Registration of ‘Avery’ Hard Red Winter Wheat

Abstract

Avery' (Reg. No. CV-1143, PI 676977) hard red winter wheat (Triticum aestivum L.) was developed by the Colorado Agricultural Experiment Station and released in August 2015 through a marketing agreement with the Colorado Wheat Research Foundation. In addition to researchers at Colorado State University, USDA-ARS researchers at Manhattan, KS, St. Paul, MN, and Pullman, WA, contributed to its development. Avery was developed with the objective of making available a hard red winter wheat cultivar with improved grain yield and end-use quality compared with 'Byrd' hard red winter wheat. Avery is a doubled haploid cultivar developed using the wheat x maize (Zea mays L.) wide hybridization method from the cross 'TAM 112'/Byrd made in 2009 at Fort Collins, CO. Following doubled haploid generation in 2010, Avery was selected at Fort Collins in July 2011, assigned experimental line number CO11D174, and evaluated in yield trials in Colorado and other states in the US hard winter wheat region from 2012 to 2015. The name Avery was chosen in honor of early Colorado business and agricultural pioneer Franklin C. Avery (1849-1923). Hard Winter Wheat Quality Laboratory, 1515 College Ave., Manhattan, KS 66502.

Registration of ‘KS Western Star’ hard red winter wheat

“…The Fisher protected LSD test (α = .05) was used to compare the least square means for genotypic effects. Due to the large error heterogeneity among several environments, grain yield data were analyzed with a two‐stage procedure (Haley et al., 2018). In brief, best linear unbiased estimates (BLUEs) were obtained for each environment in the first stage.…”

“…Data from western and central/eastern Kansas locations were analyzed separately. Due to the large error heterogeneity (>10 times difference) for grain yield data among several environments, grain yield data were analyzed using a two‐stage procedure (Haley et al., 2018). In brief, best linear unbiased estimates (BLUEs) were obtained for each individual environment in the first stage, and then BLUEs of common entries were subjected to a combined analysis across year‐locations using a heterogeneous compound symmetry model (Malosetti, Ribaut, & van Eeuwijk, 2013) that can efficiently accommodate the heterogeneity or error variances among environments.…”

Registration of ‘KS Dallas’ hard red winter wheat

“…Data from western and central/eastern Kansas locations were analyzed separately, and only the results from western Kansas were reported. Due to the large error heterogeneity (>10 times difference) for grain yield data among several environments, grain yield data were analyzed using a two‐stage procedure (Haley et al., 2018). In brief, best linear unbiased estimates (BLUEs) were obtained for each individual environment in the first stage, and then BLUEs of common entries were subjected to a combined analysis across year‐locations using a heterogeneous compound symmetry model (Malosetti, Ribaut, & van Eeuwijk, 2013) that can efficiently accommodate the heterogeneity of error variances among environments.…”
