Abstract
To identify rice cultivars with low grain cadmium (Cd) levels, 42 cultivars of Thai rice (Oryza sativa L.) were cultivated in a Cd-contaminated field in the Pha Te village, Mae Sot district, Tak province, Thailand, from 2009 to 2011. Among non-glutinous and late-ripening cultivars, lower levels of Cd accumulated in the grains of RD5, RD15, and Sang Yod than in Khao Dawk Mali 105, a prevailing and popular cultivar in this area. Among glutinous and late-ripening cultivars, Khao' Niaw Ubon 1 and Khao' Niaw Ubon 2 accumulated lower Cd levels than a prevailing cultivar RD6. The findings suggest that human cadmium intake can be reduced by selecting low-Cd rice cultivars. © 2012 Copyright Taylor and Francis Group, LLC.
