Abstract excerpt
Centuries of clonal propagation in cassava (Manihot esculenta) have reduced sexual recombination, leading to the accumulation of deleterious mutations. This has resulted in both inbreeding depression affecting yield and a significant decrease in reproductive performance, creating hurdles for contemporary breeding programs. Cassava is a member of the Euphorbiaceae family, including notable species such as rubber...
