Narrative
Barley cultivar Avalon is a moderately early heading, medium height, two-row winter malt barley having very good straw strength. It has high grain yield potential, high-test weight and exceptional malt quality. Juvenile plant growth of Avalon is erect, flag leaves are slightly waxy and upright at the booting stage, leaf sheaths and stems are glabrous and anthocyanin is not present in leaves or stems. The stems have five nodes, closed collars, "straight" peduncles and an exertion of 3 to 10 cm above the base of the flag leaf blade. The two-rowed spikes of Avalon are erect, not dense, strap, and slightly waxy with no overlapping lateral kernels. The rachis is covered with short hairs. Glumes are more than half of Lemma, with short hairs, and their awns are rough and more than equal to length of the glumes. The lemma awn surfaces are rough and awns are longer than the spike length. The basal marking of the lemma is a depression. Rachilla hairs are long. Kernels are covered, mid-long to long with a colorless aleurone with hairs absent on the ventral furrow. Avalon has winter growth habit; it requires vernalization and has sufficient low temperature tolerance for production in the areas tested. Head emergence of Avalon (117 d, Julian) is 3 d later than the cultivar Thoroughbred. In Virginia, the 4 yr (2018-2021) average grain yield of Avalon was 5214 kg ha-1 and its average grain volume weight was 60.8 kg hl-1. In field trials, the reaction of Avalon to diseases (0=no disease to 9=severe infection) evaluated across diverse environments, Avalon has expressed moderate susceptibility to leaf rust, moderate resistance to powdery mildew and net blotch (Pyrenophora teres f. teres Smedeg.). Additionally, in inoculated and mist-irrigated Fusarium Head Blight (FHB) field tests comprised of replicated yield plots, Avalon has expressed moderate susceptibility to FHB and had moderate low deoxynivalenol (DON) accumulation.

Pedigree
Description:
'Avalon', formerly tested as VA16M-81 (2R), winter malt barley was derived from the cross 'Thoroughbred' (PI 634933) / 2107-2627. Parentage of Thoroughbred is VA90-44-110 / 'Plaisant' (PI584894), a French malting barley. Ancestry of 2107-2627 is Z057N036N // 'Adonis' / 'Merit'. The barley line 2107-2627 is a two-rowed malt barley line developed by Busch Agricultural Resources Inc. (BARI) that was obtained and tested through the USDA-ARS-NIFA Barley Coordinated Agriculture Project (CAP).
