Description
The variety constitution process of the forage Crops Institute of Lodi is characterised by: 1) the exploitation of interference effects (competition): 2) the utilisation of a selfing phase; 3) a synthetic variety formula based on parental clones derived by several parental populations, The phenotypic choice of mother plants and the progeny tests are made in dense swards. The research on competition has allowed the formulation of an ideal model of the lucerne (Medicago saliva L.) stand and of the plant ideotype, The ideal model of the lucerne stand is characterised by the synchrony of the individual plants for the physiological traits allowing a Oniform response to cutting. A phase of selfing is very effective in an autotetraploid plant like lucerne, When partly inbred material is used, a free-doublehybrid is the best variety model for forage production but not for seed production. A 6-way or 8-way free-hybrid variety seems to represent the good solution for both seed and forage production
