Mutagenesis
Polyploidy
Cross Breeding
Protoplast Fusion
Transgenesis
Genome Editing

1) Combining two sexually compatible species to
create a variety with the desired traits of the parents

2) Utilization of mutagens such as radiation to induce
random mutations creating the desired traits

3) Use of an enzyme system to modify DNA directly
within the cell

4) The addition of genes from any species to create a
new variety with desired traits

5) Multiplication of the number of chromosomes in a
crop to impact its fertility
Combination of cells or cell components to transfer
traits between species
