Genetic Variability among Different Rice Cultivars for Zinc Uptake and Utilization

Abstract: Genetic variability among eight rice cultivars was determined by conducting a solution culture experiment using modified Yoshida solution. Three Zn levels were developed by the addition of no DTPA (Zn₁), 25 μ M DTPA (Zn₂) and 50 μ M DTPA (Zn₃) to 0.035 mg L^–1 Zn. Substantial differences were observed among genotypes for accumulation of shoot dry weight (SDW), root dry weight (ROW), root: shoot ratio (RSR) as well as for zinc utilization efficiency (ZnUE). Overall Kernel genotype produced maximum SDW at all the three levels of Zn. In case of RDW genotypes Kernel, Kashmir and Basmati-370 produced maximum RDW, while DM-25 was least RDW producer. Highest RSR was exhibited by Kashmir followed by Kernel and Basmati-370. Genotypes Kernel, Basmati-370 and KS-282 showed maximum ZnUE compared to all other genotypes and could be regarded as Zn-efficient.
