A first generation offspring obtained from two selected purebred plants.
the first generation of hybrids after crossing two varieties.
A plant which grows from seed produced as the result of a controlled cross between two genetically unlike parents. Such hybrids are usually very uniform. Crosses between two inbred lines, between one inbred and a single-cross hybrid, or between two single cross hybrids, are called single, three way and double cross hybrids respectively.
A plant derived from a sexual cross between two homozygous but different parents.
A cross between two unrelated plants. Seeds from F1 Hybrids will not produce replica parent plants
Refers to the first generation of offspring plants produced by a cross of two genetically different parent varieties. F1 hybrids can have advantages, including the robust growth known as "hybrid vigor," homogeneity, and the fact that they are often bred to be disease resistant. Seed saved from F1 hybrids are unpredictable, however, and are sometimes sterile.
The first generation offspring of a plant created by crossing two distinct pure species.
(In this context) the result of crossing, often by hand, two specially selected and highly bred parents. The resultant plants are usually very uniform, often very prolific and seed is always more expensive than seed of open pollinated or F2 hybrids (see below). Most familiar bedding plants such as petunias, impatiens and geraniums are F1 hybrids. Seed taken from F1 hybrids usually produce plants unlike both the F1 hybrid and its parents.
The "F" in F1 hybrid stands for filial or offspring. F1 means the first generation offspring after cross-pollination. The majority of F1 hybrids are sterile or produce offspring unlike themselves. See also "hybrid."
the first generation of a hybrid crossing
The first generation cross between two strains, between two inbred strains, between two lines, etc.
A first generation offspring of two purebred strains. An Fl hybrid is generally more vigorous than an ordinary hybrid.
F1 hybrids are the first filial generation seeds/plants or animal offspring resulting from a cross mating of distinctly different parental types, the offspring of which produce a new, uniform variety with specific and/or desirable characteristics from either or both parents. In fish breeding, those parents frequently are two closely related fish species, while in plant and animal genetics those parents usually are two inbred lines. Mules are F1 hybrids between horse and donkey.
