ABSTRACT: Participatory plant breeding uses a concept that joint formal (official researches institutions) and informal sector (farmers communities), combining the capabilities and the knowledge of both, and farmer's experiences, practices, and preferences. The goal is to join the yield improvement exploring the availabel farmer's agrobiodiversity and introduction new sources of genetic materials. Another goal is to develop the farmer's capability to select and to interchange seeds. Generally, participatory breeding has been used in areas under stress conditions. These areas are usually related with agriculture of subsistence, where farmer's do not have funds to buy seeds, fertilizers, and pesticides. Small farmers need varieties adapted to their specific local conditions and these materials can reduce the cost of production. The objective of this work was to present a review about different approaches in genetic plant breeding and the concept of participatory breeding. Besides, it describes a pionner work in participatory breeding in Brazil carried out with farmers belonging to the settlement "Sol da Manhã" (Seropédica, State of Rio de Janeiro). Low levels of nitrogen in soils are the main local stress condition. The result of this experience was the development and the release of the maize variety "Sol da Manhã". |

Gibberellins have been shown to suppress floral development in mango, thus farmers have used growth retardants, especially paclobutrazol, to inhibit gibberellin biosynthesis, but in many countries such as Brazil, this is the unique registered molecule, which affects sustainability of the mango industry. The objective of this study was to evaluate the effect of metconazole on gibberellin biosynthesis inhibition and carbohydrate accumulation in ?Palmer? mango grown in semi-arid conditions. The experiment was accomplished from 2015 to 2017 in an experimental orchard located in Petrolina, Pernambuco, Brazil. The experimental design were randomized blocks with five treatments, five replications and three plants per replication. The treatments consisted of metconazole (0, 0.7, 1.0 or 1.3g) and paclobutrazol (1.0g) application per linear meter of plant canopy. According to the results, metconazole efficiently inhibits gibberellin biosynthesis in mango, but it affects AG1+AG3 (Gibberellic Acid) and AG4 differently. Therefore, metconazole can potentially be used on mango flowering management, but further studies are required to determine specific management practices. |
