Abstract
Investigation of the pattern of inheritance and
nature of gene action governing the inheritance of
some quantitative traits and the qualitative purple
gene marker were carried out in pearl millet. Continuous
variation was observed for plant height, ear length,
ear girth and leaf area.
The gene number varied from as low as -5.77 to
3.98. There were involvements of both additive and
non-additive gene actions in the inheritance of each of
the quantitative traits. Apparent indications of
skewness in some F2 data distributions indicated the
presence of complementary gene action. Low negative
and positive heritability estimates were observed
probably resulting from poor genetic diversity of parent
materials. Similarly low heterosis and inbreeding
depression were observed.
Discrete distribution and digenic inheritance of
the purple gene marker on the seed, midribs and whole
plant were observed. Probability values were low for
each of the purple plant parts. Low probability values
may have resulted from low level of homozygosity of
the parents with the purple marker.
