Effect of Awn Suppression on Grain Yield and Agronomic Traits in Hard Red Winter Wheat

Fowler, D. B. 2012. Moats hard red winter wheat. Can. J. Plant Sci. 92: 191–193. Moats is a hard red winter wheat (Triticum aestivum L.) that is eligible for grades of the Canada Western Red Winter (CWRW) wheat class. It has excellent stem and leaf rust resistance and higher grain yield and protein concentration than the Central Winter Wheat Cooperative Registration Trial CWRW grain quality check cultivar, CDC Buteo. Its grain yield is similar to the high-yielding Registration Trial check cultivar, CDC Falcon, and lower than Accipiter, which is a more recent high-yielding winter wheat cultivar released in the Canada Western General Purpose wheat class. A suitable combination of grain quality, rust resistance and yield make Moats widely adapted in the winter wheat production area of western Canada.

Several previous studies have reported that grain yield of cereal crops was greater from multiple than from single nitrogen (N) applications. The purpose of the study was to determine the influence of the time and rate of N application on the yield and quality of hard red winter wheat grown in Ontario. One experiment was conducted in each of 2 yr using a factorial arrangement of treatments. Factors were rate of N application (40, 80, 120, 160, 200 or 240 kg N ha−1), and timing of N application (100/0/0, 75/25/0, 50/50/0 or 25/50/25 percent of the N applied at Zadok’s growth stages 22/32/45). Early N application reduced grain yield in a year of below-average precipitation, increased grain yield in a year of average precipitation, and increased straw yield in both years. Late N application increased grain crude protein concentration and harvest index in both years. Given the lack of a consistent yield increase and the added cost of application, it is unlikely that multiple N applications will be economical for hard red winter wheat production in Ontario.Key words: Triticum aestivum, intensive cereal management, yield components, wheat

Red Winter Wheat

Wheat streak mosaic virus (WSMV) causes significant yield loss in hard red winter wheat in the U.S. Southern High Plains. Despite the prevalence of this pathogen, little is known about the physiological response of wheat to WSMV infection. A 2-year study was initiated to (i) investigate the effect of WSMV, inoculated at different development stages, on shoot and root growth, water use, water use efficiency (WUE), and photosynthesis and (ii) understand the relationships between yield and photosynthetic parameters during WSMV infection. Two greenhouse experiments were conducted with two wheat cultivars mechanically inoculated with WSMV at different developmental stages, from three-leaf to booting. WSMV inoculated early, at three- to five-leaf stage, resulted in a significant reduction in shoot biomass, root dry weight, and yield compared with wheat infected at the jointing and booting stages. However, even when inoculated as late as jointing, WSMV still reduced grain yield by at least 53%. Reduced tillers, shoot biomass, root dry weight, water use, and WUE contributed to yield loss under WSMV infection. However, infection by WSMV did not affect rooting depth and the number of seminal roots but reduced the number of nodal roots. Leaf photosynthetic parameters (chlorophyll [SPAD], net photosynthetic rate [Pn], stomatal conductance [Gs], intercellular CO2 concentration [Ci], and transpiration rate [Tr]) were reduced when infected by WSMV, and early infection reduced parameters more than late infection. Photosynthetic parameters had a linear relationship with grain yield and shoot biomass. The reduced Pn under WSMV infection was mainly in response to decreased Gs, Ci, and SPAD. The results of this study indicated that leaf chlorophyll and gas exchange parameters can be used to quantify WSMV effects on biomass and grain yield in wheat.

Fowler, D. B. 2011. Accipiter hard red winter wheat. Can. J. Plant Sci. 91: 363–365. Accipiter is an intermediate height, high-yielding, winter wheat (Triticum aestivum L.) cultivar with good stem and moderate leaf rust resistance that is registered for production in western Canada. It is a hard red winter wheat cultivar that is eligible for grades of the Canada Western General Purpose (CWGP) wheat class. The CWGP class was created in 2007 to encourage the development of cultivars to fill the high energy demands of the biofuel and livestock feed markets in western Canada. The grain yield of Accipiter was 114% of the Canada Western Red Winter Wheat class grain quality check cultivar, CDC Osprey, and 103% of the high-yielding check, CDC Falcon. High grain yield potential combined with good agronomic and disease packages make Accipiter a good fit for the CWGP class.

Peregrine is a medium tall, high-yielding, stem and leaf rust resistant winter wheat (Triticum aestivum L.) that is registered for production in western Canada. It is a hard red winter wheat cultivar that is eligible for grades of the Canada Western General Purpose (CWGP) wheat class. The CWGP class was created in 2007 to encourage the development of cultivars to fill the high energy demands of the biofuel and livestock feed markets in western Canada. In Manitoba and Saskatchewan, the grain yield of Peregrine was 117% of the Canada Western Red Winter Wheat Class grain quality check cultivar, CDC Osprey, and 106% of the high-yielding check, CDC Falcon. High grain yield potential and a high level of rust resistance mean that Peregrine provides a good fit for the CWGP class.

Red Winter Wheat

A two-year study (harvest years 2019 and 2020) was conducted to investigate the effect of a commercially available biofertilizer, in combination with variable nitrogen (N) rate, on bread baking quality and agronomic traits in hard winter wheat grown in conventional (CONV) and organic (ORG) farming systems in Kentucky, USA. The hard red winter wheat cultivar ‘Vision 45’ was used with three N rates (44, 89.6 and 134.5 kg/ha as Low, Med and High, respectively) and three biofertilizer spray regimes (no spray, one spray and two sprays). All traits measured were significantly affected by the agricultural production system (CONV or ORG) and N rate, although trends in their interactions were inconsistent between years. In Y2, yield was greatest in treatments with high N rates and in the ORG system. Biofertilizer treatments had a negative to neutral effect on grain yield. Baking quality traits such as protein content, lactic acid solvent retention capacity and sedimentation value (SV) were consistently greater in the CONV system and increased with the higher N application rates. Similarly, biofertilizer application had no effect on predictive baking quality traits, except for SV in year 1 of the study, where it increased with two sprays. Loaf volume was consistently greater from wheat grown in CONV treatments. From these results, we conclude that further research is warranted to evaluate the potential for biofertilizers to enhance N uptake and affect bread baking quality or other end-use traits. Additional research may be especially useful in organic production systems where biologically based N fertilizers are utilized, and treatments were not negatively affected by biofertilizer applications. Such strategies may be needed to increase protein quantity and gluten quality to optimize winter wheat production for bread baking qualities in the southeastern USA.
