1. A crop model-based approach for sunflower yields
Pushed by the Brazilian biodiesel policy, sunflower (Helianthus annuus L.) production is becoming increasingly regarded as an option to boost farmers' income, particularly under semi-arid conditions. Biodiesel related opportunities increase the demand for decision-making information at different levels, which could be met by simulation models. This study aim

2. Extracting female inbred lines from commercial sunflower hybrids.
The objective of this study was to obtain female inbred lines from sunflower (Helianthus annuus) hybrids. A methodology based on altering inbred lines carrying the fertility restorer gene (Rf) obtained from self pollinating hybrids into inbred lines with normal cytoplasm without the Rf gene was described. Further, derived male-sterile inbred lines were devel

3. Caracterização dos grãos, torta e óleo de três variedades de girassol (Helianthus annuus L.) e estabilidade do óleo bruto
The production of sunflower and the consumption of its oil has grown significantly in the last years in Brazil, due to the growing demand of the agro-industrial and commercial sectors and the superior oil quality. The use of screw-press for extracting sunflower oil becomes an alternative for small producers cultivating grains of high oil content, adding valu

4. Efficiency of different crops and corn hybrids on the use of phosphorus in cerrado soil. / Eficiências de diferentes culturas e híbridos de milho quanto a utilização de fósforo em solos de cerrado.
The Cerrado (Savannah) region has been one of main agriculture expansion area in Brasil, presenting favorable characteristics, but also limitations to crop production, mainly the low soil phophorus content and availability. The objective of the work was to evaluate the mainly recommended maize hybrids for cerrado region on the ability to absorb poorly-availa

5. A pentatricopeptide repeat-containing gene restores fertility to cytoplasmic male-sterile plants
Known in over 150 species, cytoplasmic male sterility is encoded by aberrant mitochondrial genes that prevent pollen development. The RNA- or protein-level expression of most of the mitochondrial genes encoding cytoplasmic male sterility is altered in the presence of one or more nuclear genes called restorers of fertility that suppress the male-sterile pheno
