Narrative
‘PVL01’, a Provisia (BASF, Ludwigshafen, Germany) long-grain rice (Oryza sativa L.) cultivar, was developed by the Louisiana State University Agricultural Center at the H. Rouse Caffey Rice Research Station (HRCRRS) near Crowley, LA, and approved for release by the director of the Louisiana Agricultural Experiment Station in 2017. PVL01 is the first rice variety to be released as part of the Provisia Rice System (BASF) with resistance to Provisia herbicide, which contains the active ingredient quizalofop, an AACase (group 1) herbicide. PVL01 was derived from the cross ‘CHENIERE’/BASF1-5 (Provisia-resistant mutant) that was made in 2012 at the HRCRRS and advanced in 2014 as an F2:F3 row based on agronomic characteristics. Testing in the Provisia Preliminary Yield (PVPY) trial in 2014 and the Provisia Multi-location Test in 2015 indicated good yield potential and favorable agronomic characteristics. In 2016 and 2017, PVL01 was evaluated in 14 replicated trials across seven locations in Louisiana. Four high yielding, long-grain, commercial varieties were included as checks, ‘CL111’ (PI 658538), ‘Cheniere’ (PI634719), ‘Cocodrie’ (PI606331), and ‘Mermentau’ (PI665688). Grain yield of PVL01 was 7.5 T ha−1 compared with 7.6 T ha−1 for CL111, 8.3 T ha−1 for Cheniere, 6.8 T ha−1 for Cocodrie, and 7.5 T ha−1 for Mermentau. Plant height for PVL01 was 93 cm, which was 1 cm taller than Cheniere, CL111, and Mermentau and 2 cm taller than Cocodrie. PVL01 reached 50% heading in 87 days, which was four days later than Cocodrie and Cheniere, six days later than Mermentau, and nine days later than CL111. The leaves, lemma, and palea of PVL01 are glabrous, and the spikelet and apiculus are straw-colored. PVL01 is very susceptible to blast (Magnaporthe grisea), susceptible to sheath blight (Rhizoctonia solani) and bacterial panicle blight (Burkholderia spp), and moderately resistant to Cercospora spp.
