Description Pearl millet (Pennisetum glaucum (L.) R. Br.) is a climate
resilient crop with higher nutrition and serve as staple food
for several million populations in semi-arid regions of India
and Africa. To utilize the nutritional variability of this crop,
biofortification research has been initiated to combat
micronutrient malnutrition, chiefly iron (Fe) and zinc (Zn)
deficiency. Large variability for grain Fe and Zn density has
been reported in pearl millet and mostly the high-Fe lines
had relatively dark grey grain colour. Therefore, this study
was designed to investigate the effect of grain colour on
grain Fe and Zn density in pearl millet. Two dark grey lines
were crossed with five white grain colour lines to produce
10 hybrids. These hybrids were evaluated along with their
parental lines for Fe and Zn density in two seasons. Highly
significant Fe density differences observed for both parents
and hybrids while significant Zn density differences
observed only for hybrids. The significant genotype ×
environment (G × E) interaction observed for Fe and Zn
density in hybrid trial. Interestingly, grain colour×
environment variance was not significant for both
micronutrients. Results indicate both micronutrients were
not differed from white to grey grain lots among hybrids
(70-103 mg kg-1 Fe density and 64-80 mg kg-1Zn density),
implying the genetic improvement of grain Fe and Zn density
in pearl millet is highly feasible without compromising the
grain colour preference of the farmers and consumers.
Further, highly positive and significant correlation between
these two micronutrient density irrespective of the grain
colour recommended increase in Zn density as an associated
trait while breeding for high Fe density in pearl millet.
