Everett and Karen A. Armbrester A replicated trial was conducted at the Southwest Florida Research and Education Center, Immokalee, Florida, during the spring season (January-May) of 1987 to evaluate the performance of twenty-four 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 (1.5x1.5x2.5 inch cell size) on December 18, 1986, and were transplanted to field plots on February 2, 1987. 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 52 feet apart. There were 6 plant beds and a drive middle between lateral ditches. On January 16, 1987 all plots were fertilized with 7 lb. of 5-16-8-1.8 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. A total of 14 lb. of 19-0-30/100 LBF was 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 Vorlex at 21 ounces/100 LBF 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 and diseases were not a serious problem in this test. General weather conditions during this trial are shown in Table 2. February and March were cool, windy and considerably wetter than usual. After a light frost on April 5 conditions were generally warm and dry for the remainder of the season. Tomatoes were harvested on May 6 and May 11, 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 and % color at first harvest for each of the 24 entries. Marketable yields for the first harvest ranged from a high Professor and Biologist, respectively, IFAS, University of Florida, Southwest Florida Research and Education Center, Immokalee, Florida 33934 -2- of 1486 25-lb cartons/7260 LBF for 7181 to a low of 418 25-lb cartons/7260 LBF for 7195. Fourteen of the 24 entries were statistically equal for highest first harvest yield. Yields from all entries were statistically equal at the second harvest. Twelve entries were statistically equal for highest combined first and second harvest yields; 'Pacific' (2594 25-lb cartons/7260 LBF), 'Royal Flush' (2422), 7168 (2417), Hybrid 26 (2347), 7181 (2342), 'Bingo' (2340), 'Horizon' (2317), PSR 76184 (2305), 'Duke' (2248), 7196 (2181), 'Gator' (2151), and ACX 8412 (2098). Entry 7195 had the lowest total marketable yield at 1167 25-lb cartons/7260 LBF. Using percent color (breakers and red ripes) at first harvest as an indicator of earliness, 'Jackpot' at 53.6% color was the earliest maturing variety along with 'FTE 12' (51.1%), XPH 5129 (48.6%), 'Duke' (41.1%), Hybrid 26 (40.8%), 'Horizon' (40.6%), 'Bingo' (39.1%), ACX 5x5 (38.1%), and 'Floratom II' (37.0%) (Table 3). 'Pacific' showed the least color at first harvest at 8.5% and was judged to be one of the later maturing varieties along with PSR 76184 (17.6%), 7178 (19.1%), 7181 (20.9%), 'Sunny' (21.2%) and 7168 (22.8%). Average weight of fruit for the first harvest (Table 4) ranged from a high of 9.1 oz. for 'Bingo' to a low of 6.4 oz. for XPH 5031, with ACX 5x5 at 8.7 oz. and 7178 at 8.6 oz. statistically equal to 'Bingo' for the heaviest fruit. At the second harvest eight varieties were statistically equal for the heaviest fruit. They are 'Bingo' (5.9 oz.), 7178 (5.8), 'Royal Flush' (5.8), ACX 5x5 (5.8), 'All Star' (5.7), PSR 34283 (5.6), 7195 (5.6), and 'Duke' (5.5). Percent cull fruit are shown in Table 5 and categories of cull fruit, by harvest, are shown in Tables 6 and 7. Cull production was not very great during this experiment and ranged, at first harvest, from 3.6% culls for 7168 to 16.0% for 'Jackpot' and at second harvest from 1.7% for 7181 to 15.1% for 'Jackpot'. Causes for cull production were varied at both harvests, however, cat facing and zipper scars were more predominant at first harvest. -3- Table 1.
