Manganese (Mn) deficiency limits wheat productivity on sandy loam,
calcareous and alkaline soils cropped with rice. Variation of wheat genotypes
to sustain production and Mn use from Mn deficient condition was
investigated to screen efficient genotypes. Forty-seven diverse wheat
genotypes were evaluated on Mn sufficient (0.195 mM) and Mn deficient
(0 mM) nutrient solution to elucidate physiological basis of Mn deficiency
tolerance and to develop manganese deficiency tolerance index (MDTI).
Shoot dry weight and mean Mn accumulation was 136.7% and 76.5%
enhanced when Mn nutrition was improved, respectively. Efficient genotypes
under limited Mn had lower root length/shoot weight ratio but higher
relative shoot growth rate with higher shoot demand on root which reflected
higher Mn influx. Genotypes were classified as tolerant (>0.66), semi-tolerant
(0.33–0.66) and sensitive (
