“…Considerable ageing trends for yield and diseases have been reported, e.g. by Mackay et al ( 2011 ) and Laidig et al ( 2021 ) in WW variety trials. Both studies assumed that in the treated intensity no ageing effect was present, which means that genetic and non-genetic trends in I2 and I1 were identical.…”

“…In this regard, one needs to note that there is a major difference in assessing the breeding progress of diseases from trials with historic varieties (also called ‘vintage trials’) and breeding progress based on historic data. In general, results from trials with historic varieties showed a stronger improvement of disease resistance compared to the progress assessed by historic data (Laidig et al 2021 ). This difference can be ascribed to the dynamic virulence of biotrophic pathogen populations.…”

“…While most of the studies evaluated yield loss due to diseases, we found only few studies evaluating the breeding progress for disease resistance and lodging. Most of them focused on winter wheat (Ahlemeyer and Friedt 2011;Leisova-Svobodova et al 2020;Voss-Fels et al 2019;Zetsche et al 2020;Zhang et al 2020), a few on barley (e.g. Grausgruber et al 2002;Ahlemeyer et al 2008), one on triticale (Losert et al 2017) but none on rye.…”

“…Despite intensive crop protection measures and progress in resistance breeding, considerable yield losses for cereals due to diseases and lodging are reported by numerous studies (e.g. Jaysena et al 2007 ; Wiik 2009 ; Jahn et al 2012 ; Fones and Gurr 2015 ; Jevtic et al 2017 ; Laidig et al 2021 ; Willocquet et al 2021 ). Oerke and Dehne ( 2004 ) reported yield losses due to pathogens of 10% in wheat and 14% in barley in Northwest Europe.…”

“…Only few studies on breeding progress built on historic variety trial time series data (e.g. Mackay et al 2011 ; Laidig et al 2021 ). Most studies were conducted using historic varieties released over a period of several decades and growing them over 2 to 3 years under natural infection (e.g.…”

Long-term breeding progress of yield, yield-related, and disease resistance traits in five cereal crops of German variety trials

et al. 2021

Key message Considerable breeding progress in cereal and disease resistances, but not in stem stability was found. Ageing effects decreased yield and increased disease susceptibility indicating that new varieties are constantly needed. Abstract Plant breeding and improved crop management generated considerable progress in cereal performance over the last decades. Climate change, as well as the political and social demand for more environmentally friendly production, require ongoing breeding progress. This study quantified long-term trends for breeding progress and ageing effects of yield, yield-related traits, and disease resistance traits from German variety trials for five cereal crops with a broad spectrum of genotypes. The varieties were grown over a wide range of environmental conditions during 1988–2019 under two intensity levels, without (I1) and with (I2) fungicides and growth regulators. Breeding progress regarding yield increase was the highest in winter barley followed by winter rye hybrid and the lowest in winter rye population varieties. Yield gaps between I2 and I1 widened for barleys, while they shrank for the other crops. A notable decrease in stem stability became apparent in I1 in most crops, while for diseases generally a decrasing susceptibility was found, especially for mildew, brown rust, scald, and dwarf leaf rust. The reduction in disease susceptibility in I2 (treated) was considerably higher than in I1. Our results revealed that yield performance and disease resistance of varieties were subject to considerable ageing effects, reducing yield and increasing disease susceptibility. Nevertheless, we quantified notable achievements in breeding progress for most disease resistances. This study indicated an urgent and continues need for new improved varieties, not only to combat ageing effects and generate higher yield potential, but also to offset future reduction in plant protection intensity.

Evaluating the effect of nitrogen fertilizer rate and source on the performance of open‐pollinated rye (Secale cereale L.) cultivars in contrasting European environments

Rye (Secale cereale L.) is a minor cereal with potential to support sustainable farming practices. This study evaluated the performance of four old and modern European open‐pollinated winter rye cultivars grown with different nitrogen (N) sources (cattle slurry, farmyard manure, biogas digestate, mineral N) at two rates of N 50 and 100 kg ha−1 in the United Kingdom and Estonia, in the 2014–2015 and 2015–2016 growing seasons. Grain yield in Estonia was higher than the United Kingdom (6.2 vs. 4.8 t ha−1), which was attributed to a higher ear density (409.4 vs. 249.7 ears m−2) and grain number per ear (50.2 vs. 43.2), although 1,000‐grain weight was higher in the United Kingdom. There were clear differences between sites in the response to N source with significant N source × year interactions. Biogas digestate and mineral N produced higher grain yield than farmyard manure and cattle slurry in the United Kingdom, whereas in Estonia cattle slurry had a lower grain yield than the other N sources. Foliar diseases were absent in Estonia and in the United Kingdom, and N source only affected powdery mildew and leaf blotch on Leaf 2. The response of grain quality to N source and variety was consistent across both sites. The modern variety Elias had the highest Hagberg falling number and specific weight but the lowest protein content, whereas the variety Schlägler had the highest protein content but lowest specific weight. The benefits of selecting cultivars for specific environments are shown by the interactions between genotype and environment.

Background Developing and enriching genetic resources plays important role in the crop improvement. The flag leaf affects plant architecture and contributes to the grain yield of wheat (Triticum aestivum L.). The genetic improvement of flag leaf traits faces problems such as a limited genetic basis. Among the various genetic resources of wheat, Thinopyrum intermedium has been utilized as a valuable resource in genetic improvement due to its disease resistance, large spikes, large leaves, and multiple flowers. In this study, a recombinant inbred line (RIL) population was derived from common wheat Yannong15 and wheat-Th. intermedium introgression line SN304 was used to identify the quantitative trait loci (QTL) for flag leaf-related traits. Results QTL mapping was performed for flag leaf length (FLL), flag leaf width (FLW) and flag leaf area (FLA). A total of 77 QTLs were detected, and among these, 51 QTLs with positive alleles were contributed by SN304. Fourteen major QTLs for flag leaf traits were detected on chromosomes 2B, 3B, 4B, and 2D. Additionally, 28 QTLs and 8 QTLs for flag leaf-related traits were detected in low-phosphorus and drought environments, respectively. Based on major QTLs of positive alleles from SN304, we identified a pair of double-ended anchor primers mapped on chromosome 2B and amplified a specific band of Th. intermedium in SN304. Moreover, there was a major colocated QTL on chromosome 2B, called QFll/Flw/Fla-2B, which was delimited to a physical interval of approximately 2.9 Mb and contained 20 candidate genes. Through gene sequence and expression analysis, four candidate genes associated with flag leaf formation and growth in the QTL interval were identified. Conclusion These results promote the fine mapping of QFll/Flw/Fla-2B, which have pleiotropic effects, and will facilitate the identification of candidate genes for flag leaf-related traits. Additionally, this work provides a theoretical basis for the application of Th. intermedium in wheat breeding.
