Stable and heritable sorghum mutants are produced in which the development arrest of the pedicellate spikelets is released. In these mutants, all spikelets, both sessile and pedicellate, develop into flowers and produce mature seeds, thereby significantly increasing seed production and yield in comparison to wild-type sorghum. These mutants may be crossed with other sorghum lines, particularly elite large-seeded lines, to improve grain yield in sorghum and other related species.
