Successful production of haploid, triploid and pentaploid as well as diploid was achieved in the plants restored from anther callus and tetraploid from ovary callus, although only diploid plants were restored from embryo and shoot nodule callus. A series of plants in polyploid, x, 2x, 3x, 4x, and 5x, showed the ploidy-specific properties in morphological characteristic points.
