Described is a method for obtaining a plant having a height of less than the height of a corresponding wild type plant, comprising the steps of transforming tissue of the wild type plant with one or more genes of the Ri plasmid of Agrobacterium rhizogenes allowing the transformed tissue to develop roots selecting a putatively transformed root having a hairy root phenotype growing said root on a regeneration medium regenerating a shoot from said root, thereby generating a transformed rooted plantlet growing said transformed rooted plantlet into a mature transformed mother plant having a height of less than 65% of that of the corresponding wild type plant preparing a transformed cutting from the mature transformed mother plant, or from progeny thereof, allowing a rooted transformed plantlet to develop from the transformed cutting, and treating the rooted transformed plantlet with gibberellin, therewith allowing the plantlet to develop in a mature plant having a height between the height of the transformed mother plant of step and the height of the wild type plant of step.
