The development of seedless tomato fruits will be more attractive to both consumers and industries. Seedless tomatoes can be
produced through parthenocarpy technology. Artificial parthenocarpy can be induced by conventional crossing, hormone
application, or genetic engineering. The development of parthenocarpic tomatoes through genetic engineering has been carried
out by inserting DefH9-iaaM parthenocarpic geneinto tomato genome via Agrobacterium tumefaciens mediated transformation.
Sixty putative transgenic tomato lines were produced and three events (OvR1#14-4, OvM2#10-1, and OvM2#6-2) were selected
as the best events. The background of the tomato lines was Oval variety, and based on PCR results, the three selected lines
contained DefH9-RI-iaaM in their genome. The objective of this research was to determine the integration of DefH9-RI-iaaM
gene in the progenies of three transgenic tomatoes lines using PCR technique. The research was conducted in the laboratory
and Biosafety Containment Facility of Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and
Development (ICABIOGRAD). Parental variety, Oval (neither transgenic nor in vitro cultured), and elite line of CL 6046 were used
as control plants. The results indicated that the progenies (T1, T2, and T3) of the three tomato lines contained the insert DefH9-RIiaaM
