Induction of mutagenesis on Chrysanthemums

Abstract Crop genetic diversity has a significant role in improving new plants through breeding. The chrysanthemum contains the most mutant varieties, making mutation breeding one of widely utilized procedures for ornamental plants. goal this research is to use gamma irradiation induce variation and improve features. In vitro bud explants white ‘Bacardi’ type were treated with rays at 20 Gy on scope. subcultured until M1V4 growing period occurred, observations made during blooming time. Variable flower head widths, distinction plant heights numerous numbers, color size variations ray florets among mutagenic changes observed flowers. Ray varied length, width, number rows, color. frequency population was estimated 1.1% yellow-colored developed whereas control group remained white. dendrogram grouped into five groups 1, 28, 31, 41 mutants each based height stem shoots flowers per plant, florets’ number- height- color, leaves, leaf length weight flowering stems. located first, second, fourth groups. advantageous mutations could result varieties. Gamma radiation an effective mutagen creating types when applied explants.
