AbstractBased on acreage, broccoli is the third largest vegetable crop in Yuma County, after head lettuce, and romaine. It generates over $36 000000 a year. Efforts are continuously made by both seed industry and growers to grow better varieties that respond to consumers’ choice. Selection of newly adapted varieties is made based on agronomic performance as well as commercial value. Stand uniformity, disease resistance, color, head shape, and head size are among characteristics that are evaluated. The objective of this demonstration trial is to evaluate the characteristics of new varieties grown under standard cultural practices. Twelve varieties were tested at Yuma Agricultural Research Center. No incidence of disease was observed and the overall evaluation rating was greater than 4 indicating that all varieties tested will do well under similar growing conditions and planting date. Significant head diameter and plant height were observed among varieties tested.
