Grain protein deviation
WebThe purposes of this study were: to characterize the genetic variation for nitrogen use efficiency (NUE) traits within hard winter wheat adapted to the Great Plains of the United States and evaluate trends in the germplasm with year of release; to explore relationships among traits that may be used for selection within breeding programs; and to … WebMar 15, 2024 · Nitrogen Harvest Index (NHI) was defined as the ratio of N harvested as grain (GY × GNC) to NTA. Grain protein deviation (GPD) was the residual from the linear regression of GPC on GY in each trial. Within each trial, the total N available to the crop was determined empirically as the 95th percentile of NTA (NTA max) as per Cormier et al. ( …

WebMar 24, 2024 · Grain protein concentration (GPC) is an important trait in durum cultivar development as a major determinant of the nutritional value of grain and end-use product quality. However, it is challenging to simultaneously select both GPC and grain yield (GY) due to the negative correlation between them. WebSep 13, 2024 · This average increase of 7.7% in thousand kernel weight translated to a positive mid-parent heterosis for grain yield for 86% of hybrids. In addition, hybrids displayed a positive grain protein deviation leading to a +4.7% heterosis in protein yield.
