Abstract
An object of the present invention is to develop a novel Lobelia plant and a breeding method thereof, which allow for first-filial-generation (F1) hybrids exhibiting morphological forms (having the advantages of their two parents and far exceeding the traits of the two parents) desired by their breeder. The present invention thus provides a novel Lobelia plant by crossing Lobelia richardsonii (seed parent) and Lobelia valida (pollen parent), which while being a hybrid in first-filial-generation (F1) population of the genetically stable wild species, nevertheless the F1 population exhibits an even distribution over a range from a hybrid close to the seed parent to a hybrid close to the pollen parent.
Claims5
A Lobelia plant, that is a hybrid in first-filial-generation (F1) population obtained by
- a) crossing a genetically stable wild species Lobelia richardsonii (seed parent) and Lobelia valida (pollen parent), which crossing results in a swollen ovary in the seed parent;
- b) culturing a swollen ovule extracted from the swollen ovary to obtain a F1 plant;
- and
- c) repeating steps a) and b) to obtain the F1 population, whereby the F1 population exhibits an even distribution of morphological characteristics over a range from a hybrid close to the seed parent to a hybrid close to the pollen parent.
A method of producing a Lobelia plant that is a hybrid in first-filial-generation (F1) population, said method comprising:
- a) crossing a genetically stable wild species Lobelia richardsonii (seed parent) and Lobelia valida (pollen parent), which crossing results in a swollen ovary in the seed parent;
- b) culturing a swollen ovule extracted from the swollen ovary to obtain a F1 plant;
- and
- c) repeating steps a) and b) to obtain the F1 population, whereby the F1 population exhibits an even distribution of morphological characteristics over a range from a hybrid close to the seed parent to a hybrid close to the pollen parent.
