THE RIDESA
The Inter-University Network for the Development of Sugarcane and Energy was formed through a technical cooperation agreement between ten Federal Universities. Thus, RIDESA's research activities are developed and shared among all universities, encouraging the exchange of information, knowledge and results. This greatly increases the capacity and national scope of research and innovation results. Therefore, the Network operates at a national level and is currently the main center for sugarcane research within the Federal Government.
The definition of the nomenclature of sugarcane varieties in the RIDESA network uses the acronym RB “Republic of Brazil”, which is registered with the Germplasm Committee of the International Society of Sugar Cane Technologists – ISSCT . The numbering is followed by the year of crossing and then by the code for the respective University, which represents the location of selection of the variety, as detailed in Table 1 below.
Table 1. Coding by letters and numbers for RIDESA Sugarcane RB clones, 2015.

In order for these new varieties to be created, RIDESA has 79 research bases, including University Laboratories, Crossing Stations, Experimental Stations and Selection Bases, the latter being conducted in partnership with companies in the sugarcane sector.
RIDESA has produced 75 cultivars since 1990, which, together with the cultivars released by PLANALSUCAR, total 94 RB varieties, produced in 45 years of sugarcane research. Currently, the network accounts for 68% of the total area cultivated with this plant in Brazil.
