Drought tolerance contrasting cassava varieties have been screened and evaluated in four representative semi-arid environments in Brazil, Colombia, Tanzania and Ghana. Several trials have tested some hypotheses to characterise genotypes for drought tolerance traits, including: 1) genotypes that accumulated substantial stem starch reserves may be more able to sustain meristems and other respiring organs during a prolonged stress; 2) genotypes that maintain deep fibrous root growth would perform better in drought; 3) genotypes that maintain partitioning to storage roots and have high harvest index yield better in drought; and 4) genotypes that are more effective in closing stomata might be more able to maintain water status and retain leaves. |
