“…Tight linkage of markers representing different patterns of segregation distortion found on chromosome 3RS (pr1049 and pm6/198) suggests that individual QTL may comprise more than one PHS gene. Chromosome regions found in this study by means of BSG coincided with QTLs for PHS and /or alphaamylase activity detected within the 541 9 Ot1-3 or DS2 9 RXL10 mapping populations (Masojć and Milczarski 2009). For instance, two separate groups of markers detected in distal part of chromosome 6RL corresponded to QTLs for alpha-amylase activity.…”

“…It showed that frequencies of markers from chromosome regions corresponding to previously detected QTLs for PHS and alpha-amylase activity (Masojć and Milczarski 2009) are strongly affected by disruptive selection for extreme PHS phenotypes.…”

“…This important conclusion could not be formulated on the basis of QTL analysis performed earlier (Masojć and Milczarski 2009). PHSE loci, although not involved in control of sprouting resistance, might be interesting for breeders selecting genotypes capable to germinate rapidly after harvest as it is preferred in case of malting barley.…”

“…3.0 software package (Lincoln et al 1993) was used for the map construction. One SCAR (Scsz732) and two STS markers (psr106 and psr454) mapped earlier in the vicinity of QTLs for PHS (Masojć and Milczarski 2009) were included into BSG analysis.…”

“…Preharvest sprouting of rye Masojć and Milczarski 2009) and other cereal species Gale et al 2002) is controlled by a complex system of QTLs distributed on all chromosomes. This system coincides in great part with QTLs affecting alpha-amylase activity in sound grain Milczarski 2005, 2009).…”

Three classes of loci controlling preharvest sprouting in rye (Secale cereale L.) discerned by means of bidirectional selective genotyping (BSG)

Bidirectional selective genotyping (BSG) carried out on recombinant inbred lines (RILs) derived from the 541 9 Ot1-3 intercross revealed three classes of selection responsive loci underlying preharvest sprouting (PHS) in rye. Ten PHS directional loci (PHSD) located on chromosomes 1RL (3), 3RS(2), 3RL (2), 5RL (2), and 7RS (1) responded significantly to both directions of the disruptive selection and were epistatic to the remaining two classes. Nine PHS resistance loci (PHSR) mapped on chromosomes 1RS, 1RL, 2RS, 3RS, 4RS, 5RS, 5RL, and 6RL (2) responded only to selection for sprouting resistance, being neutral for selection carried out in opposite direction. Eight PHS enhancing loci mapped on chromosomes 2RL, 3RL, 4RL, 5RL, 6RS, and 7RS (3) were affected by selection for sprouting susceptibility and did not respond to selection for sprouting resistance. Map positions of the selection responsive loci coincided with QTLs for PHS and alpha-amylase activity (AA) detected earlier, but BSG coupled with molecular mapping increased precision of PHS dissection in rye. Efficient strategy of marker assisted selection for preharvest sprouting resistance in rye should be based on PHSD and PHSR loci.

Breeding cereal rye (Secale cereale) for quality traits

et al. 2023

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.
