“…At a more conservative threshold for marker significance, a threshold of p \ 1.168 9 10 -4 for significance, 42 significant marker associations involving 25 SNP markers on 5 chromosomes (1A, 1D, 2B, 2D, and 4B) and three unmapped SNPs were identified in the two years. Previous QTL studies have identified between 32 and 380 QTLs for NUE traits (Cormier et al 2016).…”

Variation for nitrogen use efficiency traits in current and historical great plains hard winter wheat

Wheat genotypes that efficiently capture and convert available soil nitrogen into harvested grain protein are key to sustainably meeting the rising global demand for grain protein. The 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 identify quantitative trait loci associated with NUE traits in this germplasm. NUE traits were measured in a panel of 299 hard winter wheat genotypes, representing historically important and contemporary germplasm, from across the growing region. Trials were grown in two years at two levels of nitrogen fertility. Genotype and genotype 9 year interaction effects were highly significant for NUE traits, while genotype 9 nitrogen rate interactions were non-significant. Strong genetic correlations of plant height and flowering date with NUE traits were observed. Wheat breeders have improved NUE: the subset of 183 genotypes that were released as cultivars after 1960 demonstrated significant trends with year of release for improved grain N yield, grain yield, nitrogen harvest index, nitrogen uptake efficiency, nitrogen utilization efficiency, and post-anthesis nitrogen uptake. In genome-wide association analyses, plant height and flowering date were important covariates in the mixed models, and plant height and flowering date substantially explained the variation in NUE traits in this germplasm. Marker-trait associations were identified that may prove useful in breeding.

“…Association mapping (Bordes et al 2013;Cormier et al 2014) approaches also have been applied to NUE traits. These QTL analyses were recently reviewed by Cormier et al (2016) and consistently indicate a large number (32-380) of small-effect QTLs for NUE traits. Similar studies have not been reported in North American winter wheat germplasm.…”

“…Fertilisation clearly gradually enhanced soil fertility by increasing soil quality, and this was supported by the research results from Christensen (1997), Johnston (1997) and Edmeades (2003). During the experimental period, the fertiliser effect was combined with the introduction of new more productive wheat cultivars with better nutrient use efficiency and/or better structure and higher component yield capacity (Mladenov et al 2011, Sanchez-Garcia et al 2012, Cormier et al 2016. This resulted in an increasing difference between non-fertilised controls and the most productive treatments.…”

Gradual changes in soil productivity can only be measured by long-term monitoring or field experiments. Long-term agro-ecosystem experiments help evaluation of the cropping system effects on soil quality, sustainability of these systems and provide early warning indication of threats to future crop production (Richter et al. 2007). Fertilisation is one of the most important intensification factors significantly effecting crop yield and quality (Černý et al. 2010). Edmeades (2003) contended that nutrient inputs can increase crop production by 300-400% and are essential in maintaining long-term sustainability. A long-term Broadbalk wheat experiment confirmed a strong yield response to nitrogen fertilisation with the curvilinear character of nitrogen (N) response curve (Brentrup et al. 2004). Jaakkola and YliHalla (2008) reported a significant decrease in cereal yields after 30 years with N fertilisation not balanced with phosphorus (P) and potassium (K) fertilisers. Moreover, yield and its response to fertilisers depend on preceding crops, and the results from a Hungarian long-term experiment (Berzsenyi et al. 2000) showed that yields of wheat cropped in monoculture were always lower than in crop rotation. Simultaneously, significantly higher yields were obtained at high NPK fertilisation rates, especially in rotations with a high proportion of cereals. The combined application of organic manure and inorganic fertiliser was an The influence of mineral fertilisers, liming, farmyard manure and sowing rate on the winter wheat grain yields was studied in a long-term field experiment at 4 sites under different soil and climatic conditions in the Czech Republic. A total of 135 partial fraction-factorial experiments were performed between 1980 and 2013 and evaluated using a statistical model with linear and quadratic terms for each factor. Yield trends demonstrated remarkable influence of fertilisation at two sites of lower starting productivity. Here, grain yields increased by 50% and 25% since the trial commencement, while the rate of yield increase was low at more productive sites. Yields were the most frequently influenced by nitrogen (N) fertilisation, uniformly at all sites. N response curves were strongly curvilinear, but these differed between sites and were affected by preceding crops. The relative frequency of statistically significant influences decreased in the following order: N (significant at α < 0.05 in 89% of all partial trials) > sowing rate (29%) > phosphorus (22%) > farmyard manure (15%) > potassium (12%) > liming (8%). This order and the frequencies of these influences are discussed with regard to relevant site and soil conditions.

Durum wheat (Triticum turgidum L. subsp. durum) is the most cultivated cereal crop in the Mediterranean basin, traditionally grown under rainfed conditions using conventional tillage. Agronomical practices, soil type and climate variables are known to influence crop productivity. Their interaction effect is very complex and the time in which they occur strongly affects yield and quality. The nitrogen supply, in combination with climatic conditions, is the main constraint determining the physiological performance, grain yield and quality response of wheat. In addition, the N formulation, fertilizer management, crop sequence, seasonal trends, and the supply of residual and mineralized N influence the response of wheat to N fertilizer. N fertilizer management must be optimized to prevent N deficiency in the critical crop growth period, to avoid yield and quality losses and also prevent the excessive application of N fertilizer, thus reducing the environmental impact. The split application of N fertilizer is a promising strategy that satisfies plant needs and reduces N losses through improved nitrogen use efficiency (NUE). Such a strategy can result in a remarkable reduction in greenhouse gas (GHG) emissions and the carbon footprint of Italian durum wheat, considering that the highest proportion of the total emissions deriving from N fertilizer production and its application.
