Abstract

During last few decades arsenic contamination has emerged as a major environment problem. The irrigation through arsenic-laden water significantly elevates the arsenic concentration in soil which influences the growth and development of different crops. It is necessary to identify wheat genotype that has ability to grow in arsenic contaminated soils with low arsenic uptake efficiency. A hydroponic method had proved useful tool for screening plants. The present study was conducted to identify contrasting As accumulating wheat genotypes by in different levels of arsenate 50M, 250M in hydroponic experiment. The results revealed that highest As uptake was observed in Pbw550 genotype (HAWG) and the lowest As uptake by Wh711 genotype (LAWG). All the fifteen wheat genotypes were ranked with respect to their As tolerance index: Wh711&
