Determinacy — Tomato (Interspecific Hybrids)

hybrids between Solanum lycopersicum L. and S. habrochaites S. Knapp & D.M. Spooner

Determinacy in interspecific hybrids of S. lycopersicum and S. habrochaites defines the growth termination type of the main stem after the formation of a specified number of flower clusters.

In the reference 12 varieties crop hybrids between Solanum lycopersicum L. and S. habrochaites S. Knapp & D.M. Spooner, where this is mentioned in the description.

The trait is assessed as a qualitative characteristic in which the main stem of the plant ceases development, terminating in an inflorescence. In the breeding of introgression lines, this parameter is critical: the selection of hybrids with a determinate growth type is necessary for creating forms suitable for industrial processing and mechanical harvesting.

The presence of determinacy dictates the planting pattern, plant density, and pruning methods for the hybrids. Since this trait is linked to the distribution of photosynthates and vegetation periods, it is monitored alongside fertility indicators to ensure that the introgression of genes from the wild species S. habrochaites has not compromised the commercially valuable plant habit.
