Abstract
The soilless system is used for a double process consisting of robust phenotyping,
of the available continuously implemented germplasm, often on multiple cycles during
the year, and the contemporaneous breeding programs on raspberry, strawberry and
blueberry, that include population development, phenotyping and genotyping for
marker development for particular traits of agronomic importance.
The aim of this
report is to present the management strategy adopted at FEM, based on soilless
techniques as a flexible and optimized system.
This allows for commercial introductions
to readily screen new cultivars for their attitude to the local environment and cultural
system.
Concerning breeding, it allows better synchronization and increased numbers
of annual hybridization cycles, to improve seedling growth efficiency and to reduce –
through opportune plant manipulations the time to selection.
For both purposes, it
helps with evaluating the genotypes under different environmental conditions in the
same period of time, optimizing growing factors like temperature, pH, water and
nutrients and facilitating disease control.
