“…Rye researchers have used QTL mapping and GWAS for traits including yield, yield components, plant height, disease resistance, abiotic stress tolerance, and quality, and a recent excellent review is available (Hackauf et al., 2021). These studies often employ germplasm with self‐compatibility so that mapping populations can be developed (e.g., RILs, or elite commercial lines).…”

Breeding cereal rye (Secale cereale) for quality traits

Cereal rye (Secale cereale) is a multi‐purpose crop, harvested for grain (for food, feed, and other products) as well as used as a forage or cover crop. The functionality of rye across these spheres is due to its abiotic and biotic stress tolerance and unique phytochemical composition. In this review, we focus on the current state and prospects of breeding rye for quality traits, where we define quality traits as grain, feed, or forage quality. Rye grain for human consumption has numerous healthful compounds, notably high dietary fiber content in grain and unique flavors that contribute to the signature properties of rye baked products and distilled spirits. As a forage, rye is useful in marginal environments and has high quality, including high crude protein, and is thus valuable for livestock production. While yield remains a major focus of breeding efforts, due to recent improvements in rye genomic and phenotypic resources, there are now opportunities for increased attention on breeding high‐quality ryes for multiple end uses. Through genetic improvement of quality traits, cereal rye has the potential to expand and serve multiple markets as a climate‐resilient crop.

“…However, the SI system of rye constrains the development of purebred inbred lines with satisfying seed setting [ 24 ]. This challenge was a long-lasting topic of breeding research in rye and a reasonable number of inbred lines have been developed during the last century [ 25 ]. The ability to set self seed is highly heritable, and self offspring with high self-set were recovered from outbreeding rye populations by the Swedish botanist and geneticist Nils Heribert Nilsson [ 26 ] more than 100 years ago.…”

“…Our steadily growing knowledge of the genetic code of grain size and weight control [ 81 , 82 ] and known major genes governing thousand-grain weight in rye [ 25 , 60 ] offer a chance to develop genome-based precision breeding strategies and to counterbalance the linkage drag effects of non-adapted Rfp genes while simultaneously minimising the costs of restoration in terms of grain yield. Particularly promising for this purpose are genes that cause parent-of-origin effects on F 1 seed size such as MET1 , the primary maintenance DNA methyltransferase in Arabidopsis thaliana.…”

“…The extension of the molecular toolbox available for rye by sophisticated technologies probably is a long-term perspective. In contrast, the proposed International Functional Genomics Project on Rye (IFGPR) for the development of highly replicable rye genetic stocks in the public domain [ 25 ] appears feasible for providing indispensable support in the short term.…”

“…Vavilov Institute of Plant Genetic Resources [ 132 ] and initially described as Estestvennyj Mutant 1 ( EM1 , russ. : natural mutant 1), has been used in breeding of open pollinating cultivars for the genetic improvement of plant height [ 25 ], a quantitative inherited trait with complex genetic architecture in rye [ 60 , 108 , 133 , 134 , 135 ]. However, this approach is hampered by increased frequencies of tall plants, as heterozygous semidwarf genotypes carrying the undesired recessive wild-type allele are difficult to detect within the seed multiplication process of open-pollinating populations [ 136 , 137 , 138 , 139 ].…”

Rye is the only cross-pollinating small-grain cereal. The unique reproduction biology results in an exceptional complexity concerning genetic improvement of rye by breeding. Rye is a close relative of wheat and has a strong adaptation potential that refers to its mating system, making this overlooked cereal readily adjustable to a changing environment. Rye breeding addresses the emerging challenges of food security associated with climate change. The systematic identification, management, and use of its valuable natural diversity became a feasible option in outbreeding rye only following the establishment of hybrid breeding late in the 20th century. In this article, we review the most recent technological advances to improve yield and yield stability in winter rye. Based on recently released reference genome sequences, SMART breeding approaches are described to counterbalance undesired linkage drag effects of major restorer genes on grain yield. We present the development of gibberellin-sensitive semidwarf hybrids as a novel plant breeding innovation based on an approach that is different from current methods of increasing productivity in rye and wheat. Breeding of new rye cultivars with improved performance and resilience is indispensable for a renaissance of this healthy minor cereal as a homogeneous commodity with cultural relevance in Europe that allows for comparatively smooth but substantial complementation of wheat with rye-based diets, supporting the necessary restoration of the balance between human action and nature.

This comprehensive review examined the intricate relationship between climate change and rye (Secale cereale L.) production, focusing on the multifaceted challenges and opportunities posed by changing environmental conditions. Rye is a versatile cereal crop cultivated in temperate regions and is known for its resilience and adaptability to adverse growing conditions. However, as global temperatures and atmospheric CO2 concentrations rise, the effects of climate change on rye growth, yield and grain quality become increasingly apparent. In this review, we summarised the recent research findings on various aspects of rye production and quality under climate change, focusing on factors such as temperature (e.g., increasing temperature) resilience, and viability of rye production in the face of ongoing climate challenges, altered rainfall patterns (changing rainfall distributions with decreasing rainfall in the spring and early summer months as well as heavy rainfall events), biotic stress, agronomic practices and greenhouse gas emissions. Exploring the dynamic interplay among climate change, soil quality, biotic stressors and plant–microbe interactions reveals insights into the response of rye to environmental changes. These interactions shape the complex dynamics that influence the adaptation of rye to evolving environmental conditions. Implications for food security, agricultural sustainability and future research directions are also discussed, highlighting the urgent need for adaptive strategies to ensure the resilience and viability of rye production in the face of ongoing climate challenges.
