Description Little millet (Panicum sumatrense Roth. Ex. Roem. & Schult.), a member of the
grass family Poaceae, is native to India. It is nutritionally superior to major cereals,
grows well on marginal lands, and can withstand drought and waterlogging
conditions. Two-hundred diverse little millet landraces were characterized to assess
variability for agronomic and nutritional traits and identify promising accessions.
Highly significant variabilitywas found for all the agronomic and grain nutrient traits.
Accessions of robusta were high yielding whereas those of nana were rich in grain
nutrients. About 80% of the accessions showed consistent protein and zinc (Zn) contents
whereas iron (Fe) and calcium (Ca) contents were less consistent (29.5 and
63.5%, respectively) over 2 yr. Promising trait-specific accessions were identified for
greater seed weight (10 accessions), high grain yield (15), high biomass yield (15),
and consistently high grain nutrients (30) over 2 yr (R2 = .69–.74, P ≤ .0001). A few
accessions showed consistently high for two or more nutrients (IPmr 449 for Fe, Zn,
Ca, and protein; IPmr 981 for Zn and protein). Five accessions (IPmr 855, 974, 877,
897, 767) were high yielding and also rich in Ca. Consumption of 100 g of little millet
grains can potentially contribute to the recommended dietary allowance of up to
28% Fe, 37% Zn, and 27% protein. Multilocation evaluation of the promising accessions
across different soil types, fertility levels, and climatic conditions would help
to identify valuable accessions for direct release as a cultivar or use in little millet
improvement.
