ABSTRACT - Mandarin cultivars show a great diversity of fruit-quality and sensory characteristics, together with an extended harvest season. Citrus breeding is focused on exploiting season niches for higher prices as well as nutritional and sensory aspects, among others. In this context, the sensory characterization of new hybrids and the identi-fication of key characteristics of consumers ? liking provide valuable information towards breeding efforts and marketing strategies. Previous works showed that sensory characteristics, and specially flavor, play a key role in consumer acceptance of mandarins. Two studies were carried out during mandarin harvest season (mid and late) applying ?check all that apply? (CATA) questions with at least 100 consumers. Overall liking scores of the most liked hybrids and cultivars ranged between 6.5 to 7.7 in the 9-point hedonic scale, evidencing a positive hedonic reaction. Local hybrids showed similar or higher values than the reference cultivars Tango, Gold Nugget, Murcott and Ortanique. Results showed that orange color, regular shape, smoothness, sweetness, juiciness, int ense and typical flavor are the key drivers of consumer's liking of mandarins, and that external appearance is not a good predictor of mandarin tasting experience. Hybrids F3P8, F5P8 and F2P3 were described using terms related to positive sensory characteristics and received liking scores similar or higher to reference cultivars such as Tango, stressing the importance of sensory and consumer science as an integral part of breeding strategies.

RESUMEN - Las mandarinas presentan una gran diversidad en características sensoriales y de calidad de fruta, así como una cosecha extendida. El mejoramiento genético de cítricos se focaliza en la búsqueda de nichos de cosecha para la obtención de mayores precios, así como en aspectos nutricionales y sensoriales, entre otras caracterís-ticas. En este contexto, la caracterización sensorial de nuevos híbridos y la identificación de las características sensoriales claves que influyen en la aceptabilidad de los consumidores proveen de una valiosa información para el mejoramiento y las estrategias de marketing. Estudios previos mostraron que las características senso-riales, especialmente el sabor, son claves en la aceptación de las mandarinas por los consumidores. Se llevaron a cabo dos estudios durante la estación de cosecha de mandarinas (media y tardía) aplicando la metodología «marque todo lo que corresponda» (CATA) y con la participación de al menos 100 consumidores. La aceptabi-lidad de los cultivares que fueron más aceptados se situó entre 6,5 y 7,7 en una escala hedónica de 9 puntos, evidenciando una reacción hedónica positiva. Los nuevos híbridos presentaron puntajes de aceptabilidad simi-lares o superiores a los cultivares de referencia Tango, Gold Nugget, Murcott y Ortanique. A su vez, los resul-tados mostraron que el color naranja, la forma regular, la piel lisa, el dulzor, la jugosidad, el sabor intenso y el sabor típico a mandarina son características claves que determinan la aceptabilidad de las mandarinas, y que la apariencia externa no es un buen predictor del sabor. Los híbridos F3P8, F5P8 y F2P3 fueron descritos por los consumidores con términos sensoriales positivos, recibiendo valores de aceptabilidad similares o mayores que los cultivares de referencia como tango, reafirmando la importancia de la incorporación de estudios senso-riales en el contexto del mejoramiento genético.

RESUMO - As cultivares de tangerina apresentam grande diversidade na qualidade dos frutos e nas características senso-riais, juntamente com uma época de colheita prolongada. O melhoramento cítrico tem como foco a exploração de nichos sazonais por preços mais elevados, além de aspectos nutricionais e sensoriais, entre outros. Nesse contexto, a caracterização sensorial de diferentes híbridos e a identificação das características-chave do gosto do consumidor fornecem informações valiosas para os esforços de melhoramento e estratégias de marketing. Trabalhos anteriores mostraram que as características sensoriais e principalmente o sabor desempenham um papel fundamental na aceitação das tangerinas pelo consumidor. Dois estudos foram realizados durante a safra de tangerina (meio e final) aplicando perguntas do tipo cheque todos que se aplicam (CATA) com pelo menos 100 consumidores. As pontuações de aceitação geral dos híbridos e cultivares mais apreciados variaram entre 6,5 a 7,7 na escala hedônica de 9 pontos, evidenciando uma reação hedônica positiva. Os híbridos locais apresentaram valores semelhantes ou superiores aos cultivares de referência Tango, Gold Nugget, Murcott e Ortanique. Os resultados mostraram que a cor laranja, formato regular, maciez, doçura, sabor intenso y sabor tangerina e suculência típicos são os principais motivadores do gosto do consumidor por tangerinas e que a aparência externa não é um bom indicador da experiência de degustação da tangerina. Os híbridos F3P8, F5P8 e F2P3 foram descritos usando termos relacionados a características sensoriais positivas e receberam pontu-ações de gosto semelhantes ou superiores a cultivares de referência como o Tango, enfatizando a importância da ciência sensorial e do consumidor como parte integrante das estratégias de melhoramento.

ABSTRACT.
Serratia marcescens is a Gram-negative bacterial species that can be found in a wide range of environments like soil, water and plant surfaces, while it is also known as an opportunistic human pathogen in hospitals and as a plant growth promoting bacteria (PGPR) in crops. We have used a pangenome-based approach, based on publicly available genomes, to apply whole genome multilocus sequence type schemes to assess whether there is an association between source and genotype, aiming at differentiating between isolates from nosocomial sources and the environment, and between strains reported as PGPR from other environmental strains. Most genomes from a nosocomial setting and environmental origin could be assigned to the proposed nosocomial or environmental MLSTs, which is indicative of an association between source and genotype. The fact that a few genomes from a nosocomial source showed an environmental MLST suggests that a minority of nosocomial strains have recently derived from the environment. PGPR strains were assigned to different environmental types and clades but only one clade comprised strains accumulating a low number of known virulence and antibiotic resistance determinants and was exclusively from environmental sources. This clade is envisaged as a group of promissory MLSTs for selecting prospective PGPR strains.
