“…In the current study, 101 kg N ha −1 applied at Zadoks GS 30 also resulted in the highest grain N contents in all environments under the standard spring N rates. These effects are in agreement with previous studies of hard red winter wheat in Nebraska (Bhatta et al, 2017) and Virginia (Thomason et al, 2007), which reported improved end-use qualities with higher N application rates later in plant development. However, higher grain N, in the form of increased protein content, either has a negative or neutral effect on end-use quality in soft red winter wheat, which is largely dependent on protein quality and environment.…”

Optimal N application is critical to ensure profitable soft red winter wheat (Triticum aestivum L.) production and limit negative environmental effects. This study was conducted using 12 wheat lines grown in two Ohio and six Virginia environments to determine the effects of differentially split N rates on grain yield, yield components, and N‐related traits. Upon analysis of wheat lines in two contrasting photoperiod groups, it was discovered that wheat lines containing the photoperiod sensitivity allele (Ppd‐D1b) conferred a significant (P < 0.05) yield advantage under N‐limited conditions in Ohio and across N treatments in half of the Virginia testing environments. This resulted from increased harvest index, grains per square meter, number of kernels per spike, and floret fertility in Ppd‐D1b lines relative to lines with the insensitive allele (Ppd‐D1a). However, wheat genotypes in the photoperiod‐insensitive allelic group had significantly higher (P < 0.05) grain N concentration in all Virginia testing sites. A spring split N application of 33 kg N ha−1 at Zadoks growth stage (GS) 25 and 101 kg N ha−1 at Zadoks GS 30 produced the highest grain yields and grain N contents in five of the six Virginia environments. Nitrogen utilization efficiency was the primary contributor to variation in N use efficiency under higher N rates, whereas N uptake efficiency was the greatest contributor under low N rates. The contribution of N utilization and uptake efficiencies varied among wheat lines in the Ppd‐D1a group when 67 kg N ha−1 was applied at Zadoks GS 25 under the moderate and standard N rates.

‘Vision 45’ (Reg. No. CV‐1110, PI 667642), is a hard red winter (HRW) wheat (Triticum aestivum L.) cultivar that was developed and tested as VA07HRW‐45 and released by the Virginia Agricultural Experiment Station in 2012. Vision 45 was derived from the cross ‘Provinciale’/‘Vision 10’ using a modified bulk breeding method. It was tested in replicated yield trials in Virginia (2008–2014) and in the USDA‐ARS Uniform Bread Wheat (UBW) Trials (2009–2014). Vision 45 is a widely adapted, high‐yielding, awned, semidwarf (unknown Rht gene) HRW wheat with mid‐ to late‐season spike emergence, strong straw strength, and resistance or moderate resistance to diseases prevalent in the mid‐Atlantic region. In Virginia, Vision 45 was the highest‐yielding hard winter wheat over a 4‐yr period, having an average grain yield (5499 kg ha−1) that was slightly higher than the soft red winter wheat cultivar Tribute (PI 654422), which was 5181 kg ha−1. Over 6 yr and 97 environments in the UBW Trials, Vision 45 had an average grain yield of 4924 kg ha−1, one of the highest‐yielding hard wheat cultivars. Vision 45 has good end‐use quality on the basis of comparisons with the HRW wheat check cultivar Jagger (PI 593688), for flour yield (70.7 versus 70.3 g 100 g−1), flour protein (10.5 versus 10.6 g 100 g−1), flour water absorption (60.7 vs. 61.3 g 100 g−1), dough mixing tolerance (2.7 versus 2.7), pup‐loaf volume (798 versus 773 cm3), and crumb grain scores (3.3 versus 2.8).

The objective of this research was to develop widely adapted hard winter wheat (Triticum aestivum L.) varieties to meet the needs of mills, bakeries, and consumers in the eastern and Great Plains regions of the United States. ‘LCS Wizard’ (Reg. No. CV‐1111, PI 669574), a hard red winter (HRW) wheat, was developed and tested as VA08HRW‐80 and co‐released by the Virginia Agricultural Experiment Station and Limagrain Cereal Seeds, LLC in 2013. LCS Wizard was derived from the three‐way cross S.6742/92PAN1#33//92PIN#107 using a modified bulk breeding method. LCS Wizard is a widely adapted, high‐yielding, awned, semidwarf (Rht1) HRW wheat with midseason spike emergence and resistance or moderate resistance to diseases prevalent in the mid‐Atlantic and Great Plains regions. In the 2014 Uniform Bread Wheat Trial conducted over 17 locations in eastern states, LCS Wizard produced an average grain yield of 4717 kg ha−1, similar to ‘Vision 45’ (4650 kg ha−1). In the northern Great Plains, the average grain yield over 54 locations in 2012 of LCS Wizard (4419 kg ha−1) was slightly lower than that of ‘Overland’ (4659 kg ha−1). In the southern Great Plains, its average grain yield (3844 kg ha−1) over 85 locations was slightly higher than that of Fuller (3757 kg ha−1). LCS Wizard has acceptable end‐use quality in both the eastern and Great Plains regions of the United States.
