Abstract: With the flowering regulation technology of cassava recently developed by our research team, we successfully induced bisexual cassava flowers. These bisexual cassava flowers had the ability for self-pollination bearing fruits. Here, we report the morphological characteristics of bisexual cassava flowers and their capsules and seeds from self-pollination development. Bisexual flowers contain both pistils and stamens, but unisexual flowers contain only one of these. The bisexual flower capsule is ovate and has a large length/width, but the unisexual flower capsule is broadly ovate and has a small length/width. The raphe of bisexual flower seed is not uplifted, but that of unisexual flower seed is uplifted. Bisexual flowers and their seeds are valuable for studying heredity and breeding in cassava, which has important significance for revealing heritable characteristics and cultivating new germplasm in cassava．
