Variation of grain iron content in a local upland rice germplasm from the village of Huai Tee Cha in northern Thailand

This experiment examined variation of iron (Fe) concentration in grain of local Thai rice varieties from Huai Tee Cha village, in northern Thailand. Seeds of 17 named varieties were collected from farmers in 66 accessions. Brown rice from each accession was stained individually with Perls' Prus...
