Summary

Plant breeding is based on accessing genetic variability and

selecting superior plants

Tissue culture methods enable breeders to access a slightly larger

gene pool for crop improvement and also play a vital role in

transgenic plant production

Genomics methods enable characterization and manipulation of

thousands of genes to accellerate crop improvement, but no increase

in the size of the gene pool that breeders can use

Transgenic plant methods provide a dramatic increase in the gene

pool available for crop improvement
