Phenotypic stability of strawberry cultivars assessed in three environments
We examined the agronomic performance and stability of strawberry cultivars in three environments, using the Annicchiarico and AMMI methods. Thirteen strawberry cultivars were evaluated (Aromas, Oso Grande, Dover, Sweet Charlie, Tudla, Festival, Camarosa, Monterey, Palomar, Portola, Camino Real, San Andreas and Albion), in the towns of Lavras-MG, Guarapuava-PR and U..

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»

Repellent effects of various cherry tomato accessions on the two-spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae)
Several studies have been conducted on resistance sources to improve the genetic resistance of farm-grown tomatoes to arthropod pests, including phytophagous mites. In the present study, we evaluate the behavior of the two-spotted spider mite on different cherry tomato accessions to identify possible sources of resistance (repellent effect) to this pest. Sixty-four .. Read More»

Acyl sugars and whitefly (Bemisia tabaci) resistance in segregating populations of tomato genotypes
The wild tomato, Solanum pennellii, is an important source of resistance genes against tomato pests. This resistance is due to the presence of acyl sugars (AS), which are allelochemicals that have negative effects on arthropod pests. There are no commercially available tomato cultivars that exhibit significant levels of resistance to arthropod pests. Therefore, this.. 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»

Genetic divergence among Brazilian garlic cultivars based on morphological characters and AFLP markers
Outside its centers of origin, garlic propagates only asexually. Since asexual reproduction leads to the absence of meiotic recombination, the main garlic cultivars available for cultivation have arisen from the accumulation of somatic mutations in early cultivars. Thus, it is common for a single clone to have different names in different regions. This study aimed to evaluate the genetic divers.. 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»

Establishment and molecular characterization of a sweet potato germplasm bank of the highlands of Paran�¡ State, Brazil
The sweet potato (Ipomoea batatas L.) is a crop of great importance in developing countries, as a food staple, for animal feed, and potentially for biofuel. Development of cultivars adapted to specific regions within these countries would be useful. To start a breeding program, the first step is the establishment of a germplasm bank. We initiated a sweet potato germplasm bank with accessions co.. Read More»

Resistance to Helicoverpa armigera mediated by zingiberene and glandular trichomes in tomatoes for industrial processing
The Helicoverpa armigera (Hübner) is a recent pest in Brazil, causing losses in tomato production in the Espírito Santo and Goiás states, in Brazil. A promising alternative to control this insect pest is the development of resistent tomato varieties. The breeding programs have aimed to introduce alleles of resistance present in the wild tomato acc.. Read More»
