Abstract Procedures have been developed that increase the rate of shoot regeneration of hybrid seed geranium from month-old primary callus cultures. Hybrid geranium callus tissue covered with green nodular structures was initiated by placing shoot tip explants on solidified Murashige & Skoog medium (MS) supplemented with 2.0 mgl-1 zeatin and 1.9 mgl-1 indoleacetic acid. Hybrids Red Orbit, White Orbit and Scarlet Orbit were shown to produce 5–50 shoot primordia per explant when callus was initiated on this medium. Regal geranium callus was initiated by placing leaf explants on MS medium supplemented with 2.0 mgl-1 6-benzylaminopurine and 2.0 mgl-1 naphthaleneacetic acid. Regal geranium cultivars Tiny Tot and Lavender Grand Slam were shown to produce between 2–50 shoot primordia per explant when initiated on the same medium.
