“…The changes in net profitability when the N rate was decreased were more pronounced in hybrids than conventional cultivars. This can be explained by the very intense improvement of hybrid cultivars’ grain yield and yield stability in the breeding process (Laidig et al., 2017) that offsets the cost of seeds (Hackauf et al., 2022).…”

Rye (Secale cereale L.) grain production in Kentucky is insufficient to meet the needs of distillers and bakers, in part because there is a knowledge gap about rye management that discourages farmers from choosing this crop. We conducted an economic study to develop recommendations for profitable rye grain production. The aim of this study was to determine the influence of two different nitrogen rates (35 lb N acre−1 and 70 lb N acre−1) on yield and profitability of winter rye grain production. Experiments were conducted in 2020–2021 season at three Kentucky locations: Lexington, Princeton and Adairville. Twenty‐four rye entries were planted in a split plot design experiment and the two nitrogen rates (35 lb N acre−1 and 70 lb N acre−1) were assigned to main plots. There was no significant difference in mean yield between 35 and 70 lb N acre−1. This indicates that less investment in nitrogen fertilizer will not adversely affect grain yield level, will enhance profitability of production, and will benefit distillers due to the higher alcohol yield associated with higher starch and lower protein levels.This article is protected by copyright.

“…the difference in yield between top yielding hybrid and OPVs has grown (Laidig et al, 2017). The process of hybrid rye breeding has been extensively reviewed Hackauf et al, 2022;Miedaner & Laidig, 2019;Wilde & Miedaner, 2021) and is briefly summarized here. Hybrid rye breeding began in 1970 with the discovery of two heterotic pools ("Petkus," "Carsten"), cytoplasmic male sterility (CMS), and nuclear fertility restoration genes (Rf) .…”

“…Instead, increased genomic resources in rye has facilitated genomics‐enabled hybrid rye breeding (Miedaner et al., 2019; Wilde & Miedaner, 2021). Overall, key considerations in hybrid breeding are to improve general combining ability, maintain and improve genetic diversity through incorporating new genetic resources or traits, and understand the relationship between inbred line phenotypes and testcross phenotypes (Geiger & Miedaner, 2009; Hackauf et al., 2022; Wilde & Miedaner, 2021). With over 50 years of development, rye hybrid breeding techniques are the cornerstone of commercial rye breeding.…”

Breeding cereal rye (Secale cereale) for quality traits

et al. 2023

View full text Add to dashboard Cite

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.

“…The breeding of new cultivars aims to increase grain yield and quality by using cultivars with stable yields under variable climatic conditions [5]. A particular direction of progress in breeding cultivars with high yield potential is to obtain hybrid cultivars of rye [6,7]. The heterosis effect occurring in hybrid cultivars allows for higher grain yields resulting from higher ear density [8][9][10].…”

Cultivar, habitat conditions and agrotechnology have an influence on the yield and chemical composition of rye grain. The main anti-nutritional substances present in rye grain include alkylresorcinols, water-soluble pentosans and trypsin inhibitors. The aim of this study was to determine the variability in yield and the concentration of anti-nutritional compounds in the grain of selected winter rye cultivars in relation to nitrogen fertilisation levels and weather conditions. Field studies were conducted at the Experimental Station of IUNG-PIB in Osiny (Poland) in two growing seasons (2018/2019 and 2019/2020). The experiment was located on pseudo-polylic soil using the randomised sub-block method in three replications. The first factor of the experiment was the level of nitrogen fertilisation (0, 70 and 140 kg N∙ha−1) and the second was the population (Dańkowskie Skand, Piastowskie) and hybrid (KWS Vinetto, SU Performer) winter rye cultivars. The study showed that the yield of winter rye depended on the genotype and the level of nitrogen fertilisation. The hybrid cultivars yield ed 17.9% higher in relation to the population cultivars. The content of anti-nutritional compounds in rye grain depended significantly on genotype, level of nitrogen fertilisation and weather conditions. The reason for the higher synthesis of anti-nutrients in rye grain was the stressful weather conditions occurring in the 2019/2020 season. Nitrogen fertilisation influenced the content of alkylresorcinols, water-soluble pentosans and trypsin inhibitor activity in grain. The interaction of cultivar and fertilisation was also found to shape the content of the aforementioned anti-nutrients.
