Abstract
Dry and healthy seeds of three Bambara
Groundnut Landraces; Alkaleri cream (Alk-C), Alkaleri mottled (Alk-M) and
Alkaleri black (Alk-B) were irradiated with varying doses of Gamma rays (0, 50,
100, 150, and 200 Gy) from 60Co source and planted in polythene pots
under nursery conditions, which were arranged in Complete Randomized Design
(CRD) format and replicated three times. There was significant reduction in
seed germination rate with the increase in gamma radiation in all landraces,
with maximum germination rate (89%) recorded in the control treatment.
Seedlings of the irradiated population showed deleterious effects of Gamma rays
at the higher doses (150 and 200 Gy), with significant reduction in all
parameters studied (plant height, number of branches, number of leaves,
terminal leaf length and terminal leaf width). Considerable increase in plant
height and number of branches at the low dose (50 Gy) was observed, compared to
the control population as indicted in the positive shift in their mean values.
The Alk-B landrace showed more tolerance to the gamma radiation treatment in
seedling establishment by recording significantly higher mean values in most of
the parameters compared to the other landraces. The positive shift in mean
values of some of the parameters studied, due to Gamma radiation treatment at
50 Gy dose implied that this mutagenic agent has the potential to improve
certain characters in Bambara Groundnut landraces.
