Onion cultivars Granex 33, Granex 429, Texas Grano 502, Texas Grano 1025 Y, Texas Grano 1105 Y, FMX-225, Texas Grano 1030 Y, Texas Early Grano 502 and Texas Grano 1015 Y were evaluated at the Fortuna Agricultural Experiment Substation in Juana Díaz, P, R. from late November 1985 to early April 1986. Granex 33 and Granex 429 gave highest marketable yields: 33,075 and 32,194 kg/ha, respectively. These yields were significantly higher than yields of other cultivars except Texas Grano 502. These cultivars were also the best in terms of size classification. There were no significant differences in average bulb weight among most of the cultivars. Granex 33 had the highest density and Texas Grano 1030 Y had the highest percentage of total solids.
