| Productivity and forage quality of elephantgrass (Pennisetum purpureum) are directly affected by weed interference. The difficulty of control of these species is one of the main barriers to production and use of the forage as feedstock, as well as to the production of biomass for energy use. Despite the great progress in agro-ecological weed control techniques, herbicides are still indispensable. Thus, the rational use practices of these products should be improved in order to produce quality fo Status: Completed Start date: Fri Aug 01 00:00:00 GMT-03:00 2014 |
| The state of Pará is the largest northern producer of rice, corn and caupi beans, and the second largest soy producer. These species are cultivated in all the macro-regions of the state, where the Research and Technology Transfer Support Centers (NAPTs) of the Oriental Amazon are located. Based on this structure, this project aims to propose a strategy for the disclosure and transference of cultivars that are adequate to the region's producers' socio-economic and environmental conditions, throug ...

| Peppers of the Capsicum genus are cultivated in every Brazilian state, especially in Goiás, Minas Gerais, São Paulo, Ceará, Bahia, and Sergipe states, having a total estimated area of 5,000 hectares and a production of about 75,000 tons per year. The cultivation of peppers and bell peppers in Brazil has a strong family base and social importance since this activity is carried out predominantly by smallholder farmers and it is the main source of income for such families. Despite chili pepper bein ... Status: Completed Start date: Thu Jan 01 00:00:00 GMT-03:00 2015 |
| 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 Status: Completed Start date: Mon Jun 01 00:00:00 GMT-03:00 2015 |
| 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 Status: Completed Start date: Mon Jun 01 00:00:00 GMT-03:00 2015 |
| The cultivation of winter forage crops such as Italian ryegrass ( Lolium multiflorum) and velvet grass ( Holcus lanatus) is of extreme importance for increasing the productivity and efficiency of livestock production in the South Region and part of the Southeast Region of Brazil. However, there are few cultivars for use by farmers. The problem focused in this project is the lack of improved cultivars of temperate forage grasses, productive and adapted to the Brazilian conditions. T ...

| Develop and or recommend banana and plantain cultivars with resistance to the main pests (nematodes or rhizome borer) and diseases (black Sigatoka or yellow Sigatoka or Panama desease), and with agronomic and sensory characteristics aligned with the main demands of Brazilian fruit agribusiness. The strategy uses conventional breeding via crosses, adding advanced biology tools, focusing on reducing time and increasing the efficiency of selection of promising genotypes in the progenies, aiming at Status: Completed Start date: Sun Jan 01 00:00:00 GMT-03:00 2017 |
| The manual harvest of pepper fruits is difficult mostly due to the plants' low heights and the fruit's pungency, which causes irritation and burns the hands of harvesters. Such aspects partly explain the scarcity of labor for the pepper harvest. In addition, in the Brazilian and international market there are no jalapeño cultivars developed for mechanized harvesting. Therefore, this project aims at the development of new jalapeño cultivars adapted to mechanized harvest - with suitable plant arch ...

| Pastures of Cynodon spp. and elephantgrass ( Pennisetum purpureum Schum.) have their productivity and forage quality directly affected by weed interference. The difficulty of controlling weeds is one of the main obstacles to growing and using these forage crops as an input in animal feeding, as well as in the production of elephantgrass biomass for energy use. Despite the progress in agroecological weed control techniques, herbicides are still indispensable, especially in crops on ... Status: Completed Start date: Sat Jul 01 00:00:00 GMT-03:00 2017 |

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 ...Status: Completed Start date: Sun Apr 01 00:00:00 GMT-03:00 2012 |
