In 1999, the habanero was listed in the Guinness Book of World Records as the world's hottest chili, but it has since been displaced by a number of other peppers, the record tending to change every few years. The bhut jolokia (or ghost pepper) and Trinidad moruga scorpion were eventually identified to be native Capsicum chinense subspecies even hotter than the habanero, and breeders constantly crossbreed the various subspecies to attempt to create cultivars for the Scoville scale record - for instance, the Carolina Reaper crosses a ghost pepper with a particularly piquant red habanero.
