The objective of this study was to discriminate and select guava genotypes to improve the crop production system in the Submiddle of San Francisco Valley. An experiment was carried out at the Bebedouro Experimental Sation that belongs to Embrapa Semiarid in Petrolina, State of Pernambuco, with five genotypes of guava: Paluma, Red Fleshed, Surubim, Red Selection of Florida and Ruby Supreme. A randomized block design was used as statistical model with five treataments, and five repetitions. The results, related to the first and the second fruit set prunings and two year of combined analyses for fruit yield, indicated that Surubim variety tended to higher yield and greater number of fruits among the five genotypes tested.
