Controlled environment research on tomato (Solanum lycopersicum) is often hindered by large plant size. Desired cultivar traits for research include a compact plant size, fast flowering time, and good fruit set. We grew eight micro-dwarf tomato cultivars to examine their suitability as model plants for research. The cultivar ‘Rejina Red’ had the highest harvest index and most ripe fruits among the red-fruited cultivars; ‘Jochalos’ had the highest harvest index and most ripe fruits among the yellow-fruited cultivars. ‘Microtina’ had a higher harvest index than ‘Rosy Finch’, but fruits were smaller, and growth was less determinate. ‘Monetka’ had a germination rate of only 6% and low fruit set. ‘Rejina Red’ and ‘Jochalos’ had compact growth and excellent fruit set, and we recommend them for use in future tomato-based studies.
