Abstract
IN conjunction with a breeding programme designed to produce plants of Tephrosia vogelii Hook f. with a higher rotenone content, multiple crosses were made between two lines of similar morphology, but of separate geographical origin. Nine dwarf plants were obtained as segregants in an F 2 population of 103 individuals. These dwarfs were characterized by greatly reduced internodes, hypocotyls, petioles, and rachises. Leaflets were also much smaller, and leaf colour was a darker green than normal. The number of leaves per plant, the number of leaflets on corresponding leaves, and the size and colour of the cotyledons were unaffected.
