This paper integrates information on research studies carried out, in Stevia rebaudiana Bertoni, by the Southeast Regional Research Center (CIRSE) of the National Institute of Forestry, Agricultural and Livestock Research (INIFAP) in Mexico. Stevia is an ancient plant of Paraguayan origin with great potential to produce natural sweeteners. There is a constant demand at the national and international levels for this crop so new varieties adapted to different environments are required in order to reduce production costs, avoid dependence from abroad, improve yields and increase the acreage. The Mexican CIRSE has documented a series of innovations since 2010 in stevia such as: 1) studies of the productive potential, 2) production of seedlings with biological rooters, 3) population densities, 4) pre-emergence control of weeds, 5) fertilization doses, 6) materials better adapted to Mexican environment conditions and 7) evaluation of main stevia glycosides such as Stevioside and Rebaudioside- A among the most important. The main scientific findings are reported in this paper with the hope that stevia producers use it as a guide to improving their stevia production crop.
