Expression of catalase, alcohol dehydrogenase, and malate dehydrogenase in rot grains upon fungicide use on maize hybrids grown at different spacings
In this study, we evaluated the fungicide effect on the incidence of rot grains and expression of catalase (CAT), alcohol dehydrogenase (ADH), and malate dehydrogenase (MDH) enzymes in commercial maize hybrids grown with conventional and reduced spacing in Guarapuava, PR, Brazil. The experiment was designed in random blocks with a 3 × 8-factorial scheme, total.. Read More»

Prediction of industrial tomato hybrids from agronomic traits and ISSR molecular markers
Heterosis is a highly relevant phenomenon in plant breeding. This condition is usually established in hybrids derived from crosses of highly divergent parents. The success of a breeder in obtaining heterosis is directly related to the correct identification of genetically contrasting parents. Currently, the diallel cross is the most commonly used methodology to dete.. Read More»

ms17: a meiotic mutation causing partial male sterility in a corn silage hybrid
Cytological analysis under light microscopy of the single hybrid P30R50 of silage corn revealed an abnormal pattern of microsporogenesis that affected the meiotic products. Meiosis progressed normally until diakinesis, but before migration to the metaphase plate, bivalents underwent total desynapsis and 20 univalent chromosomes were scattered in the cytoplasm. At th..

Meiotic behavior as a selection tool in silage corn breeding
In breeding programs, commercial hybrids are frequently used as a source of inbred lines to obtain new hybrids. Considering that maize production is dependent on viable gametes, the selection of populations to obtain inbred lines with high meiotic stability could contribute to the formation of new silage corn hybrids adapted to specific region. We evaluated the meio.. Read More»

Indirect selection of industrial tomato genotypes that are resistant to spider mites (Tetranychus urticae)
Acyl sugars present in the tomato Solanum lycopersicum ‘LA-716’ accession confer good levels of resistance to arthropod pests. The objective of the present study was to select F2 plants from the interspecific cross Solanum pennellii ‘LA-716’ x Solanum lycopersicum ‘Redenção’ to assess resistance to spider mites (Tetranychus urticae) based on the..

Selection of processing tomato genotypes with high acyl sugar content that are resistant to the tomato pinworm
Acyl sugars are allelochemicals present at high concentrations in leaves of accessions of the wild tomato Solanum pennellii; they confer resistance to a large number of arthropod pests, including the tomato pinworm, Tuta absoluta (Lepidoptera, Gelechiidae). Accession 'LA716', with high contents of acyl sugars in the leaves, was used as a source of resistance to start a genetic breeding program .. Read More»

Indirect selection of industrial tomato genotypes rich in zingiberene and resistant to Tuta absoluta Meyrick
Obtaining tomato cultivars resistant to pests through interspecific crosses between commercial cultivars and wild accessions is an important tool in integrated pest management. The aim of this study was to select tomato genotypes with high zingiberene (ZGB) levels that are resistant to the South American tomato moth (Tuta absoluta Meyrick) and to estimate g.. Read More»

Genetic divergence among corn hybrids and combining ability for agronomic and bromatological traits of silage
We assessed the impact of genetic divergence and the ability to combine corn hybrids used for the production of silage on the agronomic and bromatological traits of silage quality. We evaluated 18 corn hybrids used as genitors in a circulant diallel scheme in which each genitor hybrid participated in 9 hybrid combinations, and evaluated 100 treatments [18 genitor hy..
