F1 and subsequent generation are back crossed to recurrent parent

New variety is different from the parent

New variety is identical to recurrent parent except for the character

New variety has to be tested extensively before it is released

Extensive testing is not required

Aims at improving yielding ability and other character

It aims at improving specific defects of a well adopted variety

Not suitable inter specific gene transfer

Useful for the gene transfer from related species

Hybridization is limited to F1

Hybridization is required for every back cross

Handle large population

Handle Small population

Breeding procedure same for dominant and recessive gene

Different for dominant and recessive gene
