To estimate genetic variability in growth characteristics and phosphorus acquisition efficiency from sparingly soluble P-sources; four genetically diverse spring wheat cultivars, categorized as ‘P-efficient and low P-tolerant (class-I), and P-inefficient and low P-sensitive (class-II) cultivars’ based on P-efficiency characteristics in a hydroponic study, were grown in a sand culture in order to evaluate their relative performance in a glass house experiment. Pre-treated, cleaned uniform sized seeds of cultivars were sown in 4-kg capacity pots containing yamazuna sand with negligible available P. P-treatments were (i) (LP)-control treatment without any applied P (ii) (AP)-NH4H2PO4 @ 200 μM P kg-1 as an adequate P-supply, (iii) (TCP)-tri-calcium phosphate (Ca3(PO4)2 @ 0.5 g kg-1, and (iv) (RP)-rock phosphate @ 0.5 g kg-1 of sand. Tri-calcium phosphate and rock phosphate were sparingly soluble P-sources containing negligible P soluble in water. Biomass accumulation by plants, P-concentration and uptake in roots and shoots of plants, phosphorus stress factor and P-efficiency characteristics were differed in tested cultivars indicating sufficient genetic diversity in wheat cultivars. Biomass and growth parameters were significantly correlated with plant P-parameters indicating that P taken up by the plants from sparingly soluble P-sources was accumulated into the plant biomass. Class-I cultivars exhibited better performance than class-II cultivars indicating their better ability to scavenge P at all P levels.
