Rice and wheat are the two main sources of calories in the human diet, and both are important crops that are exported to the USA. Rice blast, which is caused by the Magnaporthe oryzae fungus, is a limiting factor for the global production of rice and constitutes a very serious emerging threat to wheat in the USA. Research on the disease in last the 20 years has provided a wealth of understanding on the molecular foundation for rice resistance to blast and on M. oryzae's pathogen

Spittlebug, Mahanarva spectabilis (Hemiptera: Cercopidae) is capable to cause drastic losses in production and quality of pastures established with grasses. Currently, the use a grass resistant cultivar, to be obtained by means of constitutive antibiosis, is the best spittlebug controlling method. However, the time required for releasing a cultivar after detecting a spittlebug-resistant strain is relatively long. Allied to this, one should take into consideration that the adaptations of

GM crops that are resistant to glyphosate have created a new scenario in Brazilian agriculture. Glyphosate has been generally used mainly in soybean farms in the Brazilian states of Rio Grande do Sul, Santa Catarina and Paraná. In the state of São Paulo, glyphosate is widely used in orchards, especially citrus ones. The repeated use of glyphosate has given rise to cases of weed resistance to this herbicide in different places of the country. The trend is that new glyphosate resistant crops such ...

The program of genetic improvement of the cupuaçu tree ( Theobroma grandiflorum) needs to tend to the demand of new cultivares, especially of those resistant to the Monilophthora perniciosa fungus, the agent responsible for causing the deformity known as witch's broom disease, and also to increase as much as possible the genetic base of planting material. This project aims to develop new technologies which promote the quick multiplication of selected cultivares, as well as to early select ...

Along with current demand for palm oil ("dendê" oil) by the industries of food, pharmaceuticals, chemicals, and bio-fuel, it is important to encourage the advance of researches regarding handling techniques that allow longevity, increase in cultivated areas and productivity of the Palm Oil Tree ( Elaeis guineensis Jacq.).

Great part of the country's culture of palm oil is concentrated in the Amazon region, with the state of Pará as its largest producer (93%). However, a great obs ...

The control of spittlebugs, in general, is compromised by the failure to recognize that the impact of this insect pest can vary greatly, due to taxonomic diversity, the extent of habitats, climatic factors and pasture management. Furthermore, insects and plants co-evolve and this factor must be taken into account, since the discovery of resistant cultivars requires a relatively long period and the knowledge of the bases of the insect-pest interaction with the plant can be a key point for the ree

In last the two decades, the melon agribusiness in Brazil has expanded nine times, reaching a production that is estimated at 500,000 tons per year and is concentrated in the Northeast. Since 2007, melons have become the main national fruit in volume of exports, and in 2008 Brazil was the second top world exporter. Nearly all melon cultivars planted in the Northeast are imported, and hence there is demand for more adapted ones, as the cultivars available were generally developed in soil and clim

Smallholder Capsicum pepper growers in Uganda are operating below the ideal levels of agricultural production due to a lack of improved varieties, low quality seed systems and the devastation caused by pests and diseases. The damages caused by diseases are aggravated by the cultivation of susceptible germplasm and the use of poor quality seeds. In order to increase production and competitiveness in the market, farmers need to have access to clean seeds of cultivars that are tolerant to diseas

Brazil annually consumes 10.5 million tons of wheat, half of which is produced in the country, which entails an approximate outlay of 800 million dollars in wheat imports. The high cost of production and the difficulties in the obtention of cultivars with technological qualities that meet market requirements are among the main limiting factors for the Brazilian wheat production chain. Out of all the cultivars available from all Brazilian breeders, about two thirds were created from germplasm
