricultural Experiment Station in 2011. CL152 was derived from the cross TACAURI/3/CYPRESS//L-202/TEBONNET/4/CL161 that was made in 2003 at the Rice Research Station. CL152 originated in 2005 as an F-2:3 line selected based on agronomic characteristics. Testing in the Clearfield preliminary yield trials in 2010 indicated high yield potential and favorable agronomic characteristics. In 2009 and 2010, CL152 was evaluated in 38 statewide yield performance trials, along with two, high-yielding Clearfield check cultivars, 'CL111' and 'CL151.' Grain yield of CL152 was 8.7 Mg ha(-1) compared with 8.7 and 9.2 Mg ha(-1) for CL111 and CL151, respectively. Plant height for CL152 was 101 cm compared with 101 cm and 100 cm for CL111 and CL151, respectively. CL152 reached 50% heading in 83 d while CL111 reached 50% heading in 77 d and CL151 in 81 d. CL152 has a semi-erect flag leaf, and the leaves are dark green and display an intermediate leaf angle. The lemma and palea are straw-colored and glabrous, and the apiculus, light purple at heading, is colorless as the grain approaches harvest maturity. CL152 is susceptible to sheath blight disease, moderately resistant to blast disease and moderately resistant to straighthead disorder.
