that <strong>the</strong> pulp of a Nigerian provenance was poor in proteins (87.9 g/kg) and<br />

oil (25.3 g/kg). Soloviev et al. (2004) looked at fruit composition, especially<br />

in relation to total stable sugars, total free acidity and water content in a<br />

range of genotypes in Senegal. Such chemical characters varied widely but<br />

less than biometrical ones related to morphological characterisation. Such<br />

studies are helpful in selecting suitable genotypes <strong>for</strong> enhanced<br />

domestication.<br />

The pulp contains oil, which is greenish in colour and liquid at room<br />

temperature. The saponification value of <strong>the</strong> oil is high but <strong>the</strong> iodine value<br />

is low. Some physico-chemical properties of <strong>the</strong> pulp and seed are shown in<br />
