The influence of genetic variability on the response of the five rice varieties, Cica, Starbonett, Lemont, Bluebonett X IR 43, and IR43, to applied zince at 0, 10, 20 and 40 kg Zn ha^-1 under varying cellulose and water management conditions was studied in a greenhouse experiment. Typical zinc deficiency symptoms, varying in intensity among varieties, were nted, especially in the zero applied zinc treatments. Zinc deficiency symptoms were characterised by blanching at the base of the emerging leaves and rusty brown discolouration in the older leaves.
