Why is mutation breeding still attractive for breeding of chrysanthemum?
Languages of publication
Many cultivars of chrysanthemum as well as other ornamental crops on Polish market are of foreign origin. Such situation is not to the advantage of Polish producers because of high royalties. There is a necessity of providing new Polish cultivars of ornamental crops, including chrysanthemum. Traditional breeding methods such as cross-breeding are not expensive but take much time and cannot be always applied for ornamental crops, which are usually heterozygous, poliploids and are vegetatively propagated. On the other hand, there are modern techniques including genetic transformation, but they are often out of reach for Polish breeders due to very high costs. Mutation breeding is a relatively inexpensive and easy method of obtaining new cultivars. Twelve new cultivars of chrysanthemums have been obtained as a result of mutation breeding research, carried out in the Departament of Ornamental Crops and Vegetables at University of Technology and Agriculture in Bydgoszcz. Induced mutations most often led to altered inflorescensce colour and shape, growth habit and other traits. Both induced mutations and regeneration in vitro using adventitious buds technique apear to be useful tools in breeding of chrysanthemum.
