Propagating Antirrhinum

INTRODUCTION

This protocol describes general strategies for propagating Antirrhinum (snapdragon) species: self- and cross-pollination, cuttings, and grafting. Antirrhinum majus cultivars and some wild species are self-fertile, but they require self-pollination for high seed yields. Although self-fertile, A. majus shows unilateral incompatibility and can only be crossed to other self-incompatible species as the female parent. All Antirrhinum species can be propagated clonally from cuttings. Antirrhinum also readily forms grafts within and between species.
