Central Science 8~ 3 Library SOUTHWEST FLORIDA RESEARCH AND EDUCATION CE TER IFAS, University of Florida OCT 23 1987 Route 1, Box 2G Immokalee, Florida University of Florida Immokalee SWFREC Research Report IMM86-3 Ju y, STAKED TOMATO VARIETY TRIAL RESULTS-SPRING 1986 Paul H. Everett and Karen A. Armbresterl A replicated trial was conducted at the Southwest Florida Research and Education Center, Immokalee, Florida, during the spring season (January-May) of 1986 to evaluate the performance of twenty-eight tomato cultivars and/or breeding lines. Table 1 is a list of entries and seed sources used in this trial. EXPERIMENTAL PROCEDURE All entries were seeded in ToddR planter trays #150 (1.5 x 1.5 x 2.5 inch cell size) on December 19, 1985, and were transplanted to field plots on January 30, 1986. Field plots were arranged in randomized complete blocks with four replications of each entry. Each plot consisted of 7 plants spaced 20 inches apart in the row on raised plant beds spaced on 6 foot centers. Plant beds were irrigated with an open ditch seep system with lateral ditches spaced 41.5 feet apart. There were 5 plant beds between lateral ditches. All plots were fertilized with 7 lb of 5-16-8-1.2 and micronutrients/100 linear bed feet (LBF) applied in a 30-inch wide band on a pre-bed and bedded over to a depth of 3-4 inches and a total of 14 lb of 19-0-30/100 linear bed feet applied on the surface of the finished bed in narrow bands 10 inches to each side of the plant row. The plant beds were fumigated with VorlexR at 21 ounces/100 linear bed feet and then mulched with black plastic film. Plants were staked but not pruned. Fungicides were applied on a 5-7 day schedule and insecticides were applied as needed.'\Insects were not a serious problem in this test. Early blight was detected during late February and rapidly became scattered throughout the trial. Serious leaf damage was prevented by increased applications of fungicide sprays. General weather conditions during this trial are shown in Table 2. Tomatoes were harvested on April 25, 1986, and May 8, 1986. At each harvest fruit were graded, counted and weighed. Per acre yields are based on 7,260 linear feet of plant bed. RESULTS AND DISCUSSION Table 3 shows the marketable yields for each of the 28 entries. Marketable yields for the first harvest ranged from a high of 1001 25-lb cartons/7260 LBF for Hybrid 26 to a low of 341 25-lb cartons/7260 LBF for 'Pirate'. For highest first harvest IProfessor and biologist, respectively, IFAS, University of Florida, Southwest Florida Research & Education Center, Immokalee, Florida 33934 marketable yields, eleven entries are not significantly different from each other. They are Hybrid 26 (1001 25-lb cartons/7260 LBF), 7182 (997), ACX 5x5 (968), 'FTE 23' (896), XPH5074 (874), 'Horizon' (841), FMX 79 (831), 7175 (824), 'All Star' (804), 7181 (695), and Hybrid 724 (682). Yields from all entries were statistically equal at the second harvest and for total marketable yield. Relative maturity was determined by comparing first harvest marketable yields with the total marketable yields (Table 3). ACX 5x5 and 'Horizon' were judged to be the earliest with 38% and 37% respectively, of their fruit maturing by the first harvest. 'Pirate' was judged to be the latest entry with 16% of its fruit maturing by first harvest. Average weight of fruit for the first harvest (Table 4) ranged from a high of 6.1 oz for Hybrid 26, XPH 5074, and 'Duke' to a low of 5.2 oz for NS 264 with 21 of the 28 entries statistically equal for the largest average fruit weight. At the second harvest 7178 (6.2 oz) had statistically heavier fruit than all but one entry, XPH 5074 (5.9 oz). Overall, the heaviest fruit were produced by 7178 (6.0 oz), XPH 5074 (5.9 oz), Hybrid 26 (5.8 oz), 'FTE 23' (5.8 oz), ACX 5x5 (5.8 oz), XPH 5011 (5.7 oz), FMX 79 (5.6 oz), 'Duke' (5.6 oz) and XPH 5031 (5.6 oz). Percent cull fruit are shown in Table 4. 7178 consistently had a low percentage of culls throughout the trial with its overall cull rate significantly better than 17 of the remaining entries. Categories of cull fruit, by harvest, are shown in Table 5. Large and leaky blossom-end-scars (BES) were responsible for the highest percentages of cull fruit for the first and second harvests. -3- Table 1.
