Eucalyptus globulus Labill. is of great interest to the pulp industry. However, the species is highly susceptible to leaf spot caused by Teratosphaeria nubilosa and has a low rooting capacity. In order to overcome these limitations, INIA has been implementing a genetic improvement program for this species and the generation of interspecific hybrids. The strategy is based on the selection of E. globulus clones with high precocity or foliage turnover, since the adult foliage is more tolerant to T. nubilosa. In addition, controlled crosses of E. globulus and E. maidenii with E. grandis are carried out to incorporate disease resistance and ease of rooting. |

ABSTRACT.
Bacterial leaf spot of tomato is caused by four Xanthomonas species, among which Xanthomonas vesicatoria race T2 predominates in Uruguay. Difficulties in integrated disease management and the rapid spread of the pathogen led to investigations of genetic resistance. This study aimed to identify resistance sources to bacterial leaf spot race T2 in tomato for processing. Twelve genotypes were evaluated under field conditions in 2010 and 2011. Plants were spray-inoculated with a suspension of bacteria (108 cfu/mL) 15 days after transplantation. Incubation period, disease severity on leaves, and the percentage of fruits with symptoms at harvest were determined. The incubation period did not differ among the genotypes. The genotype 'Hawaii 7981' had the lowest leaf severity on the leaves, followed by 'Loica'. The lines (derived from the cultivar 'Loica') LB97, LB99, LB60, and LB76, and the cultivar 'Ohio 8245' showed intermediate levels of severity on leaves, whereas 'H9997', 'Cuyano', LB85, and 'NUN6011' presented higher severities. The differences in disease severity of the leaves were similar over the years, while incidence of symptoms in fruit was more variable. Next to 'Hawaii 7981', the cultivars 'Loica' and 'Ohio 8245' were identified as new sources of partial resistance to bacterial spot race T2.
RESUMO.
A mancha bacteriana do tomateiro é causada por quatro espécies de Xanthomonas, sendo Xanthomonas vesicatoria raça T2 a predominante no Uruguai. O manejo químico e cultural desta doença não tem sido suficiente para o seu controle; portanto, o melhoramento genético para gerar genótipos resistentes é uma estratégia importante que deve ser incluído para contribuir no manejo integrado desta doença. O objetivo do presente trabalho foi identificar fontes de resistência à mancha bacteriana foliar raça T2 do tomateiro para indústria. Doze genótipos foram avaliados no campo em 2010 e 2011. As plantas foram inoculadas com uma suspensão da bactéria (108 cfu/mL) aos 15 dias depois do transplante. O período de incubação, a severidade da doença e a percentagem dos frutos com sintomas foram determinados. Não houve diferença no período de incubação entre os genótipos. O genótipo 'Hawaii 7981' teve o menor valor de severidade nas folhas, seguido da cultivar 'Loica'. As linhagens (derivadas de 'Loica'), LB97, LB99, LB60 e LB76 e a cultivar 'Ohio 8245' tiveram um nível intermédio de severidade nas folhas, ao passo que 'H9997', 'Cuyano', LB85 e 'NUN6011' apresentaram severidades mais altas. As diferenças entre os genótipos no nível de severidade da doença foram consistentes entre os anos, porém, a incidência nos frutos foi mais variável. Junto à 'Hawaii7981', 'Loica' e 'Ohio 8245' foram identificados como novas fontes de resistência parcial à mancha bacteriana raça T2. MenosABSTRACT.
