Abstract: Selenium (Se) plays a major role in human and animal’s diet. Because of the low concentration of Se reported in staple foods such as rice, developing a Se fertilizer strategy would play a key role in increasing Se levels in the human body. Se uptake in relation to morphological root parameters among 6 lowland rice varieties was studied by conducting a solution culture experiment using modified Yoshida solution in Agriculture Faculty of University Putra Malaysia. Three Se levels were developed by the addition of 0, 20 and 200 mgL-1 Na2SeO3 and rice seedlings were harvested in week 4. Se uptake in roots of rice showed significant differences among all varieties and Se uptake significantly increased with increased in Se levels. Other root parameters (length, average diameter, surface area, volume and number of root tips) did not show any significant differences at different Se treatments.
