Abstract:
Barley yellow dwarf (BYD) is one of the major viral diseases of cereals. Phenotyping BYD in wheat is extremely challenging due to similarities to other biotic and abiotic stresses. Breeding for resistance is additionally challenging as the wheat primary germplasm pool lacks genetic resistance, with most of the few resistance genes named to date originating from a wild relative species. The objectives of this study were to, i) evaluate the use of high-throughput phenotyping (HTP) from unmanned aerial systems to improve BYD assessment and selection, ii) identify genomic regions associated with BYD resistance, and iii) evaluate genomic prediction models ability to predict BYD resistance. Up to 107 wheat lines were phenotyped during each of five field seasons under both insecticide treated and untreated plots. Across all seasons, BYD severity was lower with the insecticide treatment and plant height (PTHTM) and grain yield (GY) showed increased values relative to untreated entries. Only 9.2% of the lines were positive for the presence of the translocated segment carrying resistance gene Bdv2 on chromosome 7DL. Despite the low frequency, this region was identified through association mapping. Furthermore, we mapped a potentially novel genomic region for resistance on chromosome 5AS. Given the variable heritability of the trait (0.211 ? 0.806), we obtained relatively good predictive ability for BYD severity ranging between 0.06 ? 0.26. Including Bdv2 on the predictive model had a large effect for predicting BYD but almost no effect for PTHTM and GY. This study was the first attempt to characterize BYD using field-HTP and apply GS to predict the disease severity. These methods have the potential to improve BYD characterization and identifying new sources of resistance will be crucial for delivering BYD resistant germplasm. MenosAbstract:

Dentro del género Eucalyptus (constituido por más de 550 especies) existe un grupo de especies cuya madera posee duramen de coloración rojiza, por lo cual se los denomina comúnmente como eucaliptos colorados. Estos eucaliptos han sido plantados prácticamente en todo el territorio nacional, inicialmente con fines protectores (como montes de abrigo y sombra para el ganado) y posteriormente con fines productivos, para leña y para diversos usos en los propios establecimientos (piques, postes, etc). Sin embargo, el desarrollo de la forestación con fines industriales, ocurrido en los últimos 15 años, llevó a
que los eucaliptos colorados fuesen sustituidos por especies de más rápido crecimiento y/o de maderas de gran demanda en el mercado internacional. Esto ha conducido a que hoy en día la forestación en Uruguay, con un área aproximada de 700 mil hectáreas, se concentre fuertemente en tres especies: Eucalyptus globulus (270 mil hectáreas), Eucalyptus grandis (160 mil hectáreas) y Pinus taeda (130 mil hectáreas). Por tal motivo, tanto la Dirección General Forestal como el sector forestal e industrial de la madera han reconocido la necesidad de diversificar la oferta de productos madereros a través de la plantación de otro tipo de especies, comúnmente denominadas de maderas nobles, que permitan la obtención de productos con alto valor agregado. |
