Abstract
The variation exhibited within populations of the
Date Palm (Phoenix dactylifera, L) in Nigeria would appear
to suggest that these populations originated from seedlings.
The distribution of the palms in the arid and semi arid
sudan and subsudan ecological zones of Nigeria suggests that
climatic factors like low rainfall, low humidity and high
temperature may have favoured their adaptation in these zones.
In the absence of recognised varieties, random sampling
of populations was practised. Twenty four population types
were recognised and their fruit and seedling characteristics
described. A population type was defined as the mean
performance of a population of palms sharing a common gene pool
within a single location.
Collection and evaluation of the locally adapted
genotypes is a long term investment for the systematic
improvement of the Date Palm in Nigeria. It is suggested
that the Samaru Germplasm Repository fulfils the need for
such an investment.
