Interpretive Summary: FL12034-10, developed and tested by the University of Florida, was released in October 2022 as an oat cultivar suitable for either spring or fall planting. It grows well across the southern US, from Texas to North Carolina, and provides producers with a medium-tall, mid-season, awnless, white-glumed, dual-purpose oat that has high yield potential, good straw strength, and good forage yield. The line possesses a semi-prostrate growth habit, vigorous growth and high tillering capacity, and has large leaves that are dark green in color. It expresses moderate to high levels of resistance to most diseases prevalent in the southern US. The grain yield average is competitive with check varieties that are widely used in the southern part of the US. The forage yield was higher than most of the checks. FL12034-10 demonstrated better lodging and disease resistance, higher grain yield potential, and higher mid-winter to late spring season forage yield potential than oat varieties (Horizon720 and Legend567) recently released by the University of Florida.

Technical Abstract: FL12034-10 (Reg. no.___, PI ___), a facultative oat (Avena sativa L.) cultivar, developed and tested by the University of Florida, was released in October 2022. FL12034-10 was derived from a three-war cross LA06055SBSBSB-79/FL11048 F1. It is well adapted, from Texas to North Carolina, and provides producers with a medium-tall, mid-season, awnless, white-glumed, dual-purpose oat that has high yield potential, good straw strength, and good forage yield. FL12034-10 was observed to be uniform and stable across environments in the southern US from 2016 to present. The line possesses a semi-prostrate growth habit, vigorous growth and high tillering capacity, and has large leaves that are dark green in color. It expresses moderate to high levels of resistance to most diseases prevalent in the southern US. The crown (CR) and stem (SR) rust and Barley yellow dwarf virus (BYDV) ratings of FL12034-10 were 1.7 (14 environments), 0.7 (8 environments), 1.5 (5 environments), and 3.7 (2 inoculated BYDV nursery), respectively. The disease ratings were better than most of the checks. The grain yield average of FL12034-10 from 41 environments during 2018-2021was 6437 kg ha-1 which is competitive with check varieties that are widely used in the southern part of the US. The forage yield of FL12034-10 ranged from 2358 to 6617 kg ha-1 (20 environments) which was higher than most of the checks. FL12034-10 demonstrated better lodging and disease resistance, higher grain yield potential, and higher mid-winter to late spring season forage yield potential than oat varieties (Horizon720 and Legend567) recently released by University of Florida.
