Broccoli as an altemative crop satisfies both requirements. Currently, broccoli is the fastestgrowing vegetable in tenns oE popularity in the United Stales (1). The increased cons umption of processed brOCCX>li is refiected l ocaUy by the increasing demand in South Texas by the írozen food industry. However, many problems h ave limite<l the establishment oí broccoli as a major crop in the Winter Carden. One such problem has been variety selection.
