The new sorghum variety Gavatero-203 was developed at Culiacán Valley Experiment Station of the National Research Forestry, Agriculture and Livestock Institute (INIFAP) and was registered with the number 2205-SOG-529-090209/C in the Catalogue of Feasible Varieties of Certification in Mexico. This variety is adapted to sorghum-producing areas in State of Sinaloa, Mexico.The variety Gavatero-203 has red grain and is recommended either for irrigation and rainfall areas. The average yield of the variety is 2 849 kg ha^-1 of grain and 35 367 kg ha^-1 of green forage, which is 18.5% and 15.4% higher than the grain and fresh forage yield of commercial hybrids from private companies cultivated in the region. Gavatero-203 has better bromatologic quality in the forage than commercial hybrids, with 7.3% of protein and 66.4% of digestibility, which is 1% and 6% higher than commercial hybrids. It is tolerant to ergot (Claviceps african), anthracnose (Colletotrichum graminícola), head blight (Fusarium moniliforme) and charcoal rot (Macrophomina phaseolina). The forage of Gavatero-203 can be used either for hay and silage.
