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

The breeding programs of Dairy Gir, Guzerat, Red Sindhi and Girolando breeds are conducted at Embrapa Dairy Cattle in work integrated with the respective breeders' associations, as follows: ABCGIL (Brazilian Association of Dairy Gir Breeders), CBMG2/ACGB (Brazilian Center of Guzerat Genetic Breeding / Association of Guzerat and Girolando Breeders Brazil), ABCSindi (Brazilian Association of Red Sindhi Breeders) and Girolando Association. It also includes the participation of the following institu

Brazilian cattle farming has been constantly growing and it currently has extreme importance for agribusiness and the Brazilian economy. Brazil has the world's largest commercial cattle herd, with approximately 210 million head, and is the top beef exporter. To remain competitive in the foreign market and find better-paying niches, Brazil needs to improve the quality and security of the beef while maintaining competitive prices. Among the main causes of cattle production losses, there is the tic

This project articulates, in conjunction with the Brazilian Association of Holstein Cattle Breeders, dairy cooperatives and artificial insemination centers, the restructuring of the management of zootechnical data bases in order to carry out studies on new methodological procedures, essential for the modernization the current genetic evaluation system. The action plans include technical cooperation activities with educational and international research institutions and the affiliation of Brazil

Reproductive biotechnologies, particularly in vitro embryo production, can be useful to improve the milk productivity in Brazil by accelerating the genetic gain and reducing the intervals between generations. Genomic selection associated with reproductive biotechnology may be applied at the embryonic stage to promote the selection of embryos with desirable genetic traits and disposal of those with undesirable traits; consequently, maintenance costs of recipient cows would be reduced and efforts

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

Pepper (Capsicum spp.) is a high-yield commodity in Togo(Maatman, and the Al., 2011). The local pepper varieties are preferred and widely consumed, but there are no commercial seeds available in the market, or a Capsicum breeding program in Togo. Farmers themselves perpetuate the local varieties by collecting seeds of commercial fruits for the next sowing. Through a participatory research approach, this project aims at: 1) Selecting two local red pepper varieties and two bell pepper varieties th

This project's goal is to map the genes and/or QTLs responsible for Euchistus heros stinkbug resistance, which will contribute to the selection of resistant lineages in breeding programs, and to the decrease in grain damage and in the use of agrochemicals in soybean crops

Velloziaceae are an angiosperm family that contains the most desiccation-tolerant species (approximately 200 out of 270 species). These species are distributed among five genera: Acanthochlamys, Xerophyta, Barbacenia, Barbaceniopsis and Vellozia. More than 80% of theVelloziaceae species occur in South America, where the greatest morphological diversity is also found. The genus Vellozia comprises both desiccation-tolerant and non-desiccation-tolerant species, offering an excellent model for study

Brazil leads the research on reproduction of forage plants, but faces as a challenge the low diversity of pastures, mainly formed by apomictic plants. Apomixia - asexual reproduction by seeds - is an area of biotechnology with great potential to optimize the genetic improvement of these species, as it develops genetic materials and procedures for plant cloning by the direct use of seeds. This project proposes the determination of strategies to regulate the genes associated with the mode of repro
