Trading on genetic variation: fruits of Dacryodes edulis.
A brief note is given on previous and recent research into the domestication of the African plum (Dacryodes edulis) and other trees in West Africa, with special reference to a research programme conducted in Cameroon to investigate the extent and sources of genetic variation in African plum. An outline is given of additional research on genetic variation in the African plum undertaken in Cameroon in 1995, using fruits obtained from the local markets differing in colour, size and shape. The fruits differed 5.2 times in weight, 4.1 times in pulp to seed ratio and 5.4 times in price/kg fresh pulp and other characteristics. Information relevant to the domestication process, the development of genetic selection and an improvement research programme, can be obtained from simple market surveys.
