Description Three types of seed samples (selfed, sibbed
and open pollinated) can be used for mineral
analysis in pearl millet [Pennisetum glaucum (L.)
R. Br.] and other cross-pollinated crops. Cost
effectiveness and reliability of mineral estimates
in these types of seed samples have a direct
bearing on breeding efficiency. Three sets of
experiments using a diverse range of materials
were conducted to examine the potential use of
selfed and open pollinated (OP) seed samples
for the analysis of grain Fe and Zn density in
pearl millet. The results of this study showed
that reduction in seed set under selfing, a genotype-
dependent typical trait of this crop, led
to significant and large overestimates of Fe and
Zn density, indicating that selfed seeds cannot
be used for reliable estimation of grain Fe and
Zn density. There was no significant difference
between the sibbed and crossed seeds, indicating
that there was no xenia effect. Differences
among the sibbed and OP seeds for Fe, Zn,
and Al density were small in magnitude and not
always significant, indicating that dust contamination
was not a significant factor determining
Fe and Zn density. Since production of OP seed
is most cost effective, it can be used for reliable
estimation of Fe and Zn density when dealing
with a large number of breeding lines, thereby
enhancing the breeding efficiency for these
micronutrients in pearl millet.
