    Notes: Abstract Rooted cuttings of white flowered cv. `Purnima' and red flowered cv. `Colchi Bahar' of Chrysanthemum morifolium were treated with gamma rays. Sectorial somatic mutations in flower colour were detected in both the cvs. Mutated ray florets (yellow colour for both the cvs) were cultured on agar-solidified Murashige & Skoog basal medium supplemented with sucrose and different combinations of BAP/kinetin and NAA. Direct shoot organogenesis was noticed within 2 weeks of culture initiation. SEM studies confirmed this direct shoot differentiation. The best regeneration was obtained on medium supplemented with 0.2 mg/l NAA and 0.5 mg/lBAP. Shoots regenerated from mutated ray florets were rooted in vitro and transferred to the field. These plants flowered true-to-explant floret colour and shape. These isolated yellow mutants were maintained vegetatively have proved to be true-to-type in two successive generations.

    Notes: Abstract Rooted cuttings of Chrysanthemum morifolium cv. Maghi, a small flowered, late blooming cultivar, were treated with different doses of gamma rays. Somatic mutations in flower colour (light mauve, white, light yellow and dark yellow) and chlorophyll variegation in leaves were detected as chimeras in treated populations. Attempts were made to standardize a microtechnique for plant regeneration from mutated tissues of stem node, stem internode, shoot tip and ray floret. All these explants were cultured on Murashige and Skoog's medium with 3% sucrose, 0.8% agar and different concentrations and combinations of growth regulators. Plant regeneration was successful from all of the mutated tissues. Plants with chlorophyll variegation in leaves and two new flower colours (light mauve and white) were isolated in pure form with 64% and 100% efficiency of mutant recovery, respectively. Attempts are being made to use this technique to establish new varieties from chimeric tissues to meet the increasing demand of the floriculture trade.
