Radiation-induced low-temperature tolerant cultivars of Chrysanthemum morifolium Ram

Irradiation of rooted cuttings of several chrysanthemum cultivars resulted in a relatively high frequency of mutants tolerant to lower growing temperatures (15-16 degree C instead of 17-20 degree C as is normally applied). Some of these mutants have already replaced the original parent cultivars com...

Description
Summary:Irradiation of rooted cuttings of several chrysanthemum cultivars resulted in a relatively high frequency of mutants tolerant to lower growing temperatures (15-16 degree C instead of 17-20 degree C as is normally applied). Some of these mutants have already replaced the original parent cultivars completely within three years after the beginning of the experiment. The significance of these results for practical mutation breeding of low-temperature tolerance is discussed in relation to the expected chimerism of the mutants and also to the phenomenon that some mutants represent as much as the 4th or 5th mutation generation.
