Principles of Plant Breeding (2+1)

Comparison of back cross and pedigree method

Pedigree	Back Cross
F1 and subsequent generation are allowed for self pollinated	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
