Abstract
Fruit Characteristics (pod length, number of pod per bunch, pulp and seed weight, pulp weight
and pod breadth), Seed Characteristics (number of seed per bunch, expected seed number per
pod and seed weight per bunch), and Qualitative Characteristics of seeds (seed colour, shape,
size and texture) of Parkia biglobosa (Jacq) G. Don population were investigated in this study.
Twenty six (26) P. biglobosa population were sampled at the permanent site of the University of
Ilorin, Nigeria, in May 2010 and fruits were collected from these populations for study. Pulp and
seeds were removed manually from the dry brown indehiscent pods by using hand to break the
pods along their sutures and de-pulping was done by manual washing with hands in water. There
were significant differences (at P=0.05) among the fruit and seed characteristics of 26
populations of P. biglobosa investigated. Five (5) plants showed high pod number per bunch with
20 pods and above while long pod lengths were observed in seventeen (17) plants. Two (2)
plants have narrow pointed tip pods (apex) and four (4) plants with broad pod breadth. One (1)
plant has its apex size similar to its base (1.53cm). Seventeen (17) plants were observed to have
more than 100seeds per bunch while, only one plant was noticed to exhibit wrinkled seed coat,
the fifteen (15) plants had flat oval seeds. Two (2) plants had pure black seed coat and twenty
four (24) had brownish seed coat colours. Larger percent of the plants have medium seed size,
five (5) plants have small seed size and others are of big size.
