At the peduncle end, the depression of the fruit of 'TO16-0113' is medium while it is weak for that of the reference varieties. At the blossom end, the fruit shape of 'TO16-0113' is indented to flat while that of 'Merlice' is flat to pointed. The fruit of 'TO16-0113' matures mid to late season while that of 'Merlice' matures early to mid-season. The plants of 'TO16-0113' are resistant to Oidium lycopersicum while those of the reference varieties are susceptible.

Origin & Breeding History: 'TO16-0113' originated from a controlled cross conducted by Valerio Primomo at the Vineland Research and Innovation Centre located in Vineland, Ontario. The cross was made in 2016 between two proprietary inbreds. In 2017, 'TO16-0113' was included in hybrid screening trials in Vineland, Ontario and further trialed in Vineland and Leamington, Ontario in 2018 and 2019. The hybrid tomato variety 'TO16-0113' was selected in November 2018 for its uniform fruit clusters, fruit yield, shelf-life colour, flavour and disease resistance.

Tests & Trials: The comparative trials for 'TO16-0113' were conducted in the same greenhouse and row (trough) in 2021 and 2022 at the Vineland Research and Innovation Centre in Vineland, Ontario. The trial included a total of 24 plants each of the candidate and reference varieties. Each plot contained 12 plants with 2 replicates. The plot was 4 metres squared, with 3 heads per metre squared in 40 metre long rows. All plants were grown in 10 cm rockwool blocks spaced 25 cm apart and grafted onto Kaiser rootstock with the cotyledon pinched. The observations and measurements were taken from 24 plants, or parts of plants, of each variety from February 15 to June 24 in 2021 and from February 28 to June 16 in 2022. Disease resistances were assessed in separate disease nurseries on 23 plants for Fusarium oxysporum f. sp. lycopersici race 0 (ex1) and race 1 (ex 2), and 32 plants for Oidium neolycopersici (On). Assessments were based on the standards used to describe disease susceptibilities.
