The preliminary results obtained by Cha´ vez et al. (2005)
suggested a good potential for genetic variability of protein
content in cassava roots but it was based on single
measurements. Therefore, an extensive data search was
conducted to identify cassava germplasm whose roots had
been analyzed for protein content more than once. A total
of 149 clones from the germplasm collection at CIAT, as
well as a few improved clones (Table 1), whose roots had
been analyzed more than once, were found. For each clone,
the analysis was conducted in different years and on
different roots from plants grown at CIAT’s experimental
station in Palmira, Colombia. Therefore, differences in the
environmental conditions of where the plants were grown
resulted mainly from year-to-year climatic variation and
were expected to be low.
