Registration of ‘Atlantic’ Winter Barley

Abstract

‘Atlantic’ (Reg. No. CV‐354, PI 665041), a six‐row, hulled winter barley (Hordeum vulgare L.) tested as VA06B‐19 by the Virginia Agricultural Experiment Station, was released in March 2011. Atlantic was derived from the cross VA97B‐176/VA92‐44‐279 using a modified bulk‐breeding method. It was evaluated in the Virginia Official Variety Trials from 2008 to 2013 in replicated tests at five to six locations. Atlantic's average grain yield (5349 kg ha−1) was higher than the check cultivars Wysor, Callao, and Price and similar to Thoroughbred. Average grain volume weight of Atlantic (60.8 kg hL−1) was similar to the check cultivar Price and higher than Thoroughbred, Callao, and Wysor. Head emergence of Atlantic is 7 d earlier than Thoroughbred (the predominant barley cultivar grown in Virginia and the eastern United States) and similar to that of Callao. Earlier maturity is a primary factor determining whether barley or wheat (Triticum aestivum L.) is used in double‐cropping systems with soybean [Glycine max (L.) Merr.]. Grain of Atlantic had an average starch concentration (56.5%) that was higher than Callao, similar to Price, but lower than Thoroughbred. Atlantic provides barley producers and end users in the eastern United States with a widely adapted, early‐maturing winter barley cultivar that has good grain quality and is highly resistant to powdery mildew [caused by Blumeria graminis (DC.) E.O. Speer f. sp. hordei Em. Marchal] based on its performance in state and uniform winter barley yield trials.

Registration of ‘SB255’ winter barley

“…SB255 winter barley will provide producers in the eastern United States with a high‐yielding, high grain volume weight cultivar having moderate resistant to FHB, leaf rust, and powdery mildew. It has expressed higher levels of resistance to leaf rust than the cultivars ‘Atlantic’ (PI 665041; Brooks et al., 2014), ‘Price’ (PI 632708; Brooks et al., 2005a), and ‘Callao’ (PI 592800; Price et al., 1996) and is more resistant than ‘Thoroughbred’ (PI 634933; Brooks et al., 2005b) to powdery mildew and leaf rust. In addition, FHB values for SB255 are similar to the moderately resistant six‐rowed cultivars ‘Nomini’ and ‘Secretariat’ (PI 673931; Brooks et al., 2016) and lower than the check cultivars Atlantic, Thoroughbred, Callao, and Price.…”

Registration of ‘Secretariat’ Winter Barley

“…Marchal]. Secretariat has expressed higher levels of resistance to leaf rust than the cultivars ‘Atlantic’ (PI 665041; Brooks et al, 2014), ‘Price’ (PI 632708; Brooks et al, 2005a), and ‘Callao’ (PI 592800; Price et al, 1996) and is more resistant than ‘Thoroughbred’ (PI 634933; Brooks et al, 2005b) to powdery mildew and leaf rust. In addition to good kernel physical characteristics, Secretariat has a mean starch concentration (56.9%) similar to Price and Callao and a protein concentration (9.8%) similar to Atlantic, Thoroughbred, Price, and Callao.…”
