Autopollyplidy can be found in

Autopollyplidy can be found in Sugarcane, Cotton and Mustard.
Autopolyploidy appears when an individual has more than two sets of chromosomes, both of which are from the same parental species.
Autopolyploids can be obtained after treatment with chemicals such as colchicine or oryzalin, which affects spindle formation and induces chromosome nondisjunction during mitosis. The formation of unreduced gametes may also be a source of autopolyploid plants, like sugarcane, Cotton and Mustard.
