Vegetable cultivar evaluations are conducted seasonally by research and extension faculty at several locations throughout the state of Florida. Results are summarized and published in a Florida Agricultural Experiment Station Circular, Vegetable Variety Evaluation in Florida and used as a basis for extension recommendations published in Vegetable Production Guide for Florida, an industry-sponsored publication. The selection of vegetables to be evaluated depends on local needs and the evaluator's interest. Until recently, this has provided fairly good coverage of the principle vegetables grown in the state. However, the future of this program as currently structured may be in doubt because of changes in assignments of current faculty, new faculty with assignments and interests that differ from their predecessors, and reduced administrative recognition for cultivar evaluation. It is likely that county extension faculty and professional staff will have a greater role in cultivar evaluation as university faculty input is reduced. Increasing the scope of vegetable cultivar evaluation by university faculty to include adaptation of new crops and specialty vegetables adds a new dimension to traditional trials. Some of these vegetables have not benefitted from selection or breeding so there is opportunity for crop improvement as a further extension of vegetable cultivar evaluation.

Dr. Prem Nath, formerly Assistant Director General of the United Nations Food and Agriculture Organization, succinctly provides the rationale for this book in the foreword. He states that, globally, there is concern for diminishing nutritional security and that land under agriculture is dwindling, water for irrigation is becoming scarce and costly, and availability of labor is getting smaller. Hence, the need for new crops and alternate sources of nutrition is getting attention. Dr.

Abstract

Seedcoat adherence to emerged cotyledons of seedless watermelons (Citrullus lanatus (Thunb.) Matsum & Naki) results in distortion of seedlings that effectively restricts the number of productive plants in a planting. Significantly fewer seedcoats adhered to cotyledons when seeds were oriented with the radicle end up at a 45° or 90° angle than when seeds were oriented horizontally or with the radicle end down at a 45° or 90° angle. Emergence was not affected by seed orientation.

Abstract

Quality of horticultural crops is an extremely variable and perhaps nebulous characteristic. Quality may be easily expressed in physical terms such as size, color, or shape. Texture, food value, and keeping qualities, requiring more sophisticated determinations, are also critical components of quality. In some cases, quality may be a highly individual thing, varying from consumer to consumer. Furthermore, the expression of quality may be controlled by genetic capability as well as a host of environmental conditions.
