Resumo
The preliminary work with vegetables was described and special reference was-made to the group Brassica oleracea. a) Plants flowering easily in Piracicaba and probably in the whole State of São Paulo. To this group belongs the lettuce, endive, chichory, carrot, radish, kale, brocoli and cauliflower. b) Plants where special treatment is necessary for flowering, as cabbage. c) Plants that did not flower up to this moment, as Svisschard beet and beet. Three main factors contribute for the seedless condition in the group cabbage : lack of flowering, anormalities of the flowers and self-sterility. The preliminary experiments in controling these factors seem to indicate the possibility of seed production in this group. The systematics of the two species Brassica oleracea (Europe) and Brassica juncea (Oriental Asia) was discussed. The economical differences in the group Brassica oleracea are controled by Mendelian factors with complicate types of interaction. It is not necessary to look for special places in the State of São Paulo for vegetable experiments but the possibility of better results in the future, with appropriate conditions, is emphasized.

SUMMARY
The preliminary work with vegetables was described and special reference was-made to the group Brassica oleracea.
a) Plants flowering easily in Piracicaba and probably in the whole State of São Paulo. To this group belongs the lettuce, endive, chichory, carrot, radish, kale, brocoli and cauliflower.
b) Plants where special treatment is necessary for flowering, as cabbage.
c) Plants that did not flower up to this moment, as Svisschard beet and beet.
Three main factors contribute for the seedless condition in the group cabbage : lack of flowering, anormalities of the flowers and self-sterility. The preliminary experiments in controling these factors seem to indicate the possibility of seed production in this group.
The systematics of the two species Brassica oleracea (Europe) and Brassica juncea (Oriental Asia) was discussed. The economical differences in the group Brassica oleracea are controled by Mendelian factors with complicate types of interaction.
It is not necessary to look for special places in the State of São Paulo for vegetable experiments but the possibility of better results in the future, with appropriate conditions, is emphasized.
