Oat - Reins (IL06-5433) - Spring Oat Cultivar Description

Sep 17, 2026

Reins is a spring oat (Avena sativa) cultivar developed by the University of Illinois Agricultural Experiment Station and released after testing as IL06-5433 in 2015. Selection prioritized early maturity, high test weight, lodging resistance, and moderate plant height. The cultivar shows tolerance to barley yellow dwarf virus and resistance to loose smut, with specified responses to crown rust by race. Adapted to Illinois and surrounding Midwest states, Reins was evaluated across multiple years and locations. The document also provides detailed identifying characteristics and guidance on recognized seed classes, certification timing, and PVP application handling.

Oat Reins IL06-5433 (Exp) 1. Reins is a spring oat (Avena sativa) cultivar developed by the University of Illinois Agricultural Experiment Station and owned by the Board of Trustees of the University of Illinois. Reins was tested as IL06-5433 and released in 2015. 2. Reins was selected based on early maturity, high test weight, good lodging resistance and moderately short plant height. Reins has good tolerance to barley yellow dwarf virus and is resistant to loose smut (caused by Ustilago avenae (Pers.) Rostr.). The F2 and F3 generations ofthe cross from which Reins was derived were grown in the greenhouse at Urbana, IL using a modified single seed descent method. 3. Reins is adapted in Illinois and surrounding states (the Midwest Corn Belt). It is expected that it will perform well in Indiana, Illinois, and Iowa and possibly further east. Reins was evaluated in the Uniform Midseason Oat Performance Nursery in 2011, 2012 and 2013 and was evaluated in trials at three locations (Urbana, DeKalb and Monmouth) in Illinois from 2010-2015. 4. Reins is tolerant to barley yellow dwarf virus (BYDV) . Reins is moderately resistant to moderately susceptible to crown rust (caused by Puccinia coronata Cda.f. sp. avenae Eriks.) depending upon races present at a location. 5.

Recognized classes of Reins are breeder, foundation, and certified. There is no registered class of seed. Indiana Ag Alumni has produced Foundation seed and will maintain the cultivar in consultation with the University of Illinois oat breeder. A research assessment fee of $0.30 per bushel will be collected on the Certified class of seed. For seed produced in other states, the fees will be shared 50:50 with that state. One-half of the fee should be returned to Illinois Crop Improvement Association (fee collection agent for Illinois) . 7. Certified Seed will first be offered for sale by seedsmen following harvest in 2016 (about July 2016). Indiana Ag Alumni has sold Foundation Seed for planting in spring 2016. 8. PVP will be applied for and the “Certification Option” will be selected. Descriptive data may be supplied to the PVP database, but will be submitted by the breeder as part of the PVP application. 9.
