The invention of an indehiscent mutant (analogous to nonshattering home grains) by Langham in 1943 started the work towards improvement of a high-yielding, dehiscence-resistant selection. Although researchers have made vital progress in sesame breeding, harvest losses because of dehiscence continue to limit domestic US manufacturing. Tanzania stays the largest producer of sesame oil and also dominates the global consumption of this product. The African and Asian regions constitute the quickest-developing sesame oil markets.
