Glossary A

Here are some basic terms you should know for breeding. P1-The name of the parent to which a hybrid is crossed in a backcross. original parental generation used to develop F1 hybrids or stabilizing true breeding

F1– generation : The progeny produced from a cross between two parents (P1) is called First Filial or F1 generation. When you cross two different IBL strains for the FIRST time, it is called the F1 generation.

F2– generation : The progeny resulting from self hybridization or inbreeding of F1 individuals is called Second Filial or F2 generation.

Inbred backcrossed line- (IBL) – A line produced by at least five generations of sequential inbreeding, self fertilization or backcrossing accompanied by selection within and between lines so that the individuals are considered to be homozygous, or nearly so. is a genetically homogeneous strain that grows uniformly from seed. An IBL is homozygous, or true breeding for particular traits. Not the same as Land Based Species (originals).

Phenotype – The external (morphological) appearance of an individual for any trait or traits is called the phenotype, e.g. for seeds, round shape or wrinkled shape is the phenotype The observable, qualifiable and quantifiable representation of a trait.

Genotype – the invisible genetic makeup of an individual organism, which includes alleles which may be recessive and therefore have no visible physical expression.

Hybrid– A strain made up of two genetically unknown parents.

Off-spring– The progeny or descendants of a plant considered as a group. Out-cross– A female crossed with a male with the soul intention of inbreeding the sibling line to the mother plant. Pistil– The female, ovule-bearing organ of a flower, including the stigma, style, and ovary.Pistolate – Female

Stamens-The pollen-producing reproductive organ of a flower, usually consisting of a filament and an anther. Staminate – Male

Trait… A genetically determined characteristic or condition: a recessive trait.
