Seeds of Antirrhinum majus (snapdragon), proprietary line OAK564, were treated with 0%, 0.10%, 0.25%, 0.5%, 0.75%, and 1.0% ethyl methanesulfonate (EMS) for 8, 10, and 12 h at room temperature. The experiment was replicated three times over time. Data were collected on percent seed germination, seedling survivability, and pollen viability to determine optimal conditions for induced mutagenesis in OAK564 seeds. In the pilot experiment, M1 seeds treated with 1.0% EMS for 12 h had the lowest seed germination rate among all 18 treatments. Based on this pilot experiment, a large-scale mutagenesis experiment was performed using three levels of EMS (0.5%, 0.75%, and 1.0%) for 10-h exposure period. Mutants were induced on all these treatments, and morphological changes in the M1 population were detected. These included dwarfism, chlorophyll deficiency, and leaf morphology abnormality. This indicated that the EMS treatments were successful in inducing mutations, and mutants were further characterized for morphological traits.

Production of high tunnel tomatoes and snapdragons was evaluated over a 2-year period at the Wiregrass Experiment Station, in southeastern Alabama. `BHN 640', `Florida 91', `Sunleaper', and `Carolina Gold', were evaluated in early Spring 2004. Results indicated that `BHN 640' outperformed `Florida 91' and `Carolina Gold' in early production of high tunnel grown tomatoes. A late Fall 2005 study examined `BHN 640' and `Florida 91'. Results indicated that `BHN 640' was superior to `Florida 91' in total marketable fruit. Season extension of both spring and fall tomato production were accomplished. A planting date study was completed in the early Spring 2005. The following four planting dates were evaluated: 31 Jan., 17 Feb., 4 Mar., and 25. Mar 2005. Wind damage to the high tunnel caused some mortality; however, the two earliest planting dates (31 Jan. and 17 Feb. 2005) produced over 10 lbs. of marketable tomatoes per plant. These were both superior to the last planting date of 25 Mar 2005. Cut snapdragons were evaluated for suitable colored mulch (red, white, or blue) and varieties for summer (`Opus Yellow', `Opus Rose', `Monaco Red', and `Potomac Early White') and fall (`Apollo Purple', `Apollo Yellow', `Monaco Red', `Monaco Rose', and `Potomac Early Orange') production. Results indicated that inflorescence length was affected by the color of mulch. The red mulch had increased inflorescence length compared to the white in Summer 2005. The Fall 2005 study revealed that white mulch had longer inflorescence length than the red or blue mulch. Some varietal differences were observed. The `Apollo Purple' had longer stem lengths than all other varieties for the fall study. The summer study revealed that `Opus Yellow' had longer inflorescence lengths than all others but stem lengths were all similar.
