Characterization and evaluation of cuban

soybean collections, is one of the initial steps in germplasm

potentiation of this species, in order to use it in development

and breeding programs. In the present work, 50

cultivars from the cuban soybean collection were preliminary

classified, considering the most variable attributes. The cultivars

were grouped as early, intermediate and late ones, according

to days to bulk flowering. Most promising cultivars were

outstanded in the early and intemediate plus late groups,

repectively; these cultivars are recommended for their inclussion

in the breeding programs of the species.
