P1-The name of the parent to which a hybrid is crossed in a backcross.
F2- generation : The progeny resulting from self hybridization or inbreeding of F1 individuals is called Second Filial or F2 generation.
F1- generation : The progeny produced from a cross between two parents (P1) is called First Filial or F1 generation.
inbred 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.
Homozygous - An individual possessing (receiving from parents) identical alleles for a trait is said to be homozygous or pure for that trait, e.g. plant with RR alleles is homozygous for the seed shape. A homozygous always breeds true for that trait.
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
Capitate-Botany: forming a head like mass or dense cluster, as the flowers of plants in the composite family. Enlarged and globular at the tip.
Dominant - said of an allele which by itself alone will produce a particular phenotype regardless of which other allele may be present on the other matching chromosome of the diploid pair; thus it takes only one copy of the chromosome to cause a dominant trait to be expressed in the phenotype.
Genome - the total genetic information possessed by an individual, a breed or a species.
Genotype - the invisible genetic makeup of an individual organism, which includes alleles which may be recessive and therefore have no visible physical expression.
