Sixty-seven lines, selections and varieties of guava (Psidium guajava) were planted in 1971 at the Fortuna Experiment Substation, Juana Diaz in the south central region of Puerto Rico to observe their behavior and fruit quality. Fifty four were still thriving in 1991. During the 1991 and 1992 seasons, fruits were harvested for evaluation as to appearance, flavor, Brix, Ph, acidity, percentage of reducing sugars and percentage total sugars. Several varieties achieved acceptability, depending on the criterion used. However. 57-6-107. R-264. D-18, 57-6-79 and G-447 selections appear to be the highest rated as to flavor and appcarance. Other varieties were found acceptable in terms of the various parameters studied. Unacceptable fruits (as to flavor) were rejected due to their high acidity.
