| Molecular genetics is an additional tool which provides information for the detection and exploitation of genes or chromosomal regions with large influence on economic traits. This comes from the development of dense maps of linkage disequilibrium among genetic markers for many livestock species. Although each type of genetic marker has advantages and disadvantages, the only polymorphisms with enough density to meet important requirements for gene mapping are the Single Nucleotide Polymorphisms Status: Completed Start date: Tue Jan 01 00:00:00 GMT-03:00 2013 |
| The use of nanotechnology has been putting nanoparticles and nanostructures in contact with live organisms in ways not yet fully understood. In agriculture, this interaction can occur on a large scale, such as in the applications of controlled release nanostructure-encapsulated pesticides whose toxicity inherent to the drug release system still requires continual verification. Cases like this have motivated the proposal of this project, whose objective was to evaluate the potential impact on liv Status: Completed Start date: Fri Apr 01 00:00:00 GMT-03:00 2011 |
| Brazilian native fruit species are excellent generators of income and job opportunities to family farmers and micro-entrepreneurs especially from the Northern and Northeastern regions of Brazil. Species such as the Platonia insignis, Myrciaria dubia, Byrsonima crassifolia and the Spondia mombin L. have been frequently cited as economically promising in the field of family farming, due to the myriad of business possibilities linked to the ever increasing demand of Status: Completed Start date: Fri Feb 01 00:00:00 GMT-03:00 2008 |

| Genetic Vegetable resources, globally, involve a number of around 300,000 identified species, of which 30,000 are edible and only 30 consist of foods that feed the world's population. However, from this total, only three species provide 50% of proteins necessary in a regular diet (rice, wheat and corn). This situation has been stimulating a great number of researchers in the quest to increase the number of species dedicated to feed the population. Brazil is considered the world's greatest source Status: Completed Start date: Thu Jan 01 00:00:00 GMT-03:00 2009 |
| Germplasm banks have as their main purpose to get together in one place part of the genetic variability (germplasm), in order to prevent the loss of genes or gene combinations (genetic erosion), thus ensuring a broad genetic basis for research programs. Germplasm banks are usually made up of local races (ethnovarieties), improved varieties and wild species of the same genus. And because they bring together genetic constitutions of different origins and different breeding levels, they can be grea Status: Completed Start date: Thu Jan 01 00:00:00 GMT-03:00 2009 |
| This project aims to develop, evaluate and validate the environmental and social sustainability of technical-economic milk production systems based on Integrated Crop-Livestock-Forest Systems (ICLFS), with the use of the main plant species silage corn, cowpea, Piata grass, eucalyptus, chestnut; and Dutch x Gir crossbreeds.

| The development of new technologies for the agricultural sector from cutting-edge areas such as nanotechnology is a demand Embrapa has recognized. The crosscutting and pervasive nature of developments in this area also makes it difficult to understand models that allow these new technologies to actually reach the production sector. It is evident that when a company in the food sector assimilates new technology, its behavior is structurally different from that of a company in the plastics industr Status: Completed Start date: Fri Apr 01 00:00:00 GMT-03:00 2011 |
| raditional breeding has generated significant genetic gain over time. However, this strategy falls short of yielding information on the biological processes involved. Additionally, there are great difficulties for the genetic improvement of characteristics which are measured solely in one gender and/or late in the life span of the animal. With the development of DNA chips it became possible maximizing genetic gain by reducing the generation interval and increasing the intensity of selection. The Status: Completed Start date: Wed Sep 01 00:00:00 GMT-03:00 2010 |
| Agricultural systems basically depend on ecological processes and services provided by ecosystems. These ecological processes and services, called ecosystem services or environmental services, relate to the conditions and processes through which ecosystems sustain human life by supplying provisions (food, timber, fiber and fuel production), regulation (of water, of climate, protection against droughts, flooding, storms, spread of diseases and soil degradation, waste purification), support (hydro Status: Completed Start date: Thu Mar 01 00:00:00 GMT-03:00 2012 |
