Fourteen sweet corn F1 Hybrids were tested in a grower commercial field in La Costa de Hermosillo, Mexico 70 km west far away Hermosillo City during 2006 spring season. A completely randomized experiment design was utilized. The plots were established under a drip irrigation system considering 1.8 m apart between each drip irrigation line and 50 cm between row plants. Eight corn seeds were sowed per lineal meter (approximately a population of 90,000 plants per ha). The evaluated sweet corn F1 Hybrids were: Challenger, Shimmer, Krispy King, GSS-4644, GSS-7831, Prime Time, Forever, 4404, GSS-5788, GSS-9377, GSS-1526, Show Case, Prime Plus, and GSS-9299. According to results recorded in this field sweet corn F1 Hybrids evaluation, most Hybrids reached high yield and quality for international market. All sweet corn Hybrids were harvested 65 days after sowing. The sweet corn Hyd. SS-9377 recorded the longest ear sized. Highest sugar levels were recorded up to 16 ºbrigs in Shimmer, Krispy King, GSS-7831, and GSS-9377 F1 Hybrids. Remaining sweet corn Hybrids reached 13 ºbrigs. When packing, cartoon boxes of four dozens ears capacity were used. Regarding to crop production, GSS-4644, Krispy King, Shimmer, and Challenger were the most outstanding F1 Hybrids recording yielding ranging from 907 to 1176 boxes per ha.
