Registration of 'Avalon' winter malt barley

Abstract

‘Avalon’ (Reg. no. CV-383, PI 700308) is the first two-row, winter malt barley (Hordeum vulgare L.) cultivar developed by the Virginia Agricultural Experimental Station. Avalon was released in May 2020. Prior to being named, Avalon was tested under the experimental designation VA16M-81. Avalon was evaluated from 2018 to 2023 in the Eastern Malt Barley Trials (EMBT) at one to three locations in three states and in the Winter Malt Barley Trial (WMBT) from 2020 to 2023 in six to 15 states. In the EMBT in Virginia, mean grain yield (5604 kg ha⁻¹) of Avalon was higher to cultivar ‘Violetta’, but lower than those of ‘Flavia’, ‘Calypso’, and ‘Thoroughbred’. Average grain volume weight of Avalon (64.9 kg hL⁻¹) was significantly (P ≤ 0.05) higher than the check cultivars, except Violetta. Head emergence of Avalon was 3 days earlier than Flavia and Calypso and 1 to 2 days later than Violetta and Thoroughbred, respectively. Avalon was developed primarily as a malt barley cultivar. On the basis of malting evaluations, Avalon has acceptable quality profiles with specific quality traits including high extract, low protein content, and low beta-glucan for the years tested. Avalon provides malt barley producers and end users in the eastern United States with excellent malt quality and a unique and distinct flavor profile having good to moderate resistance to all diseases prevalent in the eastern United States. It is moderately susceptible to Fusarium head blight but has moderately low deoxynivalenol accumulation in the grain.
