“…Overall, agronomic traits had no prominent correlation with resistance-related traits, except for plant height and qFUSG (−0.45). In the study by Bjørnstad et al 2017 [8], a negative correlation between FHB (visual symptoms) and plant height was detected, and it was speculated that taller plants may escape some of the infection pressure [7,8,44,48], which is common for wheat. In our study, DON content had a slight negative correlation with plant height and a positive correlation with maturity, which would mean that taller and earlier lines are more resistant toward DON accumulation.…”

“…These agronomic traits are not resistance mechanisms as such, but rather give an escape mechanism to infection. Hull-less oats have been reported to have less FHB and to accumulate less DON [9,44,45]. There are implications on other morphological characteristics giving resistance to FHB, including the color of the lemma [44,46,47].…”

“…Hull-less oats have been reported to have less FHB and to accumulate less DON [9,44,45]. There are implications on other morphological characteristics giving resistance to FHB, including the color of the lemma [44,46,47]. In modern oat cultivars, the most studied traits correlated with FHB resistance are plant height, days to heading, days to flowering, days to maturity and anther extrusion.…”

Fusarium head blight (FHB) and the accumulation of deoxynivalenol (DON) mycotoxin induced by Fusarium graminearum and other Fusarium fungi cause serious problems for oat production in the Nordic region (Scandinavia, Fennoscandia). Besides toxin accumulation, FHB causes reduction in grain yield and in germination capacity. Here, genomic approaches for accelerating breeding efforts against FHB and DON accumulation were studied. Resistance-related traits included DON content, F. graminearum DNA (relative to oat DNA) content (qFUSG) measured with real-time quantitative polymerase chain reaction (PCR), Fusarium-infected kernels (FIKs) and germination capacity (GC). Plant germplasm used in the study consisted of mostly breeding lines, and additionally, a few cultivars and exotic accessions. Genome-wide association study (GWAS) and genomic prediction, enabling genomic selection (GS) on the resistance-related and collected agronomic traits, were performed. Considerable genetic correlations between resistance-related traits were observed: DON content had a positive correlation (0.60) with qFUSG and a negative correlation (−0.63) with germination capacity. With the material in hand, we were not able to find any significant associations between markers and resistance-related traits. On the other hand, in genomic prediction, some resistance-related traits showed favorable accuracy in fivefold cross-validation (GC = 0.57). Genomic prediction is a promising method and genomic estimated breeding values (GEBVs) generated for germination capacity are applicable in oat breeding programs.

“…These pigments are formed by oxidation of phenolic compounds to quinones by polyphenol oxidases followed by their polymerization to black high molecular-weight polymers (Nicolas et al, 1994). Melanins accumulating in covering grain tissues reportedly strengthen seed envelopes and protect in this way the developing embryo against mechanical injury, affecting seeds' longevity and germination rate as well as confer an increased resistance on plants under pathogen invasions and unfavorable conditions (Rogers, Kreitner 1983;Duran, Retamal, 1989;Debeaujon et al, 2002;Downie et al, 2003;Loskutov et al, 2016).…”

New varieties of spring oats Otrada and Foma have been created in the Northern Trans-Ural Agricultural Research Institute. Midseason varieties are resistant to drowning and shedding, and mid resistant to spring-and-summer drought, have potential productivity of 7,0-8,0 t/ha. The top grain yield of the variety Otrada was received in 2013 on the Barachatsky state seed-trial ground of the Kemerovo region (7,63 t/ha). The top grain yield of the variety Foma was received in 2014 on the Nerchinsk state seed-trial ground (Trans-Baikal Territory)-8,27 t/ha. Those varieties had rather high grain yield (Kz. = 37,4-38,7). They formed high quality grain (grain-unit up to 518,5-548,0 g/l, thousand-kernel weight is up to 37,4-42,1 g, grain hoodness is 23,6-24,7%). The varieties can be used as forage as well as food. The varieties are listed on the National registry of selection achievements. The variety Otrada has been included in the registry since 2013 and recommended for cultivating forage in 9 regions of Ural, 10 regions of Western Siberia and 12 regions of the Far East of Russia. The variety Foma has been included the registry since 2015 to cultivate for feed and food purposes in 10 regions of Western Siberia, 11 regions of Eastern Siberia and 12 regions of the Far East of Russia.
