Grain arsenic accumulation is independent of agronomic traits in rice under field conditions.

ABSTRACT: Arsenic (As) is a toxic environmental pollutant and a group-1 carcinogen, posing serious concern for human health. Rice and rice-based food products are considered as one of the major sources for As contamination into the human food-chain. Hence, world-wide concerted research efforts are going on, either to identify and/or develop low-As accumulating rice genotypes. The present study evaluated the natural accessions of rice, comprising of landraces and farmer's varieties, under the naturally As-contaminated sites of Chhattisgarh, India, which is well-known for its richness in terms of rice production as well as varietal diversity. The wide-range spectrum of grain-As was obtained in 120 selected genotypes, with 90 and 81 accessions having As-accumulation above the WHO permissible limit for
