In a harvest scheme such as this, many of the improved varieties lose their dry yield as starch is converted to sugar. A modified breeding scheme has been suggested to evaluate selected lines from 12 to 24 MAP. Such varieties should mature early at 12 MAP and maintain or enhance their root dry matter rather than losing it. Depending on the market needs, some producers prefer to keep their crops up to 24 MAP and harvest sequentially when needed. Cassava evaluation trials are mostly harvested at 12 months after planting (MAP) irrespective of their actual maturity date, which includes the maximum accumulation of dry matter in tuberous roots.
