Spontaneous sexual and asexual polyploids occur in cassava. The cassava polyploid breeding strategies using these polyploidization processes are discussed. Sexual polyploidization has advantages over asexual polyploidization in terms of viability of gametes, heterosis, vigor, plant architecture, ...

The sodium picrate test for hydrocyanic acid was used (0 evaluate BB.S10cassava plants for cyanogenic content. Acyanogenic plants were not found in spite of the large number of plants rested. A small number of plants exhibited low to medium degree of cyanogenesis while the rest of [he plants show...
