ABSTRACT.- Controlling a pest species raises questions about the harmful effects its eradication could cause in ecosystems. Currently, in Uruguay are being analyzed strategies to eradicate the New World Screwworm (NWS), Cochliomyia hominivorax (Diptera:Calliphoridae), an obligatory ectoparasite that causes myiasis in warm-blooded vertebrates, including humans. The loss of a species implies a risk of secondary extinctions and cascading effects that depend on the ecological function of the species and the capacity of the rest of the species with which it interacts to compensate for its loss.

Agrociencia Uruguay was founded 25 years ago with the aim of communicating, in open access mode, the research results in the field of agriculture, mainly research carried out in the region. To fulfill this objective, and given the different disciplines that make up the agricultural sciences, the journal was divided from its origin until the present into sections in which original knowledge is published.

El objetivo del presente trabajo es mejorar la calidad nutricional del grano de soja, a través de la edición de genes que controlan el tamaño y composición del grano. Este trabajo se centró en generar mutaciones de tipo knockout en genes asociados con el tamaño de la semilla (BS) y con la calidad de proteínas de grano, utilizando el sistema CRISPR-Cas9.

This study aimed to validate the use of two SNP markers associated to a sdw1 allele identified previously in a short barley genotype (ND23049) with an adequate peduncle extrusion which reduces predisposition to fungal disease development. First, the GBS SNP were converted in a KASP marker but only one of them, named TP4712, correctly amplified all allelic variations and had a Mendelian segregation in a F2 population. To corroborate the association between TP4712 allele with plant height and peduncle extrusion, a total of 1221 genotypes were genotyped and evaluated for both traits.

El presente artículo pone el foco en una nueva biotecnología que INIA se encuentra evaluando para el control de la chinche de la soja. Los bioplaguicidas basados en ARNi forman parte de una estrategia de manejo de plagas amigable con el ambiente y con bajo impacto en especies no blanco, requerimientos necesarios para una agricultura sostenible.

ABSTRACT.- Ergot disease (Claviceps paspali) and sterility have the potential to reduce seed yield in bahiagrass (Paspalum notatum Fluggé). Our objective was to determine the genotypic and environmental effects on seed yield, and the levels of ergot and sterility. Seventeen genotypes were evaluated in three locations across two years for seed yield, ergot severity, and total seed fractions (percentage of full seeds, ergot sclerotia and empty seeds).
