The rapid evolution of the technology to face energy saving problems in protected cultivation encourages the breeder to look for new varieties. For this aim not only the potential biological yield, but also the economic end-product have to be considered.

With regard, in particular, to the new soilless-culture techniques, automation and computer-aided control, there is a clear need for new plant architectures and appropriate canopy designs, for some vegetables like tomato, pepper, eggplants.

The authors examin the possible advantages of replacing the "traditional" tomato plant model usually grown in glasshouse, with the "monostem" one. This plant architecture (side shootless, 20–30 cm high, one truss, 50–60 days from planting to harvesting) seems worthy of interest for soilless culture and close space systems aiming at a complete automation and computerization of the crop.

Similar plant architectures have recently been developed in the pepper and the bean.

To build up a plant architecture suitable for a particular microclimate and crop-management, the breeder needs suitable selection parameters. These must be singled out through physiological and biochemical studies involving adequate genetic plant material and precise growth systems.
