e and Zn deficiencies are most prevalent especially in children and females
and is directly correlated with food insecurity. The aim of current study was
to screen maize germplasm for micronutrient’s level. Sixty-eight maize inbred
lines were sown during autumn season-2017 and spring season-2018 in soil
having optimal level of Fe and Zn. All agronomic practices were performed
accordingly and well in time. Data was collected for plant height, no. of cobs
per plant, cob length, no. of rows per cob, no. of seeds per row, no. of seeds
per cob, 100 seed weight, grain yield, phytic acid, Fe and Zn contents. Results
of genotypic variance, phenotypic variance and heritability suggested that
Zn had higher values 262.49, 284.43 and 92.29 respectively than Fe 39.05,
62.06 and 62.93. Correlation estimates showed that Fe and Zn had positive
correlation with each other, plant height and 100 seed weight, while had
negative association with grain yield and phytic acid. Genotypes were grouped
into 5 clusters on basis of genetic diversity. Cluster-4 showed highest values
of Fe and Zn while Cluster-3 had lowest. High variability for Zn (12.99-81.31)
and Fe (15.99-52.75) among Inbred lines and good heritability provide a basis
for development of improved genotypes with good Zn and Fe levels. Positive
association of Fe and Zn suggests that both can be improved simultaneously,
as biofortication is the most feasible way to provide micronutrient rich food to
consumers.
