“…These wild species proved to be potential sources for other traits such as high protein content (Jennings, 1959;Nassar and Costa, 1978) compared to low protein in cassava (Nassar and Dorea, 1982;Nassar and Marques, 2006). Restoring seed-fertility (Jennings, 1962;Nassar, 2004a), apomixis (Nassar et al, 1998a(Nassar et al, ,c, 2000Nassar, 2000b;Nassar and Collevatti, 2005), resistance to mealy bug, and tolerance to drought-prone environments (Nassar, 2000c) were useful characters gained from wild species. This review updates previous reports by Nassar (1999Nassar ( , 2000cNassar ( , 2002f, 2004b on wild Manihot species and focuses on different topics reviewed by us recently.…”
