Abstract
Hybrids of onion and garlic or Chinese chive are obtained by culturing the ovule-embryo after fertilization of the male (e.g. garlic pollen) and female (e.g. onion egg cell) gametes. The hybrids have the useful characteristics of both species and can be propagated.
Claims11
A hybrid cell of an onion and garlic or a hybrid cell of an onion and a Chinese chive, which is characterized by having totipotency including both embryogenic ability and differentiation potency and which is obtained by crossing an onion with either garlic or a Chinese chive by (a) fertilization of an onion with garlic pollen or of garlic with onion pollen or (b) fertilization of an onion with Chinese chive pollen or of Chinese chive with onion pollen, in which the hybrid cell is further characterized by genetic characteristics in the cytoplasm which are inherited exclusively from the maternal plant.
A method for obtaining a hybrid embryo of an onion and garlic or a hybrid embryo of an onion and a Chinese chive, which comprises culturing a hybrid ovule obtained by crossing an onion with garlic or an onion with a Chinese chive by (a) fertilization of an onion with garlic pollen or of garlic with onion pollen or (b) fertilization of an onion with Chinese chive pollen or of Chinese chive with onion pollen, said hybrid embryo being capable of germinating, differentiating and growing.
A method for propagating a hybrid plant of an onion and garlic or an onion and a Chinese chive, which comprises cultivating a clove, an aerial bulbil or a seed of the hybrid plant.
A method for propagating a hybrid plant of an onion and garlic or of an onion and a Chinese chive, which comprises aseptically removing the growing point of a clove, a shoot or a root of said hybrid plant and culturing the hybrid growing point in a plant culture medium to effect clonal propagation of said hybrid plant.
A method for obtaining a hybrid cell of an onion and garlic or a hybrid cell of an onion and a Chinese chive, which comprises (a) fertilizing an onion with garlic pollen or garlic with onion pollen or (b) fertilizing an onion with Chinese chive pollen or Chinese chive with onion pollen.
