### Biochemical Composition of the Yam Genotypes
All the yam genotypes studied (Table 2), including the white yam (control), are significantly different (\(p\) < 0.001) in their biochemical composition except for sugar, which is not significantly different (\(p\) > 0.05). [PERSON] et al. (2019) reported high genotypic variations in biochemical composition amongst the different genotypes of yam species that were studied. Considering the effects of locations, namely Ikenne, Ibadan, and Ubiaja, on the biochemical properties, the results showed that different planting environments significantly affect all the biochemical parameters (Table 3). \begin{table}
