A reação de 23 genótipos de girassol à mancha de Alternaria foi avaliada em dois experimentos de campo, conduzidos em Londrina, PR, nas safras 2009/2010 e 2010/2011. Os experimentos foram semeados em outubro de 2009 e outubro de 2010. A severidade da doença, que ocorreu por infecção natural das plantas pelo fungo, foi avaliada na fase de desenvolvimento R3, utilizando uma escala diagramática da doença. Após a colheita, também foram avaliados o rendimento de aquênios, o peso de mil aquênios e o teor de óleo. Em cada experimento, verificou-se diferença estatística significativa entre os híbridos avaliados em condições de campo, tanto para a severidade de A. helianthi, quanto para os componentes de produção. Nenhum genótipo de girassol apresentou resistência completa à mancha de Alternaria. REACTION OF SUNFLOWER GENOTYPES TO ALTERNARIA LEAF SPOT (Alternaria helianthi) IN FIELD CONDITIONS DURING 2009/2010 AND 2010/2011 GROWING SEASONS. The reaction of 23 sunflower genotypes to Alternaria leaf spot disease was evaluated in two field experiments carried out in Londrina, state of Paraná, Brazil, during 2009/2010 and 2010/2011 growing seasons. The experiments were sown in October 2009 and October 2010. Alternaria disease severity, under natural conditions in the field, was evaluated at the R3 growth stage with reference to a diagrammatic scale developed for this disease. After harvesting, yield, 1000-seed weight and oil content were also evaluated. For each experiment, statistical significance was observed among the evaluated genotypes for disease severity and yield components. None of the sunflower genotypes showed complete resistance to Alternaria leaf spot.

Peanut or groundnut (Arachis hypogaea L.) is a globally important oilseed crop, with important nutritional qualities, and a rich source of amino acids and protein. Another 80 species have been described in the genus Arachis, 64 of which are found in Brazil, and even though their morphology and agronomic traits remain largely unknown, they have been cultivated for forage and for landscaping and have great potential for breeding with cultivated peanut. Thus, the morphological characterization of wild Arachis species is essential for their conservation and use. In this study, we present a morphological and agronomic characterization of 29 diploid accessions of eleven wild Arachis species and one of the tetraploid A. monticola (section Arachis) with A and B genomes and determine their intra- and interspecific variability in greenhouse and field conditions. In total, 35 morphological descriptors were developed a priori from greenhouse accessions in the first crop year and used in field accessions in the second crop year. Significant differences in descriptors compiled in the greenhouse and the field support the use of different descriptors for different experimental conditions. PCA analysis showed that the distribution of accessions accorded with the taxonomy of species. The ten morphological descriptors that were important in differentiating section Arachis accessions were seed length, lateral branch length, right apical leaflet length, right apical leaflet width, height and diameter of main stem, branch color, standard petal base color, number of flowers, and presence of bristles on rachis.
