In this paper the results obtained in 1966 at the Experimental Station of Monte Alegre do Sul are presented about strawberry variety trials. In all of them, variety «Dr. Morère», also known as «Comum», formerly the most cultivated in the State of São Paulo, was used as check plant. Nine varieties were studied. The total yield of June to December and also the partial one of June-July was studied, when the prices of strawberry are the highest, because harvest is beginning and also because fruits are bigger. The statistical analysis of data obtained showed the following results: a) concerning the total yield, variety Monte Alegre IAC-3113 without differing from varieties Camanducaia IAC-3530, Hybrid IAC-3432 and Hybrid IAC-2748, was superior to all the others (Campinas IAC-2712, Hybrid IAC-2529, Hybrid IAC-2747, Hybrid IAC-3592 and Dr. Morère I-699) to the level of 5%; b) considering the partial production, variety Monte Alegre IAC-3113 was superior to all the others to the level of 1% and variety Campinas IAC-2712, without differing from variety Monte Alegre IAC-3113, was superior to all the others to the level of 1%. Among the varieties studied the following have shown the best qualities: Monte Alegre IAC-3113, Campinas IAC-2712 and Camanducaia IAC-3530.
