Abstract
Ornamental plant breeding, as other crop breeding, is considered the art and science of genetic alteration/transmutation of plants for human consumption. This paper presents a review of the literature on tissue culture in ornamental plant breeding and its applications.
Highlights
Floriculture is a dynamic and demanding activity since the quality required from the product by consumers is very high
The application of biotechnology techniques allied to conventional plant breeding methods can contribute to the sustainability of agriculture by producing cultivars which are more compatible with the environment
A change in the primary DNA structure may result in an altered phenotype, a mutant phenotype, which has four characteristics: it remains stable over consecutive cell generations; it occurs at relatively low frequencies (10-6 to 10-10) which can be increased by mutagenesis; it should be correlated whenever possible with specific genetic products, and it should be transmitted by sexual crosses (Mantell et al, 1994)
Summary
Floriculture is a dynamic and demanding activity since the quality required from the product by consumers is very high. Despite the extraordinary contribution of the conventional methods to plant breeding, there has been a consensus that significant gains cannot be expected from selection by these processes only (Barros, 1999) In this context, the application of biotechnology techniques allied to conventional plant breeding methods can contribute to the sustainability of agriculture by producing cultivars which are more compatible with the environment. The application of biotechnology techniques allied to conventional plant breeding methods can contribute to the sustainability of agriculture by producing cultivars which are more compatible with the environment This contribution is especially important to developing countries where the technological resources required to deal with problems related to tropical crops are scarce (Barros, 1999). The genetic breeding techniques discussed in this paper may appear either as complementary to classic genetic breeding programs or as techniques used for the development of new cultivars
