Registration of 'PVL03' rice.

'PVL03' (Reg. no. CV‐159, PI 699656), 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 near Crowley, LA, and approved for release in 2020. PVL03 is the third rice cultivar released as part of the Provisia Rice System with resistance to Provisia herbicide, containing the active ingredient quizalofop‐p‐ethyl, an AACase (group 1) herbicide. PVL03 was derived from the cross 'PVL01'/'Catahoula'. Testing in the Provisia preliminary yield trial in 2018 and the multi‐location trial in 2019 indicated good yield potential and favorable agronomic characteristics. In 2020, PVL03 was evaluated in commercial advanced replicated trials across six locations in Louisiana. Four high‐yielding commercial cultivars were included as checks: 'PVL02', PVL01, 'CL153', and 'Cheniere'. The average grain yield of PVL03 was 9.6 t ha−1 compared with 8.0 t ha−1 for PVL02, 8.1 t ha−1 for PVL01, 9.8 t ha−1 for CL153, and 9.1 t ha−1 for Cheniere. PVL03 was shorter than the previous Provisia cultivar, PVL02. The milled grain length was longer than that of PVL02, with a length‐to‐width ratio of 3.0. It has a typical US long‐grain rice cooking quality with intermediate amylose and gelatinization temperature. PVL03 is moderately susceptible to sheath blight and moderately resistant to leaf blast and bacterial panicle blight. Core Ideas: PVL03 is the third cultivar released for the Provisia rice production system.PVL03 is higher yielding than the previous Provisia rice cultivars.PVL03 has better grain and milling quality than previous Provisia rice cultivars.PVL03 offers broad spectrum resistance to the fungal disease blast.
