“…Adams et al (1987) reported that after zoospores carrying the barley yellow mosaic virus (BYMV) colonized roots of immune or virus-resistant barley cultivars, their progeny were unable to transmit the virus again to susceptible hosts. In agreement with these results, other researchers found a lower incidence of BYMV and barley mild mosaic virus (BaMMV) with 3-years of CR and attributed this effect only to the non-host species used (Rubies-Autonell et al 1995). In addition, continuous cultivation of SBWMV-resistant cultivars significantly reduced the incidence of viral infection in a susceptible cultivar after 8 years (Gitton et al 1995).…”

“…Crop rotation (CR) is a common practice in agriculture and contributes to reduce the incidence of plant diseases. Although, CR has been cited in some parts of the world as a strategy to reduce the incidence of P. graminis-transmitted viruses (Chen and Wilson 1995;Rubies-Autonell et al 1995), studies about this practice for virus disease management are poorly explored. In Brazil, the first evidences of CR effect on the reduction of SBWMD incidence and yield losses were obtained from a long-term experiment implanted in 1980 (Reis et al 1985(Reis et al , 1990.…”

Soil-borne wheat mosaic disease (SBWMD) caused by wheat stripe mosaic virus (WhSMV) is one of the most important viral diseases of wheat in Brazil. Farmers have used crop rotation (CR) successfully to reduce the incidence of many diseases in wheat. CR can contribute along with genetic resistance in the management of SBWMD. The objective of this study was to evaluate the effect of CR in SBWMD incidence and wheat yield as compared with wheat monoculture (W). During 2017 and 2018 growth seasons, in a long-term experiment, W and three CR: W1white oats-wheat; W2vetch-white oats-wheat; and W3black oatsbarley-black oats-wheat were evaluated using three wheat cultivars: BRS Parrudo (resistant), BRS Reponte (moderately resistant) and BRS Guamirim (susceptible). The rainiest season (2018) was more favorable to the development of the disease. In this year, CR W2 and W3 significantly decreased SBWMD incidence by 90% compared to wheat monoculture. Also, grain yield (GY) differences between CR were higher in the rainiest season. GY increases up to 58% (BRS Reponte), 81% (BRS Guamirim) and 106% (BRS Parrudo) in W2 and W3. The use of plant species that are non-hosts of WhSMV may be one of the main factors that contribute to the reduction of SBWMD levels.

“…The complex of Barley mild mosaic virus (BaMMV) and Barley yellow mosaic virus (BaYMV) is transmitted by the soil-borne plasmodiophorid Polymyxa graminis and has been a problem for winter grown barley crops in Asia and Europe since the late 1970s and 1980s (Huth and Lesemann 1978;Hill and Evans 1980;Lapierre 1980;Kobayashi et al 1987;Ruan and Jin 1983;Rubies-Autonell et al 1995;Katis et al 1997). To date, 18 resistance loci have been identified against these viruses, with 15 recessive genes and one dominant gene located in H. vulgare (Ordon et al 2005;Kai et al 2012), and two dominant genes (Rym14 Hb and Rym16 Hb ) from H. bulbosum (Ruge et al 2003;Ruge-Wehling et al 2006).…”

Marker assisted separation of resistance genes Rph22 and Rym16 Hb from an associated yield penalty in a barley: Hordeum bulbosum introgression line

et al. 2015

The resistance genes Rph22 and Rym16 (Hb) transferred into barley from Hordeum bulbosum have been separated from a large yield penalty locus that was present in the original introgression line '182Q20'. The Hordeum bulbosum introgression line '182Q20' possesses resistance to barley leaf rust (Rph22) and Barley mild mosaic virus (Rym16 (Hb) ) located on chromosome 2HL. Unfortunately, this line also carries a considerable yield penalty compared with its barley genetic background 'Golden Promise'. Quantitative trait locus (QTL) mapping of the components of yield (total yield, thousand grain weight, hectolitre weight, percentage screenings and screened yield) was performed using 75 recombinant lines derived from the original '182Q20' introgression line. A QTL for the yield penalty was located in the proximal region of the introgressed segment. Marker assisted selection targeting intraspecific recombination events between overlapping H. bulbosum introgression segments was used to develop the lines '372E' and '372H' which feature genetically small introgressions around Rph22. Further yield trials validated the separation of both Rph22 and Rym16 (Hb) from the proximal yield penalty. These results, combined with molecular markers closely linked to Rph22 and Rym16 (Hb) , make these resistance genes more attractive for barley breeding.
