Registration of ‘PVL01’ Rice

Abstract

‘PVL01’ (Reg. no. CV‐153, PI 682661), a Provisia (BASF) 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 cultivar to be released as part of the Provisia Rice System (BASF) with resistance to Provisia herbicide, containing the active ingredient quizalofop, an AACase (group 1) herbicide. PVL01 was derived from the cross ‘Cheniere’/BASF1‐5 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 Multilocation 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 commercial cultivars were included as checks, ‘CL111’, ‘Cheniere’, ‘Cocodrie’, and ‘Mermentau’. 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. PVL01 is very susceptible to blast, susceptible to sheath blight and bacterial panicle blight, and moderately resistant to Cercospora spp.
